Revision History

Improve internal links (2026-10-13)

Correction: the page did not mention Ultrafast, the premium speed tier OpenAI added for GPT-6 Astra on September 29, 2026 and the only model it covers. Added a sourced paragraph with the API prices, rate limits, speed claims and ChatGPT usage multipliers, plus five sources.

Update: added the September 29 "Appendix: dots" system card change-log entry, the GPT-6.1 Sol launch, the reported cancellation of GPT-6.1 Astra, and the 68.1% Terminal-Bench Science figure OpenAI later gave for Astra

Update: OpenAI's 21 Sep 2026 Advisory Group announcement and its claim of 100+ open problems resolved by its internal model

Minor: removed speculation about why OpenAI's three honeypot figures differ; the card's stacked Figure 9 bar separates successful attacks, attempted attacks and legitimate exploits

Minor: note that the card's own Figure 9 labels Sol's honeypot bar 56.0% while its text says 55.4%; deception figures located in the card's Figures 10 and 11

Minor: the launch post still shows the pre-revision HealthBench 63.4% after the system card was revised

Correction: GPT-6 Sol and Luna released Sept 22 (no-variants sentences dated); system card HealthBench values for Astra revised Sept 22; updated alignment evals noted

Verification fixes: BenchCAD sample-size context; OSWorld footnote quote updated (OpenAI reworded it after launch; launch-day wording noted)

Add OpenAI's own BenchCAD description (3D reconstruction from multi-view renders via CAD code) and cost note, The New Stack's Vision2Code-subset detail, and the 'visual judgment ... renderings' line; link inverse_graphics

Auto-saved before update

Added the launch post's mid-task steering description and the September 4 OpenAI Developers video post to the Codex section

Link Claude Fable 5.1 and Claude Mythos 5.1 to their new pages

Correction: internal ExploitBench (June-August 2026) Sol figure is 11.5% (launch-day table cell read 5.5% against the post's own chart); Fast-mode speed and Bedrock wording changes on the live post noted
