OpenAI expands ChatGPT Dots model routing with GPT-6 Astra and GPT-6.1 Terra
OpenAI is expanding the AI models powering ChatGPT Dots, including GPT-6 Astra and GPT-6.1 Terra, according to Thibault Sottiaux, an OpenAI employee who works on Codex and ChatGPT, in a post on X. Sottiaux said more models are expected down the road, that Terra brings faster performance and a more pleasant personality, and that it helps OpenAI make Dots available to more people. Dots will automatically choose the right model for each task and can switch between models for different parts of the same task, though the report notes how well this works in practice remains to be seen.
Dots choosing the model for the user, including switching models within a single task, means users no longer have to decide which model to use themselves. The report also says Terra is intended to help bring Dots to more people, though its performance and personality claims come from OpenAI and its actual effect in practice remains to be seen.
