What actually differs
- Input price
- DeepSeek V4-Flash at $0.14/M against $1/M — 7.1× 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 $2/M — 7.1× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — DeepSeek V4-Flash under MIT (open-weight), Grok Build under Apache 2.0 (CLI codebase, open-sourced 2026-07-16). Check the licences rather than assuming they permit the same commercial use.
- Recency
- DeepSeek V4-Flash shipped 78 days after Grok Build (2026-07-31 vs 2026-05-14).
