OpenAI releases GPT-5.5, a more powerful engine for coding, science, and general work

# OpenAI Releases GPT-5.5, Its Most Powerful AI Yet OpenAI just released GPT-5.5, a new AI system that's better at handling complex work tasks—especially coding, scientific research, and multi-step projects that normally require human oversight. The system can now tackle longer chains of work independently, like running multiple computer commands in sequence or testing new scientific ideas without constant direction. With 4 million developers already using OpenAI's coding tools weekly, this upgrade positions the company ahead of competitors like Google and Anthropic in the race to build AI that can work more autonomously.
