Anthropic announced a 'public benefit fund,' a wholly-owned entity that will initially hold 5% of the company's shares, with an option to add 2% more for every 50% increase in Anthropic's valuation. The company said the fund could support large nonprofit donations or direct payments to specific populations, and pointed to AI's effect on jobs as one area it might address, alongside its existing $200 million research commitment on that topic. Anthropic said details on the fund's structure and governance will be released in coming months.
Anthropic has given METR, a nonprofit AI safety evaluator, 'employee-like access' to its hardware and internal systems, embedding a team inside its offices to assess risks from its Claude models. The move fulfils a commitment CEO Dario Amodei made in September, when OpenAI's Sam Altman and Elon Musk backed his call for third-party auditors inside leading AI labs. OpenAI has not yet announced similar arrangements.
Anthropic is pushing federal lawmakers to adopt a bill that would let the Commerce Department block an AI model's release only if it risks causing more than $1 billion in damages or killing or injuring over 50 people, according to Politico. The bill would require a Commerce-registered independent evaluator to periodically assess labs and models, report imminent risks within 72 hours, and have a federal judge in Washington, D.C. decide whether to halt a release, with no other federal agency empowered to intervene.
Anthropic published an internal report Friday showing its workforce has shifted over the past year, with junior employees in technical roles falling from 21% to 14%, and junior technical hires dropping from 27% to 9%. The company also said technical staff now make up 56% of its workforce, down from 61%, as non-technical employees increasingly use coding tools to build software themselves. A survey cited in the report found 27% of employees felt more productive due to Claude, while 20% said their work had shifted from doing tasks to overseeing Claude's output.
Replit CEO Amjad Masad said at TechCrunch Disrupt that OpenAI's models are now the default for Replit Agent, replacing Anthropic's Claude as the primary choice. He cited cost, partnership terms, and performance on internal benchmarks as reasons, though Masad says Anthropic's Claude remains available for users who choose it.
OpenCode said it suffered a security breach described as a large-scale distillation attack, which affected 1.4% of its Console users. The company notified affected users by email and says the incident is still ongoing, so further details are not yet available. OpenCode stated it is working with Anthropic, OpenAI, and Google to address the issue.
Contexte Tech's Tony argues that the Model Context Protocol (MCP), launched by Anthropic in November 2024, is increasingly used by AI assistants like Claude, ChatGPT and Cursor to fetch live answers directly from publishers' own servers rather than relying on frozen training data. The protocol was transferred in December 2025 to the Agentic AI Foundation, part of the Linux Foundation, and has progressed through several dated versions, with a public registry now listing available servers.
Anthropic told private investors its revenue grew 45 percent to nearly $17 billion, according to the Wall Street Journal. Critics and some investors say that figure falls far short of what's needed to justify the company's anticipated $2 trillion valuation, with Reuters reporting some investors are now considering a lower valuation of roughly $1.5 trillion.
Speaking at TechCrunch Disrupt, Replit CEO Amjad Masad said the coding platform is no longer working with Anthropic, citing cost, partnership terms and performance as reasons. He said OpenAI's models now outperform on Replit's internal and public benchmarks for building apps from scratch, following the company's August partnership announcement with OpenAI.
Anthropic's Claude Code team published an account of how it adapted code review practices as AI-generated code volume surged. Merged pull requests to the Claude Code repository more than doubled between June and September, while the share of PRs later reverted fell by over 40%. The team says it shifted most initial code reading to automated Claude-based checks that run continuously, reserving human review for higher-level judgment calls.
Anthropic reports that its Claude model, given plain-language specs for eight quantum circuits spanning chemistry, optimization, physics simulation and number theory plus an automated scoring evaluator, independently produced designs that outperform the best previously published circuits, in some cases by more than tenfold. The work was led by Andi Gu through Anthropic's STEM Fellows Program, with mentorship from quantum physicist Alek Kemeny and collaborators from Harvard University and QuEra Computing.
Anthropic said it will give six evaluators from third-party nonprofit METR hardware, office space and internal system access comparable to its own risk-assessment teams, excluding items like customer data or model architecture details. METR will independently publish its safety findings on Anthropic's models, and Anthropic says it cannot withhold any of those conclusions, though it may request redactions of sensitive material.
