GPT-5.5 Instant: smarter, clearer, and more personalized
OpenAI has released GPT-5.5 Instant, which is now the default model for the free version of ChatGPT. The company claims the new model offers significant improvements in speed, clarity, and the ability to follow complex instructions with fewer hallucinations. This update aims to provide a more reliable and personalized experience for all users.
MY TAKE
A new default model from OpenAI is always a big deal, and the claimed reduction in hallucinations is what every developer wants to hear. We'll need to see how it performs in production, but this could make building reliable AI-powered features much easier.
