How alternatives are chosen

- 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 DeepSeek V4 Flash 0423 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.
