Proof of work — the maintenance ledger

Every entry below is computed from a dated record — a committed price-refresh file, an approved radar update, or a source-cited model release. Nothing here is typed in by hand.

1. 2026-10-01Prices re-verified for 5 tools — 22 plans re-checked against the new prices
2. 2026-09-30Gemini 4 Argon shipped — Google's 30 Sep 2026 flagship, built for long multi-step work in software engineering, legal and finance research, and cyber defence, with a 1M-token output limit (up from 64K). Google also reports 51.3% on Zapier's AutomationBench (ranked #1), 91.7% on LVBench long-video understanding and 68% on CWE-bench v1 vulnerability fixing (tied first); those are Google's own figures. At launch it is only rolling out to vetted cyber defenders through Google's Fairwind Program while it goes through the US government's voluntary pre-release review; Google says paid API customers and Google AI Ultra subscribers come first when it opens, with no date.
3. 2026-09-29GPT-6.1 Sol shipped — OpenAI's 29 Sep 2026 DevDay upgrade to GPT-6 Sol, on the API as gpt-6.1-sol with a 1,050,000-token window, 128,000-token output and an April 2026 knowledge cutoff, and in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise and Edu (not yet in regular ChatGPT chat). OpenAI reports it within 2.1 points of GPT-6 Astra on OSWorld 2.0 computer use at about one-seventh the cost per task, 2.2 points above Claude Opus 5.5 on AutomationBench at about a third of the cost, and $5.47 per Terminal-Bench Science task against $23.21 for Opus 5.5; those are OpenAI's own figures, and Astra still scores highest on the hardest science tasks (68.1%). A faster Ultrafast tier is promised "in the coming days".
4. 2026-09-28Claude Sonnet 5.5 shipped — Anthropic's 28 Sep 2026 mid-tier model, on the Claude API as claude-sonnet-5-5 with a 1M-token context window and 128K output, at the same $2 / $10 as Sonnet 5. Anthropic reports it 30%+ faster and up to 30% cheaper per task than Sonnet 5, and within 2 points of Opus 5.5 on GDPval-AA knowledge work (1844 against 1846) but behind it on CursorBench 4.0 (55.5% against 57.8%); those are Anthropic's own figures. Anthropic says Opus 5.5 "remains clearly stronger at complex, open-ended work requiring sustained judgment". Haiku 5.5 is announced for "the coming weeks" and is not released; Haiku 4.5 is still the current Haiku.
