GPT-5.1: Two New Models

OpenAI released GPT-5.1, the next generation of the AI model powering ChatGPT, on november 12, 2025. The​ update includes two versions: ‌GPT-5.1 Prompt and GPT-5.1 Considering.

Key Differences Between Prompt and Considering

According⁣ to OpenAI, GPT-5.1 ​prompt ⁣is designed to be warmer, more intelligent, and ‍better‍ at following ⁤user instructions. GPT-5.1⁤ Considering is ​easier to ⁣understand, faster for simple ⁢tasks,‍ and more ⁤persistent when handling⁣ complex requests.

Both models aim to provide a more pleasant communication experience, with expanded options for customizing ChatGPT’s tone.

New and Updated Tone Presets

ChatGPT now offers ⁣new tone⁢ presets including Skilled,‌ Candid, and Quirky, joining ⁢existing options like Standard, Nerdy, ‌Cynical, Pleasant (previously Listener),​ and Efficient (previously Robot). The AI will proactively suggest preference updates​ during ‍conversations based on requested tones or ⁣styles.

Users ‍can ‌also fine-tune responses for conciseness, warmth, readability, and emoji frequency.

Enhanced Model Capabilities

By default, GPT-5.1 Prompt is more engaging and‍ likely to⁢ adhere to ⁣specified parameters. GPT-5.1 Considering adapts its ‍processing time to the ‍complexity of the question, delivering clearer answers with fewer ambiguous terms. It also exhibits increased warmth and empathy.

Rollout⁢ and ⁢Access

openai will route questions⁤ to the most appropriate model⁣ using GPT-5.1 Auto. GPT-5.1 ⁣Prompt​ and Considering are​ rolling out to users starting November 12, 2025, with priority access given to paid Professional, Plus, Go, and Enterprise subscribers. Free and disconnected⁢ users‌ will receive access after them.

Enterprise⁢ and ⁣Education users will have a seven-day early⁤ access‍ period before GPT-5.1 ​becomes the default model. OpenAI plans a gradual rollout to maintain performance ⁢stability.

GPT-5 will remain available in the legacy model dropdown⁤ for paid subscribers for the next three months.
