OpenAI Updates GPT-5.5 Instant For Better Intent
OpenAI updated GPT-5.5 Instant to improve intent recognition and multi-turn context. The update specifically targets complex, multi-condition prompts to reduce hallucinations and errors. This is an incremental refinement of the most-used ChatGPT model. Practitioners should notice more reliable adherence to strict constraints during long conversations without changing their existing prompt structures.
