# OpenAI Releases GPT-5.5 Instant OpenAI has released a new version of ChatGPT called GPT-5.5 Instant that's designed to be more reliable when handling important professional topics like legal advice, medical information, and financial guidance. The main improvement is that it makes up fewer false details—a problem that can be especially costly in these sensitive fields—while still responding just as quickly as before.
The company said the model reduces hallucination in sensitive areas such as law, medicine, and finance, while maintaining the low latency of its predecessor.
