METR: Anthropic is accelerating capability progress about 2×, largely with AI doing R&D

METR published on Thursday (11/05) an independent high-access assessment of Anthropic (08/12 to 10/29/2026) on whether AI is accelerating AI research itself. The team's subjective conclusion: in October 2026 Anthropic is probably improving capabilities on well-specified tasks at about twice the pace of March/2024–October/2025 (with uncertainty; the plausible range cited runs from about 1.3× to 3×). On AECI scores (Anthropic's version of the Epoch Capabilities Index), the acceleration since October/2025 is about 1.9× (95% CI: 1.5–2.8×). METR says it is confident the acceleration did not come from speeding up training-compute scaling, and estimates (with high uncertainty) that a majority — perhaps ≈80% — of the current acceleration comes from using AI in R&D. Anthropic redacted much of the most informative evidence. Final public report submitted on 11/03; METR's X post had about 168 thousand views and 1,537 likes around 6:10 p.m. Brasília on 11/05.

OpenAI publishes National Community Compact and a policy blueprint for compute campuses

OpenAI launched the National Community Compact (voluntary commitments at campuses it operates) and a Compute Campus Policy Blueprint for lawmakers. At future campuses: pay for energy and infrastructure in full, with financial guarantees before large spend; a water plan and public reports on water/electricity/noise; no NDAs with public authorities (except security/narrow trade secrets); and local investments. The blueprint asks utility commissions to make large consumers cover costs and protect other customers. CNBC links the announcement to electoral backlash against data centers.

Anthropic launches Personal Finance in Claude (US beta): banks and cards via Plaid, read-only

Claude gets Personal Finance in beta on Pro, Max and Ultra plans in the US: the user connects bank accounts and cards through Plaid (bank login; Anthropic does not see the password). Access is read-only — it does not move, manage or invest money; there are no ads and no Anthropic credit/loan product. Claude sees bank name, type/last 4 digits, balances/limits and up to 2 years of transactions; conversations in the Personal Finance hub do not train models. TechCrunch and The Verge covered the launch the same day.

Viral Boris Cherny clip: “I stopped prompting agents; I build graphs and loops”

A post quoting Claude Code creator Boris Cherny — “I've stopped prompting my agents. I build graphs and loops now…” — had about 10 thousand views and 117 likes, and echoes Thursday's “harness/graph engineering” trend on X. The clip reinforces the thesis that the product now is the system around the model, not the prompt.
