What happened
On July 9, 2026, OpenAI released GPT-5.6, its newest set of AI models. The family has three tiers. Sol is the most capable. Terra sits in the middle. Luna is the fastest and cheapest. All three work in ChatGPT and through OpenAI's API. An API is the pipe that lets other apps plug into a model.
The context
GPT-5.6 follows OpenAI's earlier GPT-5 line. It is the company's main answer to rival models from Anthropic and Google.
