OpenAI Launches o1-Pro, Its Most Advanced and Expensive AI Model

The o1-pro API, designed for developers, offers enhanced reasoning capabilities but comes with steep pricing and mixed early feedback.

The o1-pro model, OpenAI's latest offering, is available via API to select developers who meet a $5 minimum spending threshold.
Priced at $150 per million input tokens and $600 per million output tokens, it is OpenAI's most expensive model to date, reflecting its high computational demands.
Key features include a 200,000-token context window, support for vision, function calling, and structured outputs, but no audio input capabilities.
Early user feedback highlights strong programming performance but notes limitations in real-world applications and cost-effectiveness concerns.
The API release follows requests from developers for access to the model, which was previously included in ChatGPT Pro subscriptions since December 2024.
