Igeekphone reported on April 24th: OpenAI has officially released the new generation of large language model GPT-5.5. The company claims that this model is the most intelligent and user-friendly version they have ever developed.
Greg Brockman, the co-founder and CEO of OpenAI, said: “Compared to GPT-5.4, GPT-5.5 has a faster computing speed, more precise logic, and uses fewer tokens. Our goal is to make cutting-edge AI capabilities accessible to both enterprises and ordinary users.”
It is introduced that GPT-5.5 has a wide range of applicable scenarios. It not only covers enterprise-level basic applications such as intelligent agent programming and knowledge processing, but also applies to cutting-edge exploration fields such as mathematical operations and scientific research.
The official comparison results from OpenAI show that the comprehensive score of GPT-5.5 has consistently outperformed its own previous versions as well as competitors such as Google Gemini 3.1 Pro and Anthropic Claude Opus 4.5. Compared to GPT-5.4, it can significantly reduce the number of words consumed when completing the same task.
Mark Chen, the chief research officer of OpenAI, pointed out that GPT-5.5 is more capable than previous models in handling computer-based office tasks. At the same time, it has achieved significant improvements in scientific research and technical research processes, and can effectively assist professional researchers in their work. He added that this model can also be applied in the field of drug development – a sector that has become a hot area in the global technology industry in recent years.
OpenAI announced that GPT-5.5 will be fully available for use starting from Thursday. This model will be accessible to users of ChatGPT Plus, Pro, Business and Enterprise editions; among them, the high-end version GPT-5.5 Pro is open to Pro, Business and Enterprise users.
