What kind of change does this PR introduce?
Feature - Configurable AI/LLM providers via environment variables
Why was this change needed?
Currently, the AI functionality is hardcoded to use OpenAI. This limits users who want to use alternative providers like Anthropic, Google AI, Azure OpenAI, Ollama (self-hosted), or Groq. This change allows users to configure their preferred AI provider through environment variables without code changes, while maintaining full backward compatibility for existing deployments using only
OPENAI_API_KEY.Other information:
New environment variables:
LLM_PROVIDER- openai (default), anthropic, google, azure, ollama, groqLLM_MODEL- Model name (defaults to gpt-4.1)LLM_TEMPERATURE- Temperature setting (defaults to 0.7)IMAGE_PROVIDER- openai (default), fal, stability, replicateIMAGE_MODEL- Image model name (defaults to dall-e-3)Required new dependencies:
