09. LLM集成对比：Crush vs Kimi Code CLI

9.1 LLM抽象层

Crush: Fantasy

charm.land/fantasy
- fantasy.Generate()
- fantasy.Stream()
- fantasy.AgentTool

Kimi Code CLI: Kosong

packages/kosong/
- ChatProvider Protocol
- step()
- generate()
- Toolset

9.2 支持的Provider

Crush (10+)

Kimi Code CLI (7+)

9.3 流式处理

Crush: 回调函数

fantasy.Stream(ctx, fantasy.AgentStreamCall{
    OnTextDelta: func(delta string) { ... },
    OnToolCall: func(tc ToolCall) { ... },
    OnReasoningDelta: func(delta string) { ... },
})

Kimi Code CLI: 异步迭代器

async for part in result:
    if part.text:
        wire_send(ContentPart(part=part))
    if part.tool_call:
        result = await toolset.handle(part.tool_call)

9.4 上下文压缩

Crush: 自动摘要

func (a *sessionAgent) Summarize(...) {
    // 使用小模型生成摘要
    // 保留最后N条消息
    // 替换历史为摘要
}

Kimi Code CLI: compact + checkpoint

async def compact_context(self):
    summary = await self._summarize(history)
    self._context._history = [
        Message(content=f"[Summary]\n{summary}"),
        last_msg,
    ]
