- ChatGPT's default model has been updated to GPT-5.5 Instant for all users, offering smarter, more accurate, and clearer answers with a more natural tone.
- The new model reduces hallucinated claims by 52.5% and inaccurate claims by 37.3% on high-stakes prompts, improving factuality in domains like medicine, law, and finance.
- It provides stronger performance in visual reasoning, math, science, and STEM-related questions, while delivering tighter, less verbose responses without unnecessary formatting.
- Enhanced personalization uses context from past chats, files, and connected Gmail to tailor answers, with memory sources that allow users to see and control the context used.
- GPT-5.5 Instant is rolling out immediately as the default, with GPT-5.3 Instant available to paid users for three months before retirement, and new features will expand to other plans soon.
