|

📚 如何使用 LiteLLM：
|
||||
|
||||
1. 在 config.toml 中配置：
|
||||
```toml
|
||||
[app]
|
||||
# 方式 1：直接使用 LiteLLM（推荐）
|
||||
vision_llm_provider = "litellm"
|
||||
vision_litellm_model_name = "gemini/gemini-2.0-flash-lite"
|
||||
vision_litellm_api_key = "your-api-key"
|
||||
|
||||
text_llm_provider = "litellm"
|
||||
text_litellm_model_name = "deepseek/deepseek-chat"
|
||||
text_litellm_api_key = "your-api-key"
|
||||
```
|
||||
|
||||
2. 支持的模型格式：
|
||||
- Gemini: gemini/gemini-2.0-flash
|
||||
- DeepSeek: deepseek/deepseek-chat
|
||||
- Qwen: qwen/qwen-plus
|
||||
- OpenAI: gpt-4o, gpt-4o-mini
|
||||
- SiliconFlow: siliconflow/deepseek-ai/DeepSeek-R1
|
||||
- 更多: 参考 https://docs.litellm.ai/docs/providers
|
||||
|
||||
3. 代码调用示例：
|
||||
```python
|
||||
from app.services.llm.unified_service import UnifiedLLMService
|
||||
|
||||
# 文本生成
|
||||
result = await UnifiedLLMService.generate_text(
|
||||
prompt="你好",
|
||||
provider="litellm"
|
||||
)
|
||||
|
||||
# 视觉分析
|
||||
results = await UnifiedLLMService.analyze_images(
|
||||
images=["path/to/image.jpg"],
|
||||
prompt="描述这张图片",
|
||||
provider="litellm"
|
||||
)
|
||||
```
|
||||
|
||||
4. 优势：
|
||||
✅ 减少 80% 代码量
|
||||
✅ 统一的错误处理
|
||||
✅ 自动重试机制
|
||||
✅ 支持 100+ providers
|
||||
✅ 自动成本追踪
|
||||
|
||||
5. 迁移建议：
|
||||
- 新项目：直接使用 LiteLLM
|
||||
- 旧项目：逐步迁移，旧的 provider 仍然可用
|
||||
- 测试充分后再切换生产环境
