README

DeepSeek-V4-Flash is the lower-cost DeepSeek V4 option for enterprise teams that need responsive text generation, practical reasoning, and efficient token economics.

DeepSeek-V4-Flash is appropriate for high-volume assistants, routing tiers, extraction tasks, and latency-sensitive workflows where cost control is important.
The model's OpenAI-compatible chat interface helps teams adopt it behind existing API gateways, SDKs, and observability pipelines.
Cache-hit pricing can materially reduce repeated context cost for stable prompts, retrieval wrappers, and policy-heavy enterprise applications.
