Which Model Should You Pick?
Pick DeepSeek V4 Flash when…
- You need agent/tool-use performance at the lowest cost
- Your workload needs the 1M-token context window
- You want to self-host at 400 tps on affordable hardware
- MIT license and open weights matter to your deployment
Pick the others when…
- V4 Pro — maximum quality, willing to pay 3x more per token
- Qwen3.7 Flash — slightly cheaper, acceptable for non-agent tasks
- GPT-5.5 Mini — enterprise compliance requires a closed-source vendor
Comparison FAQ
Should I use V4 Flash or V4 Pro?
V4 Flash for agent workloads, high-volume tasks, and cost-sensitive deployments. V4 Pro for maximum quality on complex reasoning tasks — though note that V4 Pro is still in Preview and V4 Flash's official release already exceeds its agent scores.
How does V4 Flash compare to Qwen3.7 Flash?
Qwen3.7 Flash is slightly cheaper ($0.10 vs $0.14/M input) but has a 256K context vs V4 Flash's 1M, and lacks comparable agentic benchmark results. V4 Flash is the better choice for agent workloads and long-context tasks.
Can V4 Flash replace Claude for coding agents?
For many coding agent use cases, yes — at 1/20th the per-token cost. Claude Sonnet still leads on nuanced instruction following and safety, but Its agent benchmark scores are competitive and the cost difference is massive.
Is V4 Flash multimodal?
No. V4 Flash is text-only. For vision tasks, DeepSeek offers separate VL (Vision-Language) models. This is a text-focused agent and coding model.
