Less than 24 hours after news broke that OpenAI would stagger its next model release at the request of the Trump administration, that model, GPT-5.6, is here. On Friday, the company unveiled the limited preview of its new GPT 5.6 model suite: Sol, the flagship; Terra, a medium-tier model for “high-volume work”; and Luna, a “fast and affordable” everyday model. OpenAI says it’s especially skilled at coding, cybersecurity, and biology, as well as staying focused during long-horizon agentic AI tasks.
Per million tokens, GPT-5.6 Sol is priced at $5 input / $30 output (nearly half the cost of Anthropic’s Claude Fable 5, which is $10 input / $50 output). Terra is half the cost of Sol, and Luna is less than half the cost of Terra. The company also debuted two additional modes for Sol: a “max” mode for deeper reasoning and an “ultra” mode for leveraging sub-agents — evoking OpenClaw, and perhaps a sign of OpenClaw creator Peter Steinberger’s work at OpenAI so far.
Unsurprisingly amid a security panic in Washington, D.C., OpenAI dedicated the majority of its announcement blog post to safety and potential misuse. It appeared to reference the recent jailbreaking travails of its rival Anthropic, writing that “GPT‐5.6 is trained to refuse prohibited cyber assistance, including when users attempt to disguise their intent or jailbreak the model.” It also said that flagship model Sol “is better at helping people find and fix vulnerabilities than reliably carrying out end-to-end attacks,” and that Sol doesn’t cross the cyber-critical threshold under OpenAI’s preparedness framework — though it should be noted that OpenAI recently revised its preparedness framework in April and removed some areas of previous study.
