OpenAI, Anthropic and Google Cloud publish different minimum notice periods for retiring AI models; the Herald's date arithmetic puts GitHub Copilot's notices at 31 to 32 days, and one OpenAI notice ran about three months.

OpenAI's November 4 API release adds a complexity setting, SVG and GIF output and markup edits; the API reference says GIF requires preview access, the 2.6 pages list Batch as not supported, and gpt-image-2 is deprecated for removal on February 10, 2027.

OpenAI said on November 4 it will acquire Pierre Computer, maker of Code Storage and the Trees and Diffs libraries used in Codex; terms were not disclosed and closing needs regulatory approvals.

Four recent releases place limits on model use in different layers: a product prompt, API-side safeguards, account-level access programs and staged rollouts. Reports attribute the key figures to the vendors.

OpenAI's API changelog says developers can now choose 12-hour prompt caching; its guide lists a 2.5x cache-write rate against 1.25x for the 30-minute default.

OpenAI and Anthropic list one model at several per-token rates by speed, OpenAI prices GPT-6.1 Sol at a fifth of Astra, and Red Hat reportedly caps developer token spend.

OpenAI's changelog lists prompt-to-voice for all API customers on October 16 and native Decisions integration in GPT-Live on October 15, plus nine new voices.

OpenAI's Codex CLI 0.163.0 adds a searchable /config, follow-up steering during a response, a configurable leader key and parallel read-only tools, plus network proxy and thread-resume permission fixes.

OpenAI's changelog says GPT-6.1 Sol gained an Ultrafast service tier on Oct 8; its pricing page lists $12 input and $60 output per million tokens, six times Standard.

OpenAI's API changelog says it cut usage tiers from five to three on October 6. Its rate-limits guide lists monthly usage limits of $500, $5,000 and $200,000.

OpenAI's Decisions API, in beta since October 6, returns probabilities, choices and scores from gpt-6-luna; OpenAI lists input at $0.10 per 1M tokens.

OpenAI's Codex 0.162.0 adds worktree tools, task pinning and clickable URLs, plus sandbox fixes; 0.161.0 a day earlier made GPT-6.1 Sol the default model.
