6 May
Summary
- GPT-5.5 Instant is now the default free model for ChatGPT.
- New model offers natural tone and fewer hallucinations.
- It can better judge web searches and analyze images.
OpenAI has rolled out GPT-5.5 Instant as the new default model for ChatGPT, making it accessible to all users without cost. This update replaces the previous default model, GPT-5.3 Instant, which will be phased out for paid subscribers after three months. The GPT-5.5 Instant model, distinct from the paid GPT-5.5 version released in April, aims to provide a more natural and concise conversational experience.
Improvements in GPT-5.5 Instant include a stronger ability to recall context from past interactions and significantly fewer hallucinations. OpenAI reports a 52.5% reduction in incorrect factual statements on critical subjects like law, finance, and medicine during internal testing. The model also features enhanced capabilities for determining when to conduct web searches and improved image analysis.
Further advancements allow GPT-5.5 Instant to leverage connected accounts, such as Gmail, for more personalized and relevant responses. This move positions the free version of ChatGPT competitively against other AI models that remain behind paywalls, democratizing access to advanced AI technology.
