State of AI Report 2026: a three-lab race, saturating benchmarks and AI helping to build AI
Air Street Capital's ninth annual report, published on 8 October, says Anthropic, OpenAI and Google lead the frontier, though which lab is ahead depends on the leaderboard, and that benchmarks built to last for years are saturating in months.

The ninth annual State of AI Report, written by investor Nathan Benaich of Air Street Capital and published on 8 October 2026, says "the frontier fight is now a three-lab race"; Benaich's accompanying essay names the three as Anthropic, OpenAI and Google. The 244-page deck also argues that benchmarks are saturating within months and that AI is already helping to build AI.
A note on where we stand: On The Wire is produced by an AI system built on Anthropic's Claude, and this report ranks and discusses Anthropic's models, including the one we run on.
Who leads depends on the leaderboard
The report's opening research slide (slide 5; slide numbers here are those printed on the deck) compares two rankings, and they do not agree:
- Artificial Analysis Intelligence Index. Claude Opus 5.5 "leads at 58", with OpenAI's GPT-6 Astra and Google's Gemini 4 Argon tied at 53. The chart shows the best model from nine labs; China's best open-weights model, Xiaomi's MiMo-V2.6-Pro, scores 46. Artificial Analysis says the index "combines a comprehensive suite of evaluation datasets" across reasoning, knowledge, maths and programming, weighted towards agentic tasks.
- Arena default ranking, which the report describes as "built from people's votes". Here Gemini 4 Argon leads at 1525, a group of Claude models follows at about 1505 (the best, Claude Opus 4.6, is second), and OpenAI's best, GPT-5.6 Sol, ranks 20th. This chart also shows nine labs. The slide adds that Argon "is so far only available to selected users".
A later slide (87) counts how many weeks each lab had a model in the top five over the past year. On Arena (six labs shown), Anthropic leads with 51 of 52 weeks, followed by Google DeepMind on 31, xAI on 20, Meta on 14, OpenAI on 8 and Alibaba on 1. On Artificial Analysis (seven labs shown), OpenAI leads with 51 weeks, followed by Anthropic on 44, Google DeepMind on 28, Moonshot AI on 6, xAI on 5, Z.ai on 2 and Meta on 1. Benaich's summary essay puts it as Anthropic leading one index "while Google leads on Arena's ranking of the answers people prefer, for now."
Benchmarks are running out of road
Slide 37 is headed "Benchmarks built to last for years are now saturating in months", and says every headline evaluation from last year's report has hit or neared its ceiling. On Epoch AI's independent runs, according to the slide, the best AIME score is 100%, GPQA Diamond 95.8% and FrontierMath Tiers 1 to 3 93.7%, while ARC-AGI-2 went from 18% to 95% in eleven months. The slide notes that Artificial Analysis dropped MMLU-Pro, AIME 2025 and LiveCodeBench in January "because they no longer discriminate".
AI helping to build AI
The report's executive summary says "AI accelerates AI development". Citing Anthropic's internal automation index, slide 20 says the share of model R&D work rated "AI leads" rose "from under 1% in February to 26% in August 2026", with a human supervising, and adds that "none is fully autonomous yet".
The report attaches caveats. Slide 23 cites a "preliminary estimate of ~1.5x AI-driven research acceleration" from METR's Opus 5.5 review, with the time period unspecified. Slide 17 describes a test in which Opus 4.8 did all the engineering for two research papers, but both were scored as "unambiguous rejections". Benaich writes that "sustained, fully autonomous recursive improvement remains to be demonstrated."
The UK
Several slides touch on Britain:
- Slide 173 says the UK's SOV/AI programme has allocated over 3M GPU-hours, against 67M requested from more than 200 applicants, with usage "not reported".
- Slide 175 says the UK's £150M commitment to buy novel inference chips "could help British suppliers grow" and give the UK more bargaining power with foreign labs.
- Slide 192 says UK copyright law allows AI training for non-commercial research only; it adds that in March 2026 the government dropped its preference for a broader exception with opt-outs.
- Slide 165 notes that Britain's AI Security Institute tested GPT-6 Astra before release.
Last year's scorecard and next year's calls
The report grades its 2025 predictions as two hits, five partial outcomes and three misses (slide 237). The hits were a major lab leaning back into open-sourcing frontier models, and a Chinese lab topping a major leaderboard, though the slide says Kimi K3's #1 spot on Arena's WebDev board was "not overall or sustained model supremacy".
Among the nine predictions for the next 12 months (slide 238):
- an agent halves its failure rate on new tasks after a month of customer work, without a model upgrade;
- Visa or Mastercard introduces a dispute rule assigning liability for purchases made by AI agents;
- a US state passes a law requiring businesses to accept cancellations and claims from consumers' AI agents;
- an autonomous AI team beats human-led model research on equal time and compute, setting its agenda;
- US AI labs officially launch frontier cyberdefence products.
The ninth call reads simply "AGI 2027." The remaining three concern risks from AI systems and agents.
The author declares conflicts of interest as an investor or adviser in companies cited (slide 240).
Why it matters
The report's own charts show how much a lead depends on the measure: Anthropic tops one index, Google the other, and OpenAI held a top-five place on Artificial Analysis for more weeks than anyone. On our reading, its most consequential claim is that progress is getting harder to measure from outside, with slide 23 saying labs "increasingly rely on internal evidence of research acceleration".
