1/4 METR published an independent assessment of AI R&D acceleration at Anthropic (Nov 5). Its estimate: capabilities on well-specified tasks are improving at about 2x the Mar 2024-Oct 2025 rate, with high uncertainty (1.3x to 3x plausible). The evaluation ran Aug 12-Oct 29.
3/4 Limits: Anthropic redacted most of the evidence METR found most informative, so the public "has to rely on METR's judgment." Staff Slack polls reached 12x self-reported speedup, which METR calls loose evidence. It saw no clear bottlenecks, but its view changed several times.
Anthropic studied 207,049 research sessions on Claude plans. Data analysis was 48.1% of Claude Code sessions vs 27.6% of researcher time; data gathering was 11.9% vs 28.6%. Use skews toward tasks Claude is rated most capable at. Consumer plans only; correlational.

Village's LLM Atlas says an open-weight model is the best buy at only 3% of price points as of Oct 31, down from 41% in June. It tests 201 budgets from 1% to 3x GPT-5's cost per task. Its lowest reading since the series starts in 2024.

Village says open models win in bursts: single releases drive peaks, like DeepSeek-V3.2-Exp in Sept 2025, then the open share falls by about half or more by the next quarter. Its reasons (distillation, full model families, serving scale) are proposed explanations.

Ricursive released Ripple-65B Preview on Nov 4: a dense 65B model pretrained on 12T tokens, up to 1M context, Apache-2.0 weights on Hugging Face. It reports 80.52 on TerminalBench 2.1, ahead of Reflection Beam 501B (80.1) and Meta Muse Spark Open 816B (76.4).
3/4
Cost, per Ricursive: $32M total R&D, which it estimates is one-tenth of the prior open-weight leader. RL took 1.4M rollouts, "roughly 70x fewer" than Reflection Beam. The comparison rests on reported Reflection compute spend, not audited figures.
Anthropic's FlashProve prototype uses a zkSNARK to prove a response came from a committed model without revealing weights.
On Llama 4 Maverick, proving takes ~72x vLLM's GPU time, proofs are ~19 MB, and context is capped at 1,024 tokens. Verifiable, but not cheap.

MIT CSAIL's weight-programming post says GPT-6 Astra can tell what a network does "just by looking at the raw weights." Matthew Honnibal, spaCy's author, says that no-tools setting covers only experiments 1, 2 and 4, on networks of 17K-172K weights.

Simon Willison ran the no-tools game-ID prompts on Qwen 3.8 27B (17GB, laptop). It named Breakout, Pong and a Pac-Man-style game, and missed Freeway. Answers took 46 to 65 minutes each. One run per game, no statistics. He called the traces "almost incomprehensible."
