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:
- Two tuned variants• GPT-5.1 Instant — keeps answers fast but adds light adaptive reasoning so it follows instructions better for everyday prompts.• GPT-5.1 Thinking — spends more time on complex tasks, gives clearer, less jargony answers, and is more persistent on multistep problems. OpenAI Help Center+1
- 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
- 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
- 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? 👇
