Our editorial assessment, based on the public sources listed below. Last reviewed .
- Overall rank
- #67
- Tier
- A
- Score
- 71.5
- Main category
- Coding
Strengths
- Captures most of the larger V4 Pro's agentic capability at a fraction of the cost
- MIT-licensed sparse MoE with a one-million-token context
- Teams have dropped it straight into real agentic pipelines
Considerations
- Still measurably behind the larger V4 Pro variant on coding evaluations
- Advertised cache-hit pricing only applies when prefixes actually reuse
- Chinese-hosted routes need a data residency review for some buyers
Price
Open weights (MIT); the deepseek-v4-flash API name now routes to V4.1-Flash at $0.30 input / $1.20 output per 1M tokens peak ($0.15 / $0.60 off-peak)
