'GPT 6.1 Terra' release post with Agents' Last Exam chart looks like a parody

whoiskatrin · x · 2026-10-27

A post claims 'GPT 6.1 Terra' is out with stronger agents at a fraction of the cost, across ChatGPT, Codex and the API, attaching an OpenAI-style 'Agents' Last Exam v1' cost-vs-score chart. The chart lists clearly nonexistent models — GPT-6.1 Terra, GPT-6.1 Sol, GPT-5.6 Terra, GPT-6 Astra, GPT-6 Luna, even Claude Opus 5.5 — making the whole thing look like a parody or fictional future release rather than a real announcement.
