# LLM Provider (REQUIRED)
# =============================================================================
# Honcho uses LLMs for memory extraction, summarization, dialectic chat, and
# dream consolidation. The server will fail to start without a provider configured.
#
# Quick start: set LLM_OPENAI_API_KEY below to use the built-in defaults.
# Text-generation features default to transport = "openai" and
# model = "gpt-5.4-mini". Embeddings default to transport = "openai" and
# model = "text-embedding-3-small". For OpenAI-compatible proxies
# (OpenRouter, Together, Fireworks, vLLM, Ollama, LiteLLM), override
# MODEL_CONFIG__MODEL and MODEL_CONFIG__OVERRIDES__BASE_URL on each feature
# section you want to route through that endpoint.
# Models must support tool calling (function calling).
#
# Supported transports: openai, anthropic, gemini
# Each transport picks up its API key from the corresponding LLM_*_API_KEY.
# Base URLs are set per-module via MODEL_CONFIG__OVERRIDES__BASE_URL.
