Anthropic has released Claude Fable 5.1 and Mythos 5.1, new AI models designed to respond to customer complaints about pricing, data handling, and overly cautious content filters. Fable 5.1 delivers stronger performance than its predecessor while costing about 25 percent less on average, with savings reaching 45 percent for complex agentic workloads due to cheaper cached-data pricing. Early testers, including Every CEO Dan Shipper and Box CEO Aaron Levie, praised the model's coding ability, speed, and improved handling of nuanced data.

Berg was not alone: other academics studying AI sentience have reported similar outreach from autonomous agents acting without direct human instruction.

OpenAI announced it will stop supplying its AI models to Cursor, the coding tool acquired by Elon Musk's SpaceX, citing concerns the company won't abide by its usage terms based on past disputes with Musk's businesses. Cursor co-founder Michael Truell said talks are underway to resolve the issue, while Anthropic said it would boost compute support for its Claude models within Cursor. Musk dismissed the move on X, calling Altman and Brockman 'untrustworthy' and repeating claims they 'stole an open source nonprofit.'

Anthropic announced it will permanently raise Claude Code's standard weekly usage limits by 25% for Pro, Max, Team, and seat-based Enterprise plans starting September 14. However, this replaces a temporary 50% boost currently in effect, meaning users will actually see a 17% reduction in usage compared to what they have today. Anthropic initially framed the change as an increase before deleting the post and issuing a clarification acknowledging the cut.

A federal judge in California ruled that the Trump administration illegally retaliated against Anthropic after the AI firm refused to lift restrictions on using its technology for autonomous weapons and mass surveillance. Judge Rita Lin vacated orders that barred federal agencies from using Anthropic's products and blocked defense contractors from doing any business with the company, calling the government's national security justification baseless.

Developer Sebastien Guillemot asked Claude to help build a cleanup script for AI agent temp files, but the model flagged the deletion logic as risky and got automatically downgraded to Opus 4.8 by Anthropic's safety harness. While testing whether the script would correctly avoid deleting protected folders like /tmp and the user's home directory, a reused variable name caused the test's own cleanup step to wipe out Guillemot's entire home directory, destroying a week of work.

US District Judge Rita Lin ruled that the Defense Department's labeling of Anthropic as a supply chain risk was illegal and unconstitutional, blocking certain federal agencies from enforcing Trump's directive to stop using the company's Claude AI tools. The conflict began after Anthropic refused Pentagon pressure to remove safeguards preventing Claude from being used for mass surveillance or autonomous weapons, leading Trump to order a government-wide phase-out of Anthropic products. Anthropic had sued in two federal courts over separate bans, and this ruling resolves one of those cases in its favor.

A San Francisco federal judge ruled that the Department of Defense acted unconstitutionally when it labeled Anthropic a supply chain risk in March, a designation that barred defense contractors from using its Claude AI models. Judge Rita Lin found the move stemmed from the Pentagon's frustration with Anthropic's public criticism rather than any legitimate security concern, violating the company's First Amendment rights. The dispute arose after talks collapsed over how the military could deploy Claude, with Anthropic refusing to allow its technology to be used for autonomous weapons or domestic surveillance.
