Configure providers

The graft map is vendor-neutral. Only the LLM-written parts, from trail build --deep, go through your provider key. Settings keep their GRAFT_ names.

Choose a provider

Set GRAFT_PROVIDER to one of:

Value	Use it for
`openai`	Any OpenAI-compatible endpoint
`anthropic`	The native Anthropic API
`litellm`	A LiteLLM gateway that speaks the OpenAI-compatible format
`orcarouter`	An OrcaRouter gateway that speaks the OpenAI-compatible format

Then set your key and model:

export GRAFT_PROVIDER=anthropic
export GRAFT_API_KEY=<your key>
export GRAFT_MODEL=<model>

Point at an OpenAI-compatible endpoint

For the openai wire format, set GRAFT_BASE_URL to point at OpenRouter, Fireworks, Groq, a LiteLLM proxy, a local server, or OpenAI itself:

export GRAFT_PROVIDER=openai
export GRAFT_API_KEY=<your key>
export GRAFT_MODEL=<model>
export GRAFT_BASE_URL=<endpoint URL>

Pass settings on the command line

trail build --deep --provider <provider> --model <model> --api-key <key> --base-url <url>
