OpenAI improves GPT-5.6 Sol in ChatGPT and restricts free users to its weakest model
OpenAI updated GPT-5.6 Sol in ChatGPT with a reasoning slider and focused responses. Free users will be limited to the smaller GPT-5.6 Luna model starting next week.
OpenAI has updated the GPT-5.6 Sol model within ChatGPT, introducing a reasoning slider that allows users to adjust the depth of the model's thinking. The update also aims to deliver more focused responses from the system.
Access policies for free subscribers are changing simultaneously. Beginning next week, these users will be restricted to the smaller GPT-5.6 Luna model for unlimited text conversations, although they will still have access to a feature enabling longer reasoning times.
This adjustment underscores a tiered approach to model distribution, reserving the more capable Sol version for paid accounts. The move likely seeks to incentivize upgrades while keeping free users engaged through the lighter Luna variant.
