GPT-6.1 Terra is now a Codex model on ChatGPT Plus and all three Pro tiers: the Codex pricing page publishes a Plus / Standard Business row of 35-285 local messages per 5h and a credits-per-1M row of 25 input / 1.25 cached input / 125 output, and the Codex models page documents it as live in Codex (gpt-6.1-terra, Codex CLI 0.159.0 or later). It joins Plus, Pro 100, Pro 200 and Pro 500 after GPT-6.1 Sol — Plus 7 -> 8 models, each Pro tier 8 -> 9 — while Go is unchanged at GPT-6 Luna (the estimate table has no Go column). Recorded, not papered over: the chatgpt.com/pricing “Compare features across plans” matrix has zero occurrences of “GPT-6.1 Terra” (it still lists GPT-5.6 Terra as “Limited access in Work and Codex on desktop” on Free/Go and Yes on Plus), while developers.openai.com/codex/pricing — the plan records’ own source — publishes the 35-285 row, so the Codex page wins and every GPT-5.6 row stays exactly as stored. Prices re-read unchanged: Go $8, Plus $20, Pro from $100 with tiers $100/$200/$500 — the €8/€23/€103 figures on the rendered chatgpt.com page are VAT-inclusive localized display, not a price change.
