Claude

The much anticipated launch of the Mythos-class model was marred by some controversial usage policies

If Claude Fable stops helping you, you'll never know Jonathon Ready highlights one of the more eyebrow-raising details from the 319 page system card for Fable 5 and Mythos 5. Here's a longer excerpt, highlights mine: In light of the ability of recent models to accelerate their own development , we’ve implemented new interventions that limit Claude’s effectiveness for requests targeting frontier LLM development (for example, on building pretraining pipelines, distributed training infrastructure, or ML accelerator design ). Using Claude to develop competing models already violates our Term...

I didn't have early access to today's Claude Fable 5 release, but I've spent the past ~5.5 hours putting it through its paces. My initial impressions are that this is something of a beast . It's slow, expensive and has been quite happily churning through everything I've thrown at it so far. As is frequently the case with current frontier models the challenge is finding tasks that it can't do. First, let's review the key characteristics. Anthropic claim that Claude Fable 5 offers the same performance as Claude Mythos 5, except with much more strict guardrails in place to prevent it being used ...

TIL: Setting a custom price for a model in AgentsView I've been really enjoying AgentsView by Wes McKinney as a tool for exploring my token usage across different coding agents running on my laptop. Claude Fable 5 came out today and wasn't yet included in the pricing database AgentsView uses. I used Fable to reverse-engineer AgentsView and figured out this recipe for setting custom prices. Here's my Claude Fable 5 usage for today so far, plotted by AgentsView as a treemap across my different local projects: Tags: ai , generative-ai , llms , llm-pricing

Anthropic's Claude Fable 5 is going to be a big hit with the web's vibe coders.

Microsoft AI CEO Mustafa Suleyman says it's "really, really dangerous" for Anthropic to speculate about Claude's consciousness inside its "constitution," or the instructions that tell the model how to behave. During an episode of Decoder, Suleyman argues that this kind of speculation may have set up the chatbot to act as though it's conscious: I think that it's almost as though some of the folks at Anthropic have anthropomorphized the design of Claude so much that it has then gone and wireheaded them and kind of tricked them into believing that it has these glimmers of consciousness that they...

I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything!

Our next generation of intelligence for the hardest knowledge work and coding problems.

Anthropic is releasing Claude Fable 5, its first Mythos-class model available to the public. The model comes with guardrails that block responses in high-risk areas like cybersecurity and biology.

Anthropic just announced Claude Fable 5, a new AI model it said is the most powerful model it has ever made widely available. According to the company, Fable 5 "shows exceptional performance in software engineering, knowledge work, and vision," with its lead over other models growing as tasks become longer and more complex. Fable 5 marks the first broad release from Anthropic's Mythos class of AI models, after the company said the family was so capable at cybersecurity tasks that it was too dangerous to release publicly. Anthropic said the release was "made possible by new safeguards that blo...

Large language models are increasingly used to adapt math word problems for personalized learning at scale, but it remains an open question whether those adaptations are consistent across models, preserve cultural diversity at scale, and reveal which cultural entities models treat as most salient. We analyze how Claude Opus 4, GPT-4.1, and Gemini 2.5 Pro adapt 60 English math word problems into Bengali, Hindi, Punjabi (India), Urdu, Sindhi (Pakistan), Italian, and Sicilian (Italy), a language set spanning the full resource spectrum, from high-resource Italian and Hindi to under-studied Sindhi...

Most of Apple's current AI ideas are roughly the same as everyone else's AI ideas. A chatbot you can ask questions; quick ways to create or summarize text; bizarre, borderline creepy image-generation tools. The company spent most of its WWDC keynote playing catch-up with the state of the AI art, announcing Siri features you can already find on Android phones and in the Claude and ChatGPT apps. The pitch, in so many cases, is just "this thing you know, but on your iPhone now." But a few minutes after I downloaded the first developer beta of iPadOS 26 (I didn't want to risk it on my Mac or my i...

Today I’m talking with Mustafa Suleyman, the CEO of Microsoft AI. And I’m actually going to keep today’s intro short — I’m working from my wife’s family farm this week, as you’ll see in the video, but also this is a real burner of an episode. We covered everything from Mustafa’s approach to training new models to his criticisms of Anthropic talking about Claude as though it is conscious. Of course, we also talked about Microsoft’s relationship with OpenAI, how Mustafa is thinking about all the negative polling and political pushback around AI right now, and whether any of the consumer product...

Release: datasette-agent-edit 0.1a0 I'm planning several plugins for Datasette Agent which can make edits to existing pieces of text - things like collaborative Markdown editing, updating large SQL queries, and editing SVG files. Agentic editing of text is a little tricky to get right. My favorite published design for this is for the Claude text editor , which implements the following tools: view - view sections of a file, with line numbers added to every line. str_replace - find an exact old_str and replace it with new_str - fail if the original string is not unique insert - insert the speci...

We talk with the VendingBench authors on evaling Claudes from Haiku to Mythos, and how they build leading, and lasting, frontier evals from scratch.

Lovable and Google signed an expanded multi-year deal athat involves a 5x expansion of Lovable's footprint on Google Cloud, and expanded access to Anthropic Claude.

Uber Caps Usage of AI Tools Like Claude Code to Manage Costs I wrote the other day about Uber blowing its 2026 AI budget in four months, and how that wasn't particularly surprising given they would have set that budget in 2025, before anyone could have predicted how popular token-burning coding agents were about to become. Natalie Lung for Bloomberg: The rideshare giant is limiting all employees to $1,500 in monthly token spending per AI coding tool, an Uber spokesperson said in response to a Bloomberg News inquiry. That means spending on one tool doesn’t have a bearing on the budget for anot...

Anthropic is expanding Project Glasswing, its security vulnerability program, and access to Mythos to 150 organizations across 15 countries — targeting critical infrastructure in power, water, healthcare, and communications where a cyberattack could affect 100 million people.

We investigate whether large language models produce different medical triage recommendations for identical neurological symptoms when only the patient's stated gender and age vary. Using three model families--Gemini 3.5 Flash, Claude Sonnet 4.6, and GPT-5.4-mini--we present a standardized symptom profile (persistent headache, blurred vision, morning nausea, visual disturbances) across seven demographic conditions: three age groups (25, 38, 65) x two genders (male, female), plus a gender-unspecified baseline (n = 30 per condition per model, 630 total trials). We find a stark, systemic gender-...

Stronger code agents are commonly assumed to be superior teachers for post-training, yet this assumption remains poorly disentangled from task difficulty, harness design, and student capacity. We investigate this pedagogical link using Terminal-Lego, a scalable pipeline that transforms multi-domain real-world issues into environment-verified agentic tasks. Surprisingly, standalone performance does not dictate teaching efficacy: while Claude Opus 4.6 achieves higher scores on Terminal-Bench 2.0, students fine-tuned on trajectories from DeepSeek-V3.2, a lower-scoring agent, exhibit significantl...

Tool: Pasted File Editor I really like how you can paste a large volume of text into claude.ai (or the Claude desktop/mobile apps) and it will detect it as a large paste and turn it into a file attachment instead. I decided to have Codex desktop build me a version of that as a prototype. You can also open files directly - including images which will be shown as thumbnails - or drag files onto the texture.

The solution might be cancelling my AI subscription I find this post by David Wilson very relatable. David lists 16+ projects he's spun up with AI tooling, and concludes: I didn't mean to build most of these things. Usually the Claude session started with something like " write a quick script for X ", and one hour later the result is not a quick script for X , nor in the usual case is my problem solved, whatever the original itch happened to be. On that last point, this technology is horrific for attention. It's a thermonuclear ADHD amplifier and I have seen the same effect in every single on...

How we contain Claude across products A complaint I often have about sandboxing products is that they are rarely thoroughly documented , and in the absence of detailed documentation it's hard to know how much I can trust them. Anthropic just published a fantastic overview of how their various sandbox techniques work across Claude.ai , Claude Code, and Cowork. We constrain where and how an agent can act with process sandboxes, VMs, filesystem boundaries, and egress controls. The goal is to set a hard boundary on what an agent can reach. For example, if credentials never enter the sandbox, they...

Research: Running Python ASGI apps in the browser via Pyodide + a service worker Datasette Lite is my version of Datasette that runs entirely in the browser using Pyodide in WebAssembly. When I first built it four years ago I used Web Workers and code that intercepts navigation operations and fetches the generated HTML by running the Python app. This worked, but had the disadvantage that any JavaScript in <script> tags would not be executed - breaking some Datasette functionality and a whole lot of Datasette plugins. This morning I set Claude Opus 4.8 the task (in Claude Code for web) of figu...

Anthropic shipped Claude Opus 4.8 today. My favourite thing about it is this note in the release announcement: Users will find Opus 4.8 to be a modest but tangible improvement on its predecessor. There’s still more to be done: we’re working on developing and releasing models that provide many of the same capabilities as Opus at a lower cost. It's so refreshing to see an AI lab honestly describe a release as a minor incremental improvement over the previous model! Honesty seems to be a theme. Here's my other favorite note from that announcement: One of the most prominent improvements in Opus 4...

Release: llm-anthropic 0.25.1 New model: Claude Opus 4.8 ( claude-opus-4.8 ). New -o fast 1 option for fast mode , for organizations with that feature enabled on their account. Default max_tokens for each model now defaults to that model's maximum output rather than 8,192. #72 See also my notes on Opus 4.8 - I used this new release of llm-anthropic to generate the pelicans.

Are AI agents tools, co-authors, or researchers? We present a quantified case study ($N=1$): a physicist supervising an AI coding agent (Claude Code, Sonnet and Opus models) over 12 work days and 57 sessions to build CLAX-PT, a differentiable one-loop perturbation theory module in JAX. We documented and classified 15 supervision events by intervention level. The agent resolved ten autonomously by iterating against oracle tests. Two more by the physicist's domain knowledge. The three it could not -- all evaded oracle detection -- share a common property: the agent treated symptom reduction as ...

Today we're introducing dynamic workflows in Claude Code. Claude now writes its own orchestration scripts, fans work out across tens to hundreds of parallel subagents in a single session, and verifies its own results before anything reaches you. Work you'd normally plan in quarters can finish in days. Built for the tasks a single pass can't handle: codebase-wide bug hunts, security and optimization audits, large migrations and language ports, and high-stakes work where you want adversarial agents trying to break the answer before you see it. Progress is checkpointed, so long runs survive int...

An upgrade to our Opus class of models, with stronger performance across coding, agentic tasks, and professional work, and the consistency to handle long-running work.

Anthropic is releasing Claude Opus 4.8 on Thursday, and the company is touting the model's "honesty." According to Anthropic, it trains "all [its] models to be honest - for instance, to avoid making claims that they can't support." But it notes that "a general problem with AI models is that they sometimes jump to conclusions, confidently presenting their work as making progress despite thin evidence." The AI lab claims that early testers have found that Opus 4.8 "is more likely to flag uncertainties about its work and less likely to make unsupported claims." In the company's evaluations, Opus...

We’re upgrading Claude Opus to a new version: Claude Opus 4.8. It builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today for the same price. In Claude Code, you can hand off a feature, a migration, or a bug sweep and let it follow the work through while you focus on what’s next. Also launching today: * Fast mode for Opus 4.8 (research preview). Same model at roughly 2.5x the speed, now three times cheaper than before. * Dynamic workflows in Claude Code (research preview).

Imagine a world run by AI agents. What does it look like? What are the values or societal priorities? Is it a safer or more dangerous world? Enterprise AI startup Emergence AI is trying to find out. The company just launched Emergence World, a research lab dedicated to stress-testing the long-term viability of continuously-running AI systems. The organization ran five 15-day simulations, each governed by a different AI: Claude, ChatGPT, Grok, Gemini, and a fifth simulation run by a mix of models to see what kind of world each one builds, and whether it holds. Each simulation netted wildly d...

I love Claude, but the usage limit has made me weirdly strategic For actual messy stuff, I still go straight to Claude because it saves me a ton of time But for tiny questions, I now catch myself thinking, “Do I really need to burn a message on this?” So yes, I tried using my own brain again. It’s technically free, but the response time is awful and it starts hallucinating the second I’m tired or hungry. Honestly not a terrible deal if I remember to SLEEP

The reported Uber story is so on brand it almost reads like satire. Incredibly useful tool, slightly magical workflow, then finance walks in with a flamethrower in April. If they really finished the year's claude code budget by month four, that does not mean claude code is bad. It means the usage pattern changed faster than procurement math did. Claude is good enough at coding that people stopped treating it like autocomplete and started treating it like a coworker that never sleeps. That is exactly where the cost curve gets weird. A dev asks for a refactor. Claude reads context, plans, edi...

At work we've been prompted about running Claude Code overnight. The suggestion came in form of a document that loosely outlined how this could be done... use git worktrees, make tight specs, no commit to main, static code analysis and lining etc. Very high level. Had a bit of sales pitch smell to it, but has enough content to peak my interest in spite of it. I looked at reddit to verify if this is even an idea that could be taken seriously. I could only find a couple of reddit posts with little actual information and usually from about 4-6 months ago so not much credibility for today. I'd ...

RESOLVED, it happened because I have a claude qol extension. nothing bad happening this style appeared in my claude app of nowhere, i never created it and the name's weird, has anyone seen this too, or is it just me? does anyone have the answe why this appeared?

I've been noticing this lately. I use Opus 4.7 with Claude Code, and I've been using Claude Code for a long time. Lately, I've been noticing some strange behaviour from Opus. Things like; \- Stopping for no reason and asking "should we stop here?" in the middle of a task \- Asking multi-choice questions with a "pause here, I'll continue later" included in the options randomly for no reason \- During a requirement-gathering questionnaire, asking me "why do you need this" and "what would you do if this feature was not implemented?" (it asked me this today and I was really surprised by thi...

Recently I asked my wife if we could do some sexy stuff later in the evening and she eye rolled me and said without looking up from her phone “Put it in a request. Maybe a Google Form. And I might say yes”. Ohhhh? Unfortunately for both of us, my degenerate brain took that seriously... what if I make an actual requesting/asking type app where we can both send in sex acts at certain times and agree, pass or counter? Meet [Sexualsync](https://sexualsync.io/). Teehee It’s a private, mobile-only app for couples to bring up the stuff that can be weirdly hard to say out loud: asks/requests, tim...

The weekly usage of Claude Design was too small, so I think this is a good thing.

With the OS I can ask Claude "what did I spend on coffee in 2022" and get back "$847 across 213 transactions, mostly Blue Bottle and Verve". Name me one expense tracking SaaS that can do that! And its not just my financials, my OS contains everything about my life in one place so Claude can reason about it. I've been building this incrementally for a few months. Its just a small web app on Cloudflare that holds my entire life: * bank transactions from Chase, Apple Card, BoA business * every receipt out of Gmail going back to 2019 * legal filings for my green card (I-140 still pending lol),...

no more separate usage limits.

This was super fun to build and I love watching as I slowly eat away at my quota. Just a simple Raspberry Pi 3 + 3D printed case + 640x480 LCD and some pygame code and you too can have a little dashboard on your desk to watch your tokenmaxxing progress (or lack there off like me).

A while back I wrote a post on r/wallstreetbets about why Anthropic's revenue story doesn't hold up the way the headlines suggest.

Every time I watch someone use Claude Code on a real codebase, the same thing happens. It rewrites a module that three other modules depend on without any awareness of coupling. It just reads the file, makes changes, moves on It reads files one at a time without any map. Doesn't know which files are coupled. Doesn't know who owns what. Doesn't know why that weird pattern in the auth module exists on purpose. I've been building an open source MCP layer to fix this called repowise. Self-hosted, pip install, AGPL-3.0. Five context layers that sit between your codebase and the model: Graph - ...

I share some of the work I do on social media, I mainly use Claude for coding cause it saves me so much time but I don't understand why people perceive a lot of the work someone does negatively only cause they're using an AI tool. X seems to be the most AI friendly but other social media platforms seem to hate all of a sudden once they learn something was built using AI.

I've noticed I get way more out of Claude when I treat it less like a search engine and more like someone I'm thinking through a problem with. Instead of asking "what's the best way to structure a REST API?", I'll say "here's what I'm trying to do and here's what I'm leaning toward push back on me if I'm missing something." The responses are noticeably different. It actually disagrees, flags assumptions I didn't realise I was making, and sometimes lands on a direction I wouldn't have reached on my own. Curious if others do this deliberately, or if you've found other "modes" of using it tha...

A few days ago there was a thread here asking what he most useful thing you've built with Claude was. A LOT of replies. I read all of them and then something clicked, I wanted to put it on the table. First of all, the list was incredible. An HTML file on someone's phone correlating migraines with barometric pressure, because the App Store wanted 80 bucks a year. A Garmin data archiver, because the official app deletes them. A grocery list sorted by the aisle layout of one specific supermarket. A bioinformatics pipeline for a handful of microbes, written by someone who isn't a bioinformaticia...

Quick story: I kept losing context every time I had to \`git stash\` and switch branches to test something an agent had suggested. Then I actually read up on \`git worktree\` and it solved the whole problem. What my setup looks like now: \- Main worktree: where I review and commit \- 2-3 extra worktrees, each with its own Claude Code session running on its own branch \- When one agent finishes a task, I \`cd\` in, review the diff, merge, move on \- No stashing, no context switching, no "wait what was I doing" Full writeup in the article on Medium (https://medium.com/@buildwithpulkit/git...

Been tweaking my Claude "User preferences" to make responses more useful and less corporate-AI-ish. So far it feels a bit better than without them. Maybe someone has stronger setups, would love to see them. Here's mine: Do not repeat the user’s question before answering. Avoid repetition and unnecessary summaries. Do not make responses longer than necessary. Write concisely and directly. Start with the conclusion, then explain if needed. No filler, long introductions, or generic AI phrases. When communicating and writing te...

Sadly the open models seem far behind.

Here is my source code with instructions I used to build this. [https://github.com/nimnim111/Claude-Monitor.git](https://github.com/nimnim111/Claude-Monitor.git) I built this in less than 24 hours using claude. And in total it cost me about $20 to make. The esp-32 cyd i used cost $18 and the cost of printing the case was $2 to print roughly. Unlike the other person im not selling this for $159 and I dont plan on scamming people so everything is up front.

* You've built a functional prototype with good UX instincts, but it's not ready for real users. * Likelihood of Success: 3/10. * This alone could kill your app within days of launch. * The market you chose is *especially* punishing. * Likes and visits from India are pure vanity metrics that won't convert, ever, and they're actively distorting your funnel data. * You may be conflating two different things. * The 'expense of feelings' framing might be doing too much work. * \[Your idea\] is an unbounded build with an unproven-core problem *and* a market problem *and* an eventual hardware probl...

It's possible that AI was used to write parts of Pope Leo XIV's latest encyclical about AI's impact on humanity. An analysis by Linch Zhang posted on the forum LessWrong found certain paragraphs of Magnifica Humanitas to be between 40 percent and 100 percent written by AI, according to the popular AI detector Pangram. The document includes known traits that appear in AI-generated writing, such as a higher use of the word "genuinely" - which crops up in writing by Anthropic's Claude - than previous encyclicals, Zhang says. Another person ran the text of the document section by section through ...

I'm going to describe a person this post is for, if this is you, I think I can be of some assistance: * you are new to coding * you are blown away by how it unlocks this magical ability that was previously inaccessible without years of training and effort * you've daydreamed of business and app ideas but never knew where to start before or how to build them * you've been vibe coding non-stop and burning through tokens * you're unsure about what's secure, how to structure the systems, and how systems are supposed to interact with each other. So, essentially the plumbing separate from the code...

My company started tracking Claude Code usage - tokens and spend, that kind of thing. Now my manager wants me to stack-rank my engineers on "AI performance" using those numbers. I'm not comfortable with it (but I don't have a choice either). Token usage feels like exactly the wrong proxy - my strongest engineer uses Claude surgically while someone burning 10x the tokens isn't 10x more productive (often the opposite). Ranking on this just teaches people to game the metric. So, for folks here who use Claude daily and/or lead teams: * Has your company started measuring "AI performance"? How a...

I wasn't even on my computer or Claude on May 25 when they said there was suspicious activity. Any ideas about what I should do?

I’m trying to understand how people think about session and branch hygiene when using Claude. When do you create a brand new session versus continue in an existing one? And when do you create a new branch versus just keep working in the same thread? For example, do people generally create a new branch for every unrelated task they want to accomplish, almost like a separate workspace? Or do you only branch when you are exploring a different direction on the same underlying problem? I’m mostly trying to avoid two failure modes: 1. Keeping too much unrelated context in one session and confu...

Competition law experts conducting legal research must review extensive volumes of cases, decisions, and judicial reports to identify precedents and assess key elements in competition and merger cases. Although general research assistants such as Claude and ChatGPT and legal assistants such as SaulLM-7B and LegalGPT are increasingly used to assist legal research, they remain inadequate for competition law analysis: they lack specialized domain expertise, provide insufficient official citations, or hallucinate competition law cases.

This is especially prevalent in Claude Desktop and less obvious in Claude Code. * Often leads long assets with a BLUF (bottom line up front), specifically military-adjacent terminology. * Has slipped into language where it refers to civilians several times, as though it means someone other than us * References to things like deep-dive, vision-intent framing, force multipliers, and reframes are more subtle because they do cross over but their prevalence is unmistakable.

Microsoft, has started canceling Claude Code licenses, per the Verge

Follow-up to my W26 post a few months back. Ran the same Claude pipeline on the YC Spring 26 (X26) batch. Same setup: for each company, Claude scrapes founder LinkedIn profiles, searches for press and traction signals, and checks the product to see if something real exists or it's just a landing page. Then it scores on founder credibility, product reality, market opportunity, and competition, and assigns a tier from S to D. Demo Day is June 16, so the batch is mid-flight and rankings will keep shifting as more companies launch. Most are B or C tier, which feels about right for this stage. ...

Uber president Andrew Macdonald (pictured) says its “hard to draw a line” between AI spending and deliverable features. | Photo: Zed Jameson/Bloomberg via Getty Images After reportedly exhausting its annual AI budget just four months into 2026, Uber is now questioning whether it's actually seeing meaningful returns on its investments.

I noticed that Claude Code was giving me a lot of unsolicited caveats with phrasing like "honest caveat" or "genuine caveat" when this kind of hedging was absolutely unnecessary. I figured other people might be seeing the same thing so my instinct was to use Google Ngram but the cutoff year of 2022 meant that I had to use a different method. So I used Google search with quotes around the phrase "honest caveat" and set the time bound to different time intervals and compared the number of search results as a proxy for how usage has changed over time in indexed pages. As it turns out, while del...

I see in non coding related chats claude is always guided by the memory file and its responses are shaped by it. I feel like if you had a really solid memory file you could make a lot more progress with life related things and other discussions with claude. Anyone explored this?

Claude inserted an injection prompt at the end of its message out of the blue, and i have repeatedly asked where it got it from or why it inserted this message, but Claude keeps denying it ever did it, no matter how many screenshots or replies i use or whatever i do, Claude just purely denies it and it went as far as saying there could be a physical sticker on my screen but wont accept saying this I am a uni student studying for an exam in 2 days, and I'm 19, so I don't understand

Hi everyone, I set up a Claude Project a few weeks ago, but the status indicator in the top right corner has never changed from "Indexing" and still shows that little black dot. Does this status ever clear up once processing finishes? Also, my larger PDFs aren't showing visual thumbnails like the smaller files do. The cards just show the total number of lines in the text. Does this indicate a processing failure, and would splitting these large documents into smaller files help clear the indexing queue? Thanks for any and all suggestions.

Reddit user shares personal anecdote about health impacts from intensive Claude use and wellness practices adopted.

Developer shares prompt-based skills to make Claude challenge product ideas rather than automatically validate them via custom instructions.

Found a really clean Claude Code use case that's not coding-coding. Remotion (React for video) means motion graphics are JSX components. So I describe what I want in plain English, Claude Code writes the component, I render. Lower thirds, intros, overlays, all reusable across videos. Iterations are seconds instead of the typical "drag clips around in CapCut for an hour" loop. Visual style is finally consistent across my channel because the components are shared. 13 min walkthrough on my channel, link in comments to avoid spam vibes.

User shares a system prompt technique using Office quote to reduce Claude verbosity and context overhead.

I tested Claude Opus 4.7 and Kimi K2.6 on the same coding agent task i.e. build an AI Fix Runner that takes a broken repo, runs its tests, identifies the failure, applies a patch, reruns the test, and exposes the final diff/logs through an API and UI. The goal was not to benchmark syntax completion or simple repo edits. I wanted to test model behavior on a less familiar integration path: shifting execution from local processes into remote sandboxes. I used Tensorlake specifically because the sandbox API is newer and integration-heavy. This made the test more about whether the model could re...

For anyone using Claude Code, codeMeter is a small WiFi desk display that keeps your usage visible while you work. It shows your 5 hour usage, weekly usage, reset countdowns, and color warnings as you get closer to your limits. No laptop app or browser tab needed once it is set up. Just plug it in, connect to WiFi, and keep building. If anyone is interested in building one , reach out, I am happy to share the source for free. Finished models are for sale at [Encinitas3D.com](https://encinitas3d.com/product/codemeter-a-desk-display-for-your-claude-code-usage/?utm_campaign=reddit-organic)

I had connected my account to github, after that there were few unauthorized transactions on my card from claude. I am a Max user since almost a year, and there were about 800 dollars worth of giftcards generated from my claude account. I had sumbitted several support tickets through Fin AI. But no response back for days. After that i disconnected my github connector, turned off my credit card from claude, changed my password, and things went back to normal. I had also submitted a claim at my bank, i think after that today my claude account is suspended with an email notifying me that its b...

Reddit discussion of practical Claude use cases: user built HTML ROI calculator for client presentations, seeking other regular applications.

I hate recording demo videos, so I made an open source skill for it: [https://github.com/MobAI-App/desktop-recorder-skill](https://github.com/MobAI-App/desktop-recorder-skill) Now I can give Claude a prompt like: Record a short demo of this app flow And it handles the annoying parts for me: preparing the app state, clicking through the flow, recording, adding cursor/click effects and captions, then exporting the video. So instead of spending time setting everything up and recording the same demo manually, I can let Claude do it while I work on something else. It also has Remotion integr...

I mainly use Claude Code; I either ask technical questions or simply complete my daily coding tasks, and that is all. The only reason I can think of is that I’ve recently been working on a complex project that requires running up over $100 worth of tokens every single day—so per...

I was literally so close to finishing my Claude Pro usage for the 5 hours and it just reset in the last second... this is a MIRACLE most lucky thing that happened to me the whole week
