# Embeddings
|
|
|
|
This project uses QWEN embeddings. The model used is `qwen/qwen3-embedding-4b` via OpenRouter-compatible API providers.
|
|
|
|
API key preference
|
|
- Preferred environment variable: `OPENROUTER_API_KEY`
|
|
- Fallback: `OPENAI_API_KEY`
|
|
|
|
When the application needs to compute embeddings it will prefer the OpenRouter API key (OPENROUTER_API_KEY). If that is not set, it will fall back to using `OPENAI_API_KEY` where supported by the client libraries.
|
|
|
|
Example environment variables
|
|
|
|
```
|
|
OPENROUTER_API_KEY=or-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
|
|
# or fallback
|
|
OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
|
|
```
|
|

Notes
|
|
- QWEN embedding models may be provided through OpenRouter or other proxies that expose the same API surface. Ensure your provider supports the `qwen/qwen3-embedding-4b` embedding model.
|
|
- Using OpenRouter is recommended to access QWEN embeddings when you don't have native access through OpenAI-compatible endpoints.
