OpenAI's GPT-6 Astra scores 80% on Epoch AI's furniture assembly benchmark

Epoch AI's Furniture Assembly Benchmark (FAB) tests models on identifying deliberate assembly errors in photos of IKEA furniture. Previously the best model (Claude Opus 4.5) scored 28% in November 2025; ten months later OpenAI's GPT-6 Astra reaches 80% with a processing time of about three minutes per photo, followed by Claude Fable 5.1 at 70% and Claude Opus 5 at 61%, while some Chinese open-weight models like Kimi K3 lag substantially.

Epoch AI: cost to reach fixed benchmark scores fell ~47% per quarter; MIT finds smaller algorithmic gains (~3x/yr)

Epoch AI reports that market prices to achieve fixed scores on five AI benchmarks fell about 47% per quarter (≈13x/year) since 2023, citing examples like OpenAI's o3 vs GPT-5.6; the group warns its sample is limited and measures market price per benchmark score rather than pure algorithmic progress. MIT researchers (Hans Gundlach et al.) using broader model pricing data find 5–10x annual declines in benchmark cost but estimate actual algorithmic efficiency gains of ~3x/year after removing hardware and competition effects, and note some improvements come from higher test‑time compute rather than efficiency.

Daily AI usage in US more than doubled from March to August 2026

Epoch AI, with polling partner Ipsos, ran representative US surveys in March and August 2026 and found the share of adults using AI at least six days a week rose from 8% to 19%; occasional (one-day-per-week) users fell from 17% to 10%. The March sample had 2,017 respondents and the August sample 1,016, and Epoch AI cautions the two estimates are not fully comparable because question wording differed between surveys.
