Does OpenCode need a plugin or a fork?

No. Add the router as an OpenAI-compatible provider in opencode.json, or launch with these variables. The router is a standard endpoint; the tool is unchanged.

Which model does the tool get?

Whatever it asks for. The name auto lets the router choose per turn under your policy; a model id pins it and still routes among its providers; a workspace alias maps the tool's own default name to either.

What does the router add that the tool does not have?

Any provider the policy allows. Budgets and redaction in front of every turn. A trace per call.

Can I use my own provider keys?

Yes - connect them under Model providers and the router executes on your accounts; model usage is billed by the provider, the platform meters requests.

OpenCode through the router

OpenCode through the router: any provider, one policy.

OpenCode takes an OpenAI-compatible provider; make it OpenSmartRoute and every turn is governed, priced and traced, with auto choosing the model when you let it.

One commandbash

pip install opensmartroute
osr login                      # once: a browser sign-in, or --token osr_live_...
osr run opencode          # OpenCode starts with the router as its endpoint

Or by hand - opencodebash

export OPENAI_BASE_URL=https://api.opensmartroute.ai/v1
export OPENAI_API_KEY=$OSR_API_KEY
opencode

OpenCode speaks the OpenAI API; the router serves chat completions and the Responses API at /v1 with streaming, tools and structured output passed through.

Verify

The first turn is on the activity page.

Send one message from the tool and read the row: the model that answered, the cost, the confidence and a link to the full trace with the alternatives and the policy decisions.

verify.shbash

# the tool's next turn is on the activity page with its cost, model and trace
curl -s https://api.opensmartroute.ai/api/v1/activity?limit=3 -H "Authorization: Bearer $OSR_API_KEY"
