OpenAI Releases o1, Its First Model With ‘Reasoning’ Abilities

OpenAI has launched a new AI model, named “o1”, designed for improved reasoning and problem-solving skills. o1, part of a new series of models and available in ChatGPT and the API, can tackle complex tasks in science, coding, and math more effectively than their predecessors. Notably, o1 models have shown promising results in standardized tests and coding competitions. While o1 models represent a significant advancement in AI capabilities, they currently lack features like web browsing and file uploading. The Verge adds: But it’s also more expensive and slower to use than GPT-4o. OpenAI is calling this release of o1 a “preview” to emphasize how nascent it is.

ChatGPT Plus and Team users get access to both o1-preview and o1-mini starting today, while Enterprise and Edu users will get access early next week. OpenAI says it plans to bring o1-mini access to all the free users of ChatGPT but hasn’t set a release date yet. Developer access to o1 is really expensive: In the API, o1-preview is $15 per 1 million input tokens, or chunks of text parsed by the model, and $60 per 1 million output tokens. For comparison, GPT-4o costs $5 per 1 million input tokens and $15 per 1 million output tokens.

The training behind o1 is fundamentally different from its predecessors, OpenAI’s research lead, Jerry Tworek, tells me, though the company is being vague about the exact details. He says o1 “has been trained using a completely new optimization algorithm and a new training dataset specifically tailored for it.”
