btibor91's week-44 roundup of OpenAI and Anthropic news: GPT-6.1 Terra, a fast computer-use model, launches in ChatGPT Work, Codex and the API at prices 50% below GPT-5.6 Terra; GPT-6 Rosalind Research brings GPT-6 reasoning to life sciences with biological safeguards, rolling out to approved Research customers only. GPT-6 in Chat gets more concise, less flattering responses for Free/Go/logged-out users, and the Model Spec is reorganized around five values. Starting December, Plus/Pro/Business usage allowances will be shared across ChatGPT and Codex, measured in tokens. Plus: three internal-model discoveries in math/CS/physics, iCloud plugins, iMessage/RCS texting preview, and up to $500/month in API credits for Pro and Business.
