OpenAI is preparing to roll out its next-generation AI models, including GPT-5.1, GPT-5.1 Reasoning, and GPT-5.1 Pro, with the Pro version expected at $200 per month for premium users. Early deployment on Microsoft Azure suggests a public release in the coming weeks, following OpenAI’s usual three- to four-month update cycle since GPT-5 launched on August 7, 2025.
The GPT-5.1 lineup promises improved speed, smoother interactions, and stronger safeguards for sensitive or health-related queries. While the updates may not be revolutionary, they aim to make AI tools more reliable, safe, and efficient.
| Model | Key Feature |
| GPT-5.1 | Base model, faster and safer |
| GPT-5.1 Reasoning | Enhanced reasoning capabilities |
| GPT-5.1 Pro | Premium access, priority processing, $200/month |
OpenAI is also enhancing its Codex models for code generation. The recently released GPT-5-Codex-Mini offers 50% higher rate limits, making it ideal for lighter coding tasks and minimizing workflow interruptions for developers.
According to OpenAI,
“Codex-Mini ensures developers can continue working smoothly even when nearing usage limits.”
The upcoming GPT-5.1 update will further improve code generation speed and accuracy, benefiting ChatGPT Plus, Business, Education, Pro, and Enterprise subscribers. Meanwhile, competitors like Google Gemini 3 Pro and Anthropic Claude indicate a rapidly evolving AI race.
In short, GPT-5.1 is set to enhance user experience with better performance, advanced features, and improved reliability, marking another step in OpenAI’s AI evolution.
