Turn tool calls on for a model

What “not reported” means

A request that uses tools goes only to a machine that has said its model supports tool calls. Some engines don't publish that, and Saylek doesn't assume it. Until someone declares it, saylek model ls shows "tools not reported" under the model, the model takes requests without tools only, and a request with tools is refused with no_capable_model and "cause": "not_reported".

If the model runs on someone else's machine, ask the person who shared it with you to turn tool calls on, or send the request without tools.

Declare it

On the machine that serves the model, run saylek model ls and copy the command it prints under the model. It names that model's real URL and model id:

saylek model set URL \
  --declared-tool-calling \
  --model MODEL_ID

Declare it only if the model can call tools: requests with tools will be sent to it.

Check it worked

Run saylek model ls again: the "tools not reported" line under the model is gone. While the machine is connected, Saylek picks up the declaration within a minute. Then send the request with tools again.

If you declared it by mistake

saylek model set URL \
  --declared-tool-calling=false \
  --model MODEL_ID

This says the model does not support tool calls, which is not the same as never having declared it: requests with tools to that model are still refused, and the refusal no longer says "not reported".
