OpenAI released GPT-5.5, its newest AI model, to its paid subscribers on Thursday. The release, coming just six weeks after the company debuted GPT-5.4, is an extremely fast turnaround that underscores how fiercely frontier AI labs are competing for enterprise customers. OpenAI president Greg Brockman called the new model a "new class of intelligence" and noted GPT-5.5 can do more with less guidance and is "way more intuitive to use."

OpenAI released GPT-5.5, its latest artificial intelligence model, advancing its push into systems that can handle real-world work with less human input. GPT-5.5 is not just more capable but also more efficient at solving problems, often producing higher-quality results with fewer tokens and fewer retries. OpenAI said GPT-5.5 does not exceed its "Critical" cybersecurity risk threshold but meets the bar for a "High" risk classification.
