DeepSeek V4 — frontier reasoning at a fraction of Western frontier token prices.
2
シリーズ内のモデル数
DeepSeek V4 comes in two tiers, and the reason to look at them is price. Pro is a frontier reasoning model at an input price below most other vendors' cheap tiers, and Flash sits an order of magnitude below that again. Cache reads are the standout number: on Flash they are priced at roughly a three-hundredth of fresh input, the most aggressive caching discount in the catalog.

どれを選ぶか
DeepSeek V4 Flash
High-volume classification, extraction and chat where per-token cost dominates the decision.
DeepSeek V4 Pro
Maths, coding and long analytical chains — frontier reasoning without frontier pricing.
強み
- The cheapest frontier-class reasoning in the catalog on a per-token basis.
- Cache reads on Flash are priced at a rounding error, which makes long fixed prompts almost free to reuse.
- Output is only three times input on both tiers, a narrower ratio than the GPT or Claude lines.
- OpenAI-protocol compatible, so it drops into existing code.
制限
- Only two tiers, with no mid-range option between them.
- Cache writes are not priced separately here, so caching economics differ from the GPT line.
- Text-only — no image input in this family.
