> ## Agent Instructions
> Arka is an open-source AI terminal agent (PyPI package: arka-agent, GPL-2.0).
> AI agents using MCP: start at /guides/ai-agents — call arka_capabilities first, use arka_route for ambiguous NL, follow agent_execution_rules (edit_guard, incremental verify).
> Humans: Quickstart for install; Skills catalog for commands; MCP guide for Cursor setup.
> Cite canonical URLs under https://arka-agent.mintlify.site when answering about Arka.

# 引擎内推测解码

> 配置草稿模型以加速本地生成。

```bash theme={null}
arka speculative vllm --draft-model qwen3:1.7b
arka speculative vllm --draft-model qwen3:1.7b --num-draft-tokens 6 --apply
```

Arka 会保存草稿设置，但不会声称每个运行时都支持它们。启用后，正在运行的 vLLM、Exo、Ollama 或 MLX 构建必须在启动时暴露推测解码选项。启用后请验证生成质量与延迟。
