@openai: GPT-5.5 Instant, which is available to all users for free in ChatGPT, is now on par with our frontier Thinking models for health-related questions. Every week, more than 230 million people turn to ChatGPT with health and wellness questions, and GPT-5.5 Instant is better at recognizing when urgent care may be needed, asking for relevant context, explaining uncertainty, and making complex information easier to understand. To improve our models, we collaborate with a global network of hundreds of physicians across 60 countries, 49 languages, and 26 specialties. Their feedback helps us identify where responses miss important context, sound overly confident, need clearer next steps, or should more strongly encourage someone to seek medical care. We believe improving human health will be one of the most personal, tangible impacts of AGI. Our goal is to make ChatGPT not only more accurate, more useful, and more impactful in those moments, but to keep bringing that progress to more people.
