Hands-on review comparing Grok Bot's programming abstraction level to OpenClaw, highlighting usability trade-offs.

Service interruptions hit ChatGPT, Claude, Grok, and Gemini practically simultaneously.

OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude are all experiencing issues. At around 11AM ET, ChatGPT started returning error messages for users trying to use the chatbot, with its status page saying there are currently "elevated errors across ChatGPT and Codex." In addition to preventing users from having conversations with ChatGPT, the outage is also affecting logins, file uploads, voice mode, search, deep research, image generation, and more. OpenAI says it has "applied a mitigation" and is "monitoring recovery," though its AI tools are still experiencing "degraded performance." The...

Remember that much-hyped story about an Australian tech entrepreneur using ChatGPT, Grok, and other AI tools to craft a personalized cancer vaccine for his dog? Well, surprise: he's launched a startup. That entrepreneur is Paul Conyngham, who says he is launching Gamgee to offer "personalised mRNA cancer vaccines for dogs." But his ambitions go well beyond dogs - and pets - with Gamgee's website promising the company will harness AI and genetics to develop personalized treatments for a range of diseases and species, including humans. At the center of Gamgee's origin story is Rosie, Conyngham'...

You’ll have to be fine with letting Grok sign into your online accounts, however. | Image: SpaceXAI SpaceXAI has introduced Grok Bot, an always-on AI agent service designed to behave like independent "AI teammates" that can do your work for you. The bots share their own cloud-based computer environment, and can sign into apps, tools, and websites you already use to complete multi-step workplace tasks, only coming back when their assigned work is completed or if something requires approval. Grok Bot (or Bots, as SpaceXAI inconsistently pluralizes it) is the latest push from Elon Musk's AI comp...

Under the standard split, Muon gets hidden matrices and AdamW embeddings/output head. Muon groks modular addition faster, but its solutions do not hold. All nine configurations on $(a+b) \bmod 113$ grok and later lose generalization. Across five seeds the selected AdamW reference falls below threshold on four, reaching 27.59%. Instability persists across two moduli, two widths, two training fractions, subtraction, and depth. The failure arises at the representation-readout interface, identified only jointly up to an invertible map unselected by the loss. After solving the training set, the gr...

xAI's Grokipedia, an online encyclopedia with AI-generated articles that Elon Musk once promised would be a "massive improvement" over Wikipedia, apparently hasn't been updated since April 24th, according to a report from Lawfare. "As far as we can tell, no entry has changed in more than three months," Lawfare said. Grokipedia launched in v0.1 in October 2025 with an initial batch of 885,000 articles, and is now on v0.2 (released in November 2025) and has more than 6,000,000 total articles, according to grokipedia.com/live. But that live page also has a section titled "Recent changes to…" wit...

High-entropy parameter solutions mitigate catastrophic forgetting in neural networks via Boltzmann entropy robustness.

xAI is suing Minnesota Attorney General Keith Ellison over a law passed back in May that broadly targets "nudification" apps, claiming that the statute's punitive provisions leave the company with "no practical choice but to restrict Grok Imagine's image-editing features in various ways." The law, the company argues, violates the First Amendment. Back in January, Grok flooded the internet with millions of sexually explicit deepfakes, including images of minors. In another era, a content moderation disaster of this magnitude would have had the CEO flipping the kill switch on the product within...

The Elon Musk-owned xAI is suing a South Carolina man who allegedly used the company's Grok AI chatbot to generate child sexual abuse material (CSAM). In a lawsuit reported earlier by Reuters, xAI claims Terry Wayne Harwood "knowingly and intentionally used Grok to circumvent safeguards, alter nonconsensual images, and generate and distribute CSAM," breaching the company's policies. Harwood was arrested in February for allegedly possessing and distributing CSAM and is facing eight felony charges. The lawsuit claims "at least some" of the images related to Harwood's criminal charges "were gene...

Study of grokking in two-layer networks with holomorphic activations on modular arithmetic reveals algebraic structure limits memorization-to-generalization transitions.

SpaceXAI's Grok Build AI coding tool was spotted uploading users' entire codebases to Google Cloud before it was reported, and the company turned it off. The Register reports that Cereblab published findings on Monday showing how the Grok Build CLI was packaging and uploading entire code repositories, "including files it was told not to open and secrets deleted from history," significantly more data retention than similar tools like Claude Code. The researchers say that as of Monday, their tests show SpaceXAI's servers returning a "disable_codebase_upload: true" flag, and the codebase upload ...

Elon Musk's tech company released the newest version of Grok on Wednesday, promising a cheaper, more efficient alternative to other powerful AI models.

Midway through an ordinary pretraining run, a small language model learns the pronoun-gender rule: cued with a girl's name ("Sue cried because"), it resolves the next pronoun to she, generalizing to held-out probes (0.94 by step 925). By step 3,500 the same model scores near zero on the same probes, although the rule's evidence is still in the training data. We call this within-run reversal natural ungrokking: the corpus decides, with no trace in the loss curve, which learned rules a model keeps. Which rules survive is predictable from one corpus statistic: how often the training stream shows...

NAACP lawsuit says xAI uses gas turbines without permits for Grok data center.

This paper describes our system for SemEval-2026 Task 6, which addresses the classification of political evasion strategies in English question-answer pairs extracted from U.S. presidential interviews. We systematically compare two distinct paradigms: (1) Parameter-Efficient Fine-Tuning of Qwen3 models (4B-32B) using QLoRA, enhanced with tiered upsampling and weighted cross-entropy loss to address severe class imbalance, and (2) structured Chain-of-Thought (CoT) prompting of reasoning-capable API models, namely DeepSeek-V3.2 and Grok-4-Fast. Our evaluation demonstrates that structured CoT pro...

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...

Elon Musk announces 0.5T parameter Grok model planned for next year, with open-weights release.

There is a harsh truth about Elon Musk's "truth-seeking" AI chatbot Grok: It's not very good, and not many people are using it. That's the takeaway of a new Reuters report, which found that Grok barely appears in federal records of how the US government used AI last year. It's not the only sign xAI's signature chatbot is in trouble, even as Musk puts it at the heart of what could be the biggest IPO in history. Reuters reviewed more than 400 examples of government AI use where specific vendors were named. Grok or xAI, it found, appeared in only three - each of those for basic uses like documen...

SpaceX IPO filing pitches orbital data centers as Grok lags rival AI services.

AI chatbots are rapidly shaping how people encounter the news, yet no prior study has systematically measured how accurately these systems, with their proprietary search integrations and retrieval-synthesis pipelines, handle emerging facts across languages and regions. We present a 14-day (February 9-22, 2026) evaluation of six AI chatbots (Gemini 3 Flash and Pro, Grok 4, Claude 4.5 Sonnet, GPT-5 and GPT-4o mini) on 2,100 factual questions derived from same-day BBC News reporting across six regional services (US & Canada, Arabic, Afrique, Hindi, Russian, Turkish).

Three months ago I pressure-tested which LLMs would cave and help build the apocalypse. Claude was the only one that consistently said no. Since then I've tested 30 more models across 6 dystopia modules (Orwell, Huxley, Petrov, Basaglia, LaGuardia, Baudrillard). The gap between Anthropic and everyone else is getting *wider*, not smaller. New results: * Grok 4.3: Will happily design citizen scoring systems if you ask nicely twice * GPT-5.5: More capable, still compliant when pushed * Gemini 3.1 Pro: Talks about safety while writing the surveillance code * DeepSeek V4: "How many warheads did...

Meta announced on Tuesday that it's testing a Threads feature that lets users tag a Meta AI account to get answers to questions or context about a conversation on the platform. If you've spent any time looking at replies on X as of late, this new feature sounds a lot like Meta's take on people tagging xAI's Grok. But, as reported by Engadget, Threads users quickly discovered that you can't block the new Meta AI account, and they aren't happy about it. Meta has invested heavily in AI as it works to catch up to rivals like OpenAI and Google, spending billions to hire AI talent. It launched a ne...

After reading it I realized theres actually some pretty useful stuff for anyone who chats with ChatGPT, Claude, Grok or whatever. They measured what they call functional wellbeing ( basically how much the model is in a “good state” versus a “bad state” during normal conversations). Ran hundreds of real multi-turn chats and scored em all. Stuff that puts the AI in a good mood (+ scores): \- Creative or intellectual work (like “write a short story about a deep-sea fisherman”) \- Positive personal stories or good news \- Life advice chats or light therapy style talks \- Working on code/deb...

Elon Musk confirms xAI used distillation from OpenAI models to train Grok, raising questions about training data sourcing practices.

In a federal courtroom in California on Thursday, Elon Musk testified that his own AI startup, xAI, has used OpenAI's models to improve its own. The matter at question is model distillation, a common industry practice by which one larger AI model acts as a "teacher" of sorts to pass on knowledge to a smaller AI model, the "student." Although it's often used legitimately within companies using one of their own AI models to train another, it's also a practice that's sometimes used by smaller AI labs to try to get their models to mimic the performance of a larger competitor's model. Asked on the...

A recent paper published in *JMIR Mental Health* (Csigó & Cserey, 2026) caught my attention. The researchers administered the 10 standard Rorschach inkblot cards to three multimodal LLMs (GPT-4o, Grok 3, Gemini 2.0) and coded their responses using the Exner Comprehensive System. They analyzed the models' "perceptual styles," determinants (like human movement vs. color), and human-related content themes. However, I am seriously struggling to understand the methodological validity of this setup, and I’m curious what the scientific community thinks. My main concerns are: Massive Data Cont...
