# DeepSeek

> Use DeepSeek Chat, DeepSeek Coder, and DeepSeek R1 (reasoning) via the DeepSeek API. Highly competitive pricing.

DeepSeek offers some of the best price-to-performance ratios available. DeepSeek R1 is a state-of-the-art reasoning model competitive with o1. DeepSeek Coder excels at programming tasks.

## Supported Models

| Model          | ID                  | Context | Tools | Notes                      |
| -------------- | ------------------- | ------- | ----- | -------------------------- |
| DeepSeek Chat  | `deepseek-chat`     | 64K     | Yes   | General purpose            |
| DeepSeek Coder | `deepseek-coder`    | 128K    | Yes   | Code-optimized             |
| DeepSeek R1    | `deepseek-reasoner` | 64K     | No    | Chain-of-thought reasoning |

## Model Aliases

| Alias            | Model                       |
| ---------------- | --------------------------- |
| `deepseek`       | deepseek-chat               |
| `deepseek-coder` | deepseek-coder              |
| `deepseek-r1`    | deepseek-reasoner           |
| `deepseek-local` | deepseek-r1:7b (via Ollama) |

## Usage Examples

<CodeGroup>
  ```bash CLI theme={null}
  # General chat
  profclaw chat --model deepseek "Explain microservices"

  # Code generation
  profclaw chat --model deepseek-coder "Write a Redis client in TypeScript"

  # Reasoning
  profclaw chat --model deepseek-r1 "Prove that sqrt(2) is irrational"

  # Local (via Ollama)
  profclaw chat --model deepseek-local "Quick local query"
  ```

  ```typescript SDK theme={null}
  import { chat } from 'profclaw';

  const code = await chat("Implement a LRU cache in Go", {
    model: "deepseek-coder",
    temperature: 0.1,
  });
  ```
</CodeGroup>

## Notes

* API endpoint: `https://api.deepseek.com/v1` (OpenAI-compatible)
* Status: Beta
* DeepSeek R1 uses extended chain-of-thought reasoning similar to OpenAI o1.
* `deepseek-reasoner` (R1) does not support tool calling.
* For local/offline use, run `ollama pull deepseek-r1:7b` and use the `deepseek-local` alias.
