# DeepSeek

DeepSeek's reasoning-first LLMs — flash for fast, low-cost work and pro for complex agentic tasks, via one RunAPI key.

DeepSeek builds reasoning-first large language models. The v4 line spans deepseek-v4-flash (fast, low-cost, optional thinking) and deepseek-v4-pro (frontier reasoning and agentic work). Both are available through RunAPI from the OpenAI and Anthropic SDKs.

## FAQ

### Is this an official %{provider} integration?

RunAPI exposes a managed API surface with transparent pricing, capability, and error behavior.

### Do I need a %{provider} account?

No — your RunAPI key is enough for managed access.

### What's the latency overhead from proxying?

Typically under 20 ms. RunAPI keeps the proxy layer close to model execution regions.

### Are images / videos cached?

Generated outputs are stored and retrievable by task ID. Inputs are not cached.

### Can I bring my own key?

Not currently — calls use RunAPI-managed access.
