THEN Replace the base URL in provider SDK configurations to point to the local Bifrost endpoint. For example, change OpenAI's base_url from 'https://api.openai.com' to 'http://site_1:8080/openai', or Anthropic's from 'https://api.anthropic.com' to 'http://site_2:8080/anthropic'. This works with any OpenAI-compatible SDK.

```diff
# OpenAI SDK
- base_url = "https://api.openai.com"
+ base_url = "http://localhost:8080/openai"

# Anthropic SDK  
- base_url = "https://api.anthropic.com"
+ base_url = "http://localhost:8080/anthropic"

# Google GenAI SDK
- api_endpoint = "https://generativelanguage.googleapis.com"
+ api_endpoint = "http://localhost:8080/genai"
```
