FAQ
We recommend that developers use GPT‑4o or GPT‑4o mini for everyday tasks. GPT‑4o generally performs better on a wide range of tasks, while GPT‑4o mini is fast and inexpensive for simpler tasks. Our o1 reasoning models are ideal for complex, multi-step tasks and STEM use cases that require deep thinking about tough problems. We recommend experimenting with all of these models in the Playground(opens in a new window) to explore which models provide the best price performance trade-off for your usage.
