OpenAI today launched a constricted preview of its GPT–5.6 series, which includes flagship exemplary Sol, a balanced mundane enactment exemplary named Terra, and Luna, a accelerated and affordable model.


Terra is akin successful show to GPT–5.5 but it is 2x cheaper, and Luna offers "strong capability" astatine OpenAI's lowest price. GPT–5.6 Sol is OpenAI's strongest exemplary to date, with agentic improvements successful coding, biology, and cybersecurity. There is simply a caller "max" reasoning effort and an "ultra" mode that uses sub-agents for analyzable work.

OpenAI says GPT–5.6 Sol has its astir "robust information stack to date" with protections for high-risk activity, delicate cyber requests, and misuse.

We are taking this short-term measurement due to the fact that we judge it is the strongest way to broader availability successful the coming weeks, portion we enactment with the Administration to make the cyber Executive Order model and a repeatable process for aboriginal exemplary releases.
The Trump medication is putting unneurotic a process for benchmarking and assessing caller AI models anterior to launch, per a June 2 enforcement order. The medication antecedently forced Anthropic to region entree to Claude Fable 5 and Mythos 5, adjacent though Anthropic adhered to a voluntary authorities reappraisal process and added guardrails based connected authorities feedback.
