OpenAI Unveils o1-pro: A Heavy-Duty Reasoning Model for Professionals

What Capabilities Does $600 per One Million Tokens Unlock?

The price point makes OpenAI o1-pro one of the priciest AI models, taking the crown from API access to the Silicon Valley darling’s own GPT-4.5. (GPT-4.5 costs $75 per million input tokens and $150 per million output tokens.)

What do you get for that cash? OpenAI is probably hoping for o1-pro to bring in a deep-pocketed handful of researchers, engineers, and other professionals using generative AI for science, medicine, or technology. While o1-pro is optimized for reasoning tasks, OpenAI offers separate models for transcription or moderation. A smaller, cheaper model can probably meet users’ needs for those.

For the price of o1-pro, you get a 200,000 context window and 100,000 max output tokens.

Capabilities of o1-pro

OpenAI o1-pro can interpret data from machine vision, with text and image input. However, it only produces text output. In the API, it supports:

• Function calling.
• Structured Outputs, which ensure the model’s response will conform to the developer’s JSON Schema.
• Integration with the Responses API, which can be used to create AI agents that can interact with the web in various ways, including running searches.
• Integration with the Batch API, which allows for asynchronous requests, providing lower costs and higher rate limits for jobs with a 24-hour turnaround time.

What is o1-pro?

OpenAI introduced o1 as “Strawberry” in September 2024. It competes with DeepSeek’s R1, Anthropic’s Claude Sonnet 3.7, Grok 3, Google’s Gemini 2.0, and other reasoning models. Meta is working on “theory of mind reasoning,” but that’s a slightly different matter: Meta says it is an adversarial project for evaluating advanced AI models.

Conclusion

In conclusion, OpenAI o1-pro is a heavy-duty reasoning model designed for professionals who require advanced AI capabilities. With its high-capacity context window and output tokens, o1-pro is ideal for those who need to process and generate complex information. However, its high price point may limit its adoption to only a select few.
