CORE supports multiple AI model providers. Set your provider and API key in your environment variables, then choose which models to use for chat and embeddings.

​
Configuration

Two environment variables control which provider and model CORE uses: 
CHAT_PROVIDER=openai       # openai | anthropic | google | azure | ollama
MODEL=gpt-5-2025-08-07     # model ID for the selected provider
