SAN FRANCISCO, July 9 (Xinhua) -- U.S. artificial intelligence company OpenAI on Thursday announced the general availability of GPT-5.6, its latest family of AI models, after a rollout was delayed last month at the U.S. government's request over cybersecurity concerns.
The GPT-5.6 family includes three models: Sol, the company's new flagship model; Terra, a balanced model for everyday work; and Luna, its fastest and most cost-efficient model, OpenAI said in a statement.
The company said GPT-5.6 Sol sets a new standard for intelligence and efficiency across coding, knowledge work, cybersecurity and science, while using fewer tokens and lowering estimated costs compared with previous and competing frontier models.
OpenAI also introduced two new capability settings for the model family. The "max" setting gives GPT-5.6 more time to reason, check and revise its approach, while the "ultra" setting coordinates multiple agents in parallel to handle more complex tasks.
According to the company, GPT-5.6 became available on Thursday across ChatGPT, Codex and the OpenAI API, with the global rollout expected to continue gradually over the next 24 hours.
OpenAI said GPT-5.6 is launching with its "most robust safeguards to date." The company said the models are more capable than earlier models in biology and cybersecurity, but do not cross the "critical" threshold in either category under its preparedness framework. The company added that the models underwent its most extensive safety evaluations to date before general availability. ■
