Our pick

For most workloads, choose GPT-5 mini.

  • 17% cheaper input price, which compounds at scale

GPT-5 family inheritance at a fraction of the cost — strong on routine tasks but visibly weaker on multi-step reasoning. Default choice when GPT-5 is overkill.

Choose Gemini 2.5 Flash instead if: The price-performance benchmark for vision tasks. Strong multimodal, weak on deep reasoning. Pair as a fast first hop ahead of a smarter fallback.
