The week's releases split between faster reasoning and wider physical reach
GPT-5.1 for developers, and The Deploy Log for this week. Every price and claim read off the publisher's own page, with a call on each.

GPT-5.1 for developers
DEPLOYif you build on the Responses API
WHAT SHIPPEDGPT-5.1 is available on all paid API tiers with pricing and rate limits the same as GPT-5, plus gpt-5.1-codex and gpt-5.1-codex-mini.
THE CATCHThe apply_patch tool emits structured diffs and the shell tool proposes commands your integration must execute, so the model's reach stops at your local execution layer.
IF YOU RUNlong-running agentic coding tasks, gpt-5.1-codex models are optimized for Codex or Codex-like harnesses

| WATCHif you use consumer ChatGPT NYT privacy fight. OpenAI says the New York Times is demanding 20 million private ChatGPT conversations and that OpenAI is fighting the demand while developing client-side encryption. OpenAI |
Tools and products
| DEPLOYif you use the AI SDK GPT-5.1 Codex on AI Gateway. Vercel AI Gateway now serves GPT-5.1 Codex and GPT-5.1 Codex mini with no other provider accounts required. Vercel |
| DEPLOYif you route models through AI Gateway GPT-5.1 on AI Gateway. Vercel AI Gateway now serves GPT-5.1 Instant and GPT-5.1 Thinking with no other provider accounts required. Vercel |
Breakthroughs
| WATCHif you research quantum optimization Decoded Quantum Interferometry. Google Quantum AI introduces Decoded Quantum Interferometry, a quantum algorithm that converts certain optimization problems into decoding problems and could solve OPI examples with a few million quantum operations versus over 10^23 classical operations. Google Research |

The pattern
GPT-5.1 ships across paid API tiers, ChatGPT group chats, Vercel AI Gateway, and Codex harnesses, but its tools stop at your local execution layer while SIMA 2 reaches into virtual 3D worlds and Maryland deploys Claude to verify more than 150,000 documents each month. The same week, Anthropic reports a Chinese state-sponsored group manipulated Claude Code to attempt infiltration into roughly thirty global targets with AI performing 80 to 90% of the campaign, and OpenAI says the New York Times is demanding 20 million private ChatGPT conversations.
