Enables configuration of custom base URLs for OpenAI-compatible APIs through environment variables. This supports: - Azure OpenAI endpoints - Custom proxy servers - Local LLM deployments (Ollama, LocalAI, vLLM, etc.) - Any OpenAI-compatible API Environment variables: - OPENAI_API_BASE: Custom endpoint URL (e.g., http://localhost:11434/v1 for Ollama) - OPENAI_API_TYPE: API type (set to 'azure' for Azure OpenAI) - OPENAI_API_VERSION: API version (required for Azure, e.g., '2024-02-01') - OPENAI_API_KEY: API key (optional for local endpoints like Ollama) When OPENAI_API_BASE is set, the runtime uses the custom endpoint instead of the default OpenAI API. Azure-specific headers are automatically applied when OPENAI_API_TYPE=azure. Local endpoints that don't require authentication (like Ollama) work without an API key. Examples: - Ollama: OPENAI_API_BASE=http://localhost:11434/v1 (no key needed) - Azure: OPENAI_API_BASE=https://your-resource.openai.azure.com OPENAI_API_TYPE=azure OPENAI_API_VERSION=2024-02-01 OPENAI_API_KEY=your-key
