OpenAI released GPT-5.1 for ChatGPT on November 12, 2025. OpenAI+1 I think GPT 5 provides better responses, tone, and does what you ask it to do. 5.1 seems a bit wonky...its still getting its baby legs. I'll drop a new Youtube video on this soon. Here's what changed: 1. Two tuned variants⢠GPT-5.1 Instant ā keeps answers fast but adds light adaptive reasoning so it follows instructions better for everyday prompts.⢠GPT-5.1 Thinking ā spends more time on complex tasks, gives clearer, less jargony answers, and is more persistent on multistep problems. OpenAI Help Center+1 2. More conversational voice and personality controls⢠OpenAI added multiple chat styles so you can pick tones like Friendly, Professional, Quirky and more. The model aims to sound warmer and more natural. The Verge+1 3. Smarter automatic model selection and UX changes⢠ChatGPT now automatically matches Instant or Thinking to tasks rather than you swapping models manually. Legacy GPT-5 remains available for a short period. MacRumors+1 4. Quality and guardrail tweaks, plus speed tweaks for simple tasks⢠OpenAI says the update improves instruction following and balances speed versus depth. Analysts report modest, focused improvements rather than a dramatic leap over GPT-5. Venturebeat+1 I am NOT impressed! Have you tried it out? š
