Staggered release of ChatGPT 5.6 follows similar restrictions on rival firm Anthropic’s latest AI models
OpenAI released its latest advanced AI model, called ChatGPT 5.6, on Thursday after earlier delaying the public rollout over US government concerns about cybersecurity. The Trump administration had requested last month that OpenAI limit the release to a small group of government-approved users.
OpenAI complied with the White House’s request last month. The company stated in a blogpost that it had briefed government officials on ChatGPT 5.6’s capabilities and restricted the model to trusted partners at their behest. The product’s wider release came after additional testing by the government’s Center for AI Standards and Innovation agency, according to Axios.

Mark Zuckerberg broke a three-year silence on X (Twitter) on Thursday to unveil Muse Spark 1.1 and the Meta Model API, the company’s first paid platform for outside developers. The launch pushes Meta against OpenAI, Anthropic, and Google. The model competes on cost, and Meta is betting a lower price will win developers and pressure rivals’ margins. Yet META stock barely moved, rising only 2% after the news. META Stock Performance. Source: TradingView What Muse Spark 1.1 Can Do Muse Spark 1.1 is what the industry calls an agentic model. It is built to act, not just answer questions. It can plan a task, use software and tools, and operate a computer across desktop, mobile, and browser. We’re excited to introduce Muse Spark 1.1, a significant upgrade from the first Muse Spark model we released earlier this year. Along with this release, we are launching a public preview of th

OpenAI has launched GPT-5.6 across ChatGPT, Codex, and its API, introducing GPT-5.6 Sol with a four-agent reasoning system and two lower-cost models as the rollout begins worldwide. Summary OpenAI has launched the GPT-5.6 family, introducing Sol, Terra, and Luna across ChatGPT, Codex, and its API. GPT-5.6 Sol adds a four-agent reasoning system, new coding tools, and higher-compute modes for complex tasks. Elon Musk confirmed SpaceXAI will release Grok 4.5 on Thursday, intensifying competition in advanced AI models. According to OpenAI, the GPT-5.6 family introduces a new three-tier lineup consisting of Sol, Terra, and Luna, replacing its previous naming approach with capability-based tiers that separate model generation from intelligence, speed, and pricing. The company said availability is expanding across consumer, enterprise, and developer products, with global deployment expec

OpenAI moved GPT-5.6 to general availability on July 9, 2026, shipping three tiers instead of one model. Sol is $5/$30 per 1M tokens, Terra is $2.50/$15, and Luna is $1/$6. Sol sets the Artificial Analysis Coding Agent Index at 80, 2.8 points above Claude Fable 5, and reaches 62.6% on OSWorld 2.0 using 85% fewer output tokens than Opus 4.8. The substantive developer change is Programmatic Tool Calling, which runs model-written JavaScript in an isolated V8 runtime to orchestrate tools without returning every intermediate result to the model. Clio reports a 38% cut in prompt tokens, PlayCo 63.5% fewer total tokens. The gaps are real too: Fable 5 still leads the Artificial Analysis Intelligence Index, GDPval-AA v2, and Toolathlon, and Claude Mythos 5 leads SWE-Bench Pro by roughly 15 points.
