How o1 mini is used in this material o1 mini appears in this material as the workhorse coding model within OpenAI's o1 family — the smaller, faster sibling of o1 preview. Two videos show it in action and explain the choice[^20a397df-10fb-596f-826a-f54787502261@122][^4ef67c54-9505-5bc4-a565-9579a83f2827@41]. Why pick o1 mini? The videos lay out a clear trade-off between the two o1 variants: In practice: the Hermes build In the Hermes demo — an SMS reading companion — the architecture assigns each model to its specialty: GPT-4 handles image-to-text, o1 preview interprets the transcription, and o1 mini writes the code[^4ef67c54-9505-5bc4-a565-9579a83f2827@234]. The builder even feeds the models their own documentation when they don't know about newer capabilities[^4ef67c54-9505-5bc4-a565-9579a83f2827@302]. Choosing between the two models When deciding which o1 model to use, the guidance from the material is: - o1 mini is the smaller, faster o1 model — a bit better at programming, but it knows less about the world.- Reach for it on math and coding problems; reach for o1 preview when questions need broad world knowledge.- In the Hermes build, o1 mini is deliberately assigned the coding step of the pipeline[^4ef67c54-9505-5bc4-a565-9579a83f2827@234].- Its speed makes it practical even when you can do dumb stuff and still get this thing working really quick[^4ef67c54-9505-5bc4-a565-9579a83f2827@585].
