DeepSeek V4-Flash vs Muse Spark
Values come from DeepSeek V4-Flash and Muse Spark, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Input price
- DeepSeek V4-Flash at $0.14/M against $1.25/M — 8.9× 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 $4.25/M — 15.2× 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), Muse Spark under proprietary (closed / API-only, not open-weights). Check the licences rather than assuming they permit the same commercial use.
- Recency
- DeepSeek V4-Flash shipped 114 days after Muse Spark (2026-07-31 vs 2026-04-08).
