US Commerce Dept clears OpenAI to broadly release GPT-5.6; Sol launches tomorrow

美国商务部批准OpenAI大规模发布GPT-5.6，Sol明日亮相

The US Commerce Department approved OpenAI's broad release of GPT-5.6, ending a phased rollout that had been required on national security grounds. OpenAI says the Sol model will launch publicly this Thursday alongside Terra and Luna. Last month the model was only available to a limited set of government-approved entities; OpenAI stated at the time that a phased release was not its preferred approach. Testing was handled by the Commerce Department's AI Standards and Innovation Center, with OpenAI engineers stationed in Washington to respond to questions. The post does not disclose GPT-5.6's capabilities, pricing, benchmarks, or how Sol, Terra, and Luna differ from one another.

Why it matters: Full approval for GPT-5.6 is one of the week's biggest industry signals, directly shaping product and developer ecosystems in the coming weeks. Sol's launch tomorrow adds urgency. The post doesn't detail GPT-5.6's capability changes, so it stays below 95.
