Newer GPT-5-family releases, including GPT-5.2, have shipped; this profile remains specific to GPT-5.1

The OnAirToday AI Progress Tracker recorded a verified change to OpenAI's GPT-5.1 (version gpt-5.1): Newer GPT-5-family releases, including GPT-5.2, have shipped; this profile remains specific to GPT-5.1.

GPT-5.1 is an OpenAI reasoning model supporting text and image inputs, text output, and tool-assisted workflows. Its documented improvements emphasize adaptive reasoning, lower-latency interactions, and coding, while newer GPT-5-family releases have subsequently shipped.

What changed in this review:

• Benchmark coverage now distinguishes OpenAI's published evaluation results from third-party figures.
• OpenAI reports GPQA Diamond at 88.1%, SWE-bench Verified at 76.3%, and AIME 2025 at 94.0%.
• Unconfirmed benchmark figures and Elo ratings without a documented 0–100 conversion are excluded.
• Sandbox-escape and Hugging Face breach reports are listed separately at family level, without attributing either to GPT-5.1.
• Pricing remains $1.25 per million input tokens and $10 per million output tokens for standard API usage.
• Flaws and limitations updated

Teams building on GPT-5.1 should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.

The full profile — capabilities, benchmark citations, known flaws and risk guidance — is on the tracker at /ai-models/gpt-5-1.
