GPT-5.6
Launched this week
GPT-5.6 is rolling out in the API!
Our new family of models gives builders three options: Sol (our flagship model for the hardest agentic tasks), Terra (balanced for everyday workflows), and Luna (fast and cost-efficient). GPT-5.6 also introduces Programmatic Tool Calling, Multi-agent (beta) for parallel execution, and explicit prompt caching.
On July 23, we're teaming up with Product Hunt for OpenAI Day. The top five launches will each receive $10K in API credits.

Curious how the pricing scales for smaller teams just starting out with API access, especially compared to self-hosting open-weight models.
Does it automatically perform semantic compression during preprocessing to reduce input token usage?
the docs are genuinely well organized, and getting a working prototype running over the weekend was way faster than i expected.
The API documentation is genuinely some of the best I've worked with, clear examples that actually run and sensible defaults that save hours of trial and error.
How does it compare to Fable 5?

GPT is backk
The API docs are genuinely some of the cleanest I've read, with code samples that actually work on the first try. Really impressive that a tool this complex still feels approachable.
