OpenAI has announced its new GPT-5.5 model, touted as the 'smartest and most intuitive to use' yet, excelling at tasks like writing and debugging code, research, and more.
The latest release follows GPT-5.4 last month and promises improved planning, tool usage, and ambiguity navigation for users.
OpenAI highlights its strongest set of safeguards to date and reduced token usage in Codex, with the new model rolling out to Plus, Pro, Business, and Enterprise ChatGPT tiers and Codex starting Thursday.
The move comes amid a heated battle between OpenAI and Anthropic as they race to potentially go public later this year.
OpenAI's GPT-5.5 release precedes the high-profile trial between Elon Musk and OpenAI executives Sam Altman and Greg Brockman, set to begin on Monday in a federal courtroom in Oakland, California.
