OpenAI adds GPT-6.1 Terra model to ChatGPT and Codex
OpenAI has upgraded Terra, the mid-tier model left out when the company released GPT-6 Sol and Luna last month, from GPT-5.6 to GPT-6.1. The company says the new version is faster, improves computer use capabilities and comes at a lower price. The update is now live in ChatGPT and Codex.
