OpenAI is releasing GPT-5.1 today, an update to the flagship model it released in August. OpenAI calls it an "upgrade" to GPT-5 that "makes ChatGPT smarter and more enjoyable to talk to." The new models include GPT-5.1 Instant and GPT-5.1 Thinking. The former is "warmer, more intelligent, and better at following your instructions" than its predecessor, per an OpenAI release, and the latter is "now easier to understand and faster on simple tasks, and more persistent on complex ones."

Robby Stein from Google wrote on X, "We're seeing big improvements for complex STEM questions." He said he was "Very excited about this week's AI Mode model update." It is great for back to school, he added. The changes are that the responses should be "tighter, easier to scan and get to the point up front before elaborating," he explained.
