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. OpenAI has updated GPT-5.5 Instant, the model you interact with the most when you use ChatGPT, to be better at understanding context and adapting to queries as you alter them to add more conditions or clarifications. The company updated ChatGPT'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.
