Cloud LLM Fallback (Anthropic Claude)

For hardware environments that cannot comfortably host a 3B+ LLM locally, AI Friend provides an optional, provider-agnostic Cloud LLM Fallback adapter.

Configuration

In your .env file, set:

LLM_PROVIDER=anthropic
ANTHROPIC_API_KEY=sk-ant-api03-...
ANTHROPIC_MODEL=claude-3-5-sonnet-20241022

Endocrine Parameter Translation

Unlike simple LLM wrappers, the AnthropicClient adapter (backend/app/llm/anthropic_client.py) translates internal affective endocrine states into cloud API sampling parameters:

• temperature is modulated by Cortisol ($0.3 \leftrightarrow 0.9$).
• top_p is modulated by Dopamine ($0.6 \leftrightarrow 0.98$).
• max_tokens is bounded by Fatigue.
• System prompts carry the identical 3-Tier Persona boundary and friction directives.

Privacy Notice

[!WARNING] Setting LLM_PROVIDER=anthropic transmits conversation turns over HTTPS to Anthropic servers. This is an explicit opt-in choice for users who trade local containment for higher inference speed or model intelligence.
