o1

service active paid

OpenAI's reasoning-focused model family released in late 2024. o1 models use extended "thinking" time to solve complex problems, particularly excelling at math, coding, and scientific reasoning. The architecture prioritizes reasoning depth over response speed, representing a new paradigm in LLM design.

Implements

Concepts this tool claims to implement:

  • Advanced language model with novel reasoning architecture focused on multi-step problem solving.

  • Reasoning primary

    Extended thinking/reasoning chains before producing output. Significantly outperforms GPT-4 on complex reasoning tasks.

  • Built-in chain-of-thought reasoning as a core architectural feature rather than prompting technique.

Integration Surfaces

  • REST API
  • Python SDK
  • Node.js SDK

Notes

o1 represents a shift from "faster tokens" to "better thinking." The model family demonstrates that inference-time compute (thinking longer) can significantly improve reasoning performance, influencing how future models are designed and deployed.
