Set up cognee integrations

All integration config is environment variables (.env). The authoritative, always-current list with commented examples is .env.template at the repo root — check it before inventing variable names. Install the matching extra before switching a backend (e.g. pip install cognee[postgres]).

LLM providers

Default is OpenAI (LLM_API_KEY is all you need). To switch, set LLM_PROVIDER, LLM_MODEL, LLM_API_KEY, and (where relevant) LLM_ENDPOINT / LLM_API_VERSION:

• Azure OpenAI: LLM_PROVIDER=azure, LLM_MODEL=azure/gpt-4o-mini, endpoint + api version required.
• Gemini (no extra needed): LLM_PROVIDER=gemini, LLM_MODEL=gemini/gemini-2.0-flash-exp.
• Anthropic (cognee[anthropic]): LLM_PROVIDER=anthropic, model e.g. claude-3-5-sonnet-20241022.
• Ollama, local (cognee[ollama]): LLM_PROVIDER=ollama, LLM_ENDPOINT=http://localhost:11434/v1, and set the embedding block + HUGGINGFACE_TOKENIZER too.
• Custom / OpenRouter / vLLM: LLM_PROVIDER=custom with the provider's OpenAI-compatible endpoint.
• AWS Bedrock (cognee[aws]): LLM_PROVIDER=bedrock + AWS credentials/region.
