Anthropic, the AI lab valued at $380 billion, has acknowledged that a series of engineering missteps were behind a widely-experienced decline in the performance of its Claude Code tool that sparked a user revolt over the past month. The latest admission, which came after weeks in which Anthropic had initially implied in its communications that nothing was wrong and that users were largely to blame for any performance problems and later said some of the changes had been made for users’ benefit, has done little to calm Anthropic’s customers—some of whom say they have already cancelled their su...

Chinese AI company DeepSeek released a preview of its hotly anticipated next-generation AI model V4 on Friday, saying that the open-source model can compete with leading closed-source systems from US rivals including Anthropic, Google, and OpenAI. DeepSeek says V4 marks a major improvement over prior models, especially in coding, a capability that has become central to AI agents and helped drive the success of tools like ChatGPT Codex and Claude Code. The release is also a milestone for China's chip industry, with DeepSeek explicitly highlighting compatibility with domestic Huawei technology....

I benchmarked and compared Claude Opus 4.5 vs Opus 4.6 vs Opus 4.7 vs Sonnet 4.6 testing effort levels from low, medium, high, xhigh, max as curious about token usage/costs and performance within Claude Code https://ai.georgeliu.com/p/tested-claude-ai-llm-models-effort Hope folks find this useful. The test was done with Claude Code v2.1.117 which is apparently the fixed versions from Anthropic's post-mortem announcement.

Claude users can access more apps with Anthropic's AI now thanks to new connectors for everything from hiking to grocery shopping. Anthropic already supported connecting numerous work-related apps to Claude, like Microsoft apps, but this expansion focuses on personal apps like Audible, Spotify, Uber, AllTrails, TripAdvisor, Instacart, TurboTax, and others. Some of these apps, such as Spotify, already have similar connectors in OpenAI's ChatGPT. Once an app is connected, Claude will suggest relevant connected apps directly in your conversations, like using AllTrails for hike recommendations. A...

Anthropic's tightly controlled rollout of Claude Mythos has taken an awkward turn. After spending weeks insisting the AI model is so capable at cybersecurity that it is too dangerous to release publicly, it appears the model fell into the wrong hands anyway. According to Bloomberg, a "small group of unauthorized users" has had access to Mythos - whose existence was first revealed in a leak - since the day Anthropic announced plans to offer it to a select group of companies for testing. Anthropic says it is investigating. That's a rough look for a company that has built its brand on taking AI ...

User observes API rate-limit reset time shifted from Thursday to Saturday; speculates new model launch.

The AI model that Anthropic billed as too dangerous to release has reportedly been accessed by an unauthorized third party, and the incident raises concerns about the future of cybersecurity. The Mythos model was reportedly accessed by a handful of users in a private Discord chat on the day it was announced publicly, Bloomberg reported. Earlier this month, the group was able to access the program in part because one of the members of the group is a third party contractor for Anthropic, according to Bloomberg. Using this access, the group was able to guess where the model was located based ...

He said it on the [Dwarkesh Podcast ](https://mrkt30.com/anthropic-mythos-triggers-chinas-ai-arms-frenzy/)this week and I have not been able to stop thinking about it. His argument was not that China is not a threat. It was that cutting them off and treating them as an enemy is probably not the smartest long term play. His actual words were that victimising them and turning them into an enemy likely is not the best answer. The context here is Huawei targeting 750,000 AI chip shipments this year. It is nowhere near Nvidia's compute but the direction of travel is clear. And if DeepSeek ends u...
