What is DeepSeek V4 Flash?

DeepSeek V4 Flash is a DeepSeek V4 model from DeepSeek for chat, reasoning, coding and agent workflows. On Crazyrouter it runs behind the same API key and billing account as 300+ other models, so you can benchmark it against alternatives and route traffic without new credentials.

Drop-in OpenAI compatibility

Works with the OpenAI SDKs, LangChain, Cursor, Cline and any tool that accepts a custom base URL.

Streaming and tool use

Streaming, tools and structured output depend on the model and upstream channel. Check the required feature on your channel before production use.

Live, discounted pricing

Rates on this page come straight from the billing table and already include the Crazyrouter discount.

One account for every model

Compare against Claude, GPT, Gemini, DeepSeek and more without juggling vendor accounts.
