- Prices — live list prices from OpenRouter, blended 3:1 input:output. Monthly figures price a RAG assistant with the published cached-input rate where there is one.
- Same job — suggestions must support every capability GPT-5.4 Mini has among tool calling and image input. Other listings of the same model (free or batch tiers) are variants, not alternatives, and are left out.
