ChatGPT has become so much more than just chat over the last year. To that end, OpenAI is removing limits on text chat. ChatGPT will also improve with a smarter version of GPT-5.6 Sol. Details below.
GPT-5.6 Sol gets smarter in ChatGPT
OpenAI introduced GPT-5.6 Sol in June as the flagship member of a three-model family. Sol, Terra, and Luna became widely available in ChatGPT and Codex the following month.
Now OpenAI is releasing a version of GPT-5.6 Sol tuned specifically for everyday conversations in ChatGPT. The company says the update should produce more focused answers, adapt the level of detail to each question, and avoid unnecessary formatting.
