OpenAI has officially launched the o3-mini AI inference model for ChatGPT and API services, making it available for the first time to free ChatGPT users at a limited rate.
In terms of performance, o3-mini offers a 24% improvement in response speed compared to o1-mini, along with enhanced accuracy. Similar to o1-mini, o3-mini presents its reasoning process rather than just providing answers. Developers can access o3-mini through OpenAI's API services, including the Chat Completions API, Assistants API, and Batch API.
For the first time, free ChatGPT users can experience OpenAI's inference model by selecting the “Reason” feature in the chat interface, with rate limits similar to those of GPT-4o. Paid subscribers also have access to o3-mini-high, a more advanced version with higher intelligence but slightly longer response times. Only Pro users, who pay $200 per month, enjoy unlimited access to both o3-mini and o3-mini-high.
