# ─── LLM Fallback (entity + relation extraction) ────────────────
# ctxgraph extracts locally via ONNX (GLiNER + GLiREL).
# When local confidence is low, it makes ONE LLM call.
# Set ONE of these API keys to enable the LLM fallback.

# Option 1: OpenAI (recommended — best quality with gpt-4o-mini)
OPENAI_API_KEY=

# Option 2: Anthropic (Claude models)
# ANTHROPIC_API_KEY=

# Option 3: OpenRouter (access to 200+ models)
# OPENROUTER_API_KEY=

# Option 4: Custom OpenAI-compatible endpoint (Ollama, LiteLLM, etc.)
# CTXGRAPH_LLM_KEY=
# CTXGRAPH_LLM_URL=              # e.g. http://localhost:11434/v1/chat/completions
# CTXGRAPH_LLM_MODEL=            # e.g. qwen2.5:7b

# ─── Storage ────────────────────────────────────────────────────
CTXGRAPH_DB=                     # default: .ctxgraph/graph.db
CTXGRAPH_MODELS_DIR=             # default: ~/.cache/ctxgraph/models

# ─── Optional ───────────────────────────────────────────────────
# CTXGRAPH_NO_EMBED=1            # disable semantic search (FTS5 only)
