The OpenAI o1 model is an improved version of the o1-preview model, with several key differences and enhancements:
Image Analysis: The full o1 model introduces the ability to analyze and respond to uploaded images, a feature not present in o1-preview[4][7].
Enhanced Reasoning: The o1 model demonstrates a 34% reduction in major errors on difficult problems compared to o1-preview[7].
Expanded Context Window: O1 boasts a larger context window of 200K tokens and a maximum output of 100K tokens, providing more capacity for complex and detailed responses[4].
Developer Messages: O1 supports developer messages, similar to system messages in GPT models, allowing for instructions and context to be passed for specific use cases[4].
Reasoning Effort Parameter: The o1 model introduces a "reasoning_effort" parameter, enabling users to adjust the model's cognitive load with options for low, medium, and high reasoning levels[4][9].
Structured Outputs: O1 adds support for structured outputs, simplifying the generation of well-defined outputs constrained with JSON schemas[4].
Function Calling: The full o1 model in the API supports function calling, allowing it to be connected to external data sources[9].
Improved Accuracy: The graduated o1 model shows significant improvements in accuracy and performance across various benchmarks compared to o1-preview[7][8].
Customizability: O1 in the OpenAI API offers more customization options than o1-preview, thanks to the new features mentioned above[9].
API Access: The full o1 model is being made available through the OpenAI API to certain developers, whereas o1-preview was more limited in its release[9].
ChatGPT Integration: OpenAI plans to integrate the new o1 model into their ChatGPT platform, expanding its availability beyond the API[9].
These enhancements make the full o1 model a more powerful and versatile tool for complex reasoning tasks, image analysis, and customizable AI applications compared to its preview version.
