OpenAI's free GPT-5.5 model makes ChatGPT better at understanding context

GPT-5.5 Instant is now more capable at processing complex questions.

Alexsl/Getty Images Open AI has updated GPT-5.5 Instant, the model you interact with the most when you use Chat GPT, to be better at understanding context and adapting to queries as you alter them to add more conditions or clarifications. The company updated Chat GPT's default model to GPT-5.5 Instant in May. Back then, it said that the model produced 52.5 percent fewer hallucinated statements during testing and 37.3 percent fewer factual errors.

Now, the model has been upgraded to be more capable when it comes to identifying the underlying goal of a task or a question and carrying context over across multiple back-and-forths as you talk to it. GPT-5.5 Instant is now also better at processing complex questions and is more likely to answer the multiple points you want it to address. If you clarify your question further or push back on its answer, OpenAI says the model should adapt more effectively and give you more relevant answers instead of repeating its old ones. And since it's the default model for the company's chatbot, you're supposed to feel these quality-of-life upgrades when you use ChatGPT.
