OpenAI launches GPT-5.5, calling it “a new class of intelligence”

OpenAI launched GPT-5.5 and GPT-5.5 Pro for paying users.

The company says the models improve reasoning, coding, and computer-use tasks while using fewer tokens.

OpenAI says GPT-5.5 matches or beats rivals on several benchmarks, including coding and agentic-computing tests.

The release strengthens OpenAI’s position in frontier AI and could expand use in workflow automation.
