AI-summarised brief · reviewed before publication
OpenAI has launched ChatGPT-5.5 Instant, a new model designed to provide shorter, faster answers without the excessive explanation that previous versions were known for. The model uses roughly 30% fewer words in certain scenarios and demonstrates improved intent understanding, allowing it to deliver more focused responses. GPT-5.5 Instant also shows a significant reduction in hallucinations, especially in high-stakes areas, and can correct its own mistakes in real-time.
