What actually differs
- Input price
- DeepSeek V4-Flash at $0.14/M against $10/M — 71.4× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- DeepSeek V4-Flash at $0.28/M against $50/M — 178.6× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
