testingcatalog · x · 2026-10-20
GPT-6.1 Terra has appeared in a Microsoft pull request, with 18 eval configs renamed from GPT-5.6 Terra. It aligns with The Information's report of a new cheaper-than-Sol Terra model as OpenAI competes with Anthropic on price (Sol: $2/M input, $10/M output). A busy month of releases is expected, including a new Anthropic model and Gemini 4 Carbon. Unconfirmed by OpenAI.
