OpenAI Refines GPT-5.5 Instant for ChatGPT

OpenAI has updated its default model, GPT-5.5 Instant, to better handle complex, multi-part instructions and maintain context across longer conversations. The model is now designed to adapt more effectively when users provide feedback or additional constraints, rather than repeating previous responses.

Beyond conversational flow, the update improves location-based awareness for recommendations and allows the chatbot to surface images when relevant. These changes aim to make responses feel more cohesive and less templated.
