Microsoft-backed (MSFT) OpenAI said Tuesday that it has released ChatGPT-5.3 Instant, aiming to deliver more accurate answers and better-contextualized results and reduce overly declarative phrasing that can interrupt the flow of conversations.

An update over the GPT-5.2 Instant, GPT-5.3 Instant cuts hallucination rates by 26.8% while using the web and 19.7% when relying only on its internal knowledge, compared with previous models, the company said.

OpenAI further said that GPT-5.3 Instant is available starting today to all ChatGPT users.
