OpenAI just released GPT-5.1, and they say it's a solid upgrade to both Instant and Thinking modes inside ChatGPT.
Here’s what’s new 👇
🧠 Smarter, more conversational answers
- GPT-5.1 Instant now uses light adaptive reasoning — handling tougher questions while still staying quick.
- GPT-5.1 Thinking adapts its thinking time better for complex tasks and gives clearer, less “techy” responses.
- Auto mode continues to route queries to whichever version performs best for your request.
🎨 Better tone and personalization controls
- New tone presets: Default, Friendly, Efficient, Professional, Candid, and Quirky (plus Cynical and Nerdy still available).
- You can now fine-tune how concise, warm, or emoji-filled responses are.
- Updates to your Personalization settings now apply instantly across all chats — even existing ones.
📢 GPT-5.1 is rolling out first to Pro, Plus, Go, and Business users, with Free users to follow soon. I have it in my Business account today.
