Overview
DeepSeek-V4 Flash is the lightweight sibling of V4 Pro (284B-parameter MoE, 13B active, MIT), built for high-volume, latency-sensitive work. It keeps the V4 generation's 1M-token context, native image input, and DeepSeek Sparse Attention while cutting price to roughly a third of Pro's and running noticeably faster. It is one of the cheapest capable multimodal long-context models available, ideal as a router target for the bulk of everyday traffic, stepping up to Pro or a frontier model only for the hardest jobs.
Strengths
- Extremely cheap — among the lowest prices anywhere
- Fast, low-latency decoding for high-volume work
- 1M-token context and native image input
- MIT open weights, self-hostable
Trade-offs
- Well below the frontier on hard reasoning and coding
- Not for long-horizon autonomous agentic work
- Vision quality is basic
- Smaller active-parameter budget caps peak quality
Fit
Best for
- High-volume classification, extraction, and routing
- Cheap long-context document processing
- Low-latency chat and simple coding
- Batch multimodal (image + text) workloads
Not ideal for
- Complex autonomous coding
- Deep multi-step frontier reasoning
