No model matched

Error message

No model matched: '${name}'

What it means

This error is thrown by the trae-solo `model` command when the model-switch name argument does not case-insensitively match any option label in Trae's opened model dropdown. The command first enumerates visible `.core-model-select-model-item[role="option"]` labels via page.evaluate, then finds an index whose label contains the requested substring; if findIndex returns -1 it closes the menu and throws CommandExecutionError, attaching the list of available labels as the detail. It exists to fail fast with actionable context instead of clicking an undefined option.

Solutions

1. Run the command with `--list` (or no name) to see the exact available labels and re-run with a matching substring.
2. Use a shorter, unambiguous substring of the label shown in the detail's available=[...] array.
3. Verify the model actually exists in this Trae workspace/plan; request access or pick another model.
4. Update the tooling if Trae renamed model entries so docs/aliases match new labels.

Example fix

// before
await cli('trae-solo', 'model', 'claude-3-5-sonnet');
// after
const opts = await cli('trae-solo', 'model', { list: true });
const target = opts.find(m => /claude/i.test(m.Model));
if (target) await cli('trae-solo', 'model', target.Model);

const listed = await cli('trae-solo', 'model', { list: true });
if (!listed.some(m => m.Model.toLowerCase().includes(name))) {
  throw new Error(`'${name}' not offered. Options: ${listed.map(m => m.Model).join(', ')}`);
}

const hasModel = (labels, name) =>
  Array.isArray(labels) && labels.some(l => typeof l === 'string' && l.toLowerCase().includes(name.toLowerCase()));

try {
  await cli('trae-solo', 'model', name);
} catch (e) {
  if (/No model matched/.test(e.message)) {
    console.warn('Available:', e.detail); // detail carries available=[...]
  } else throw e;
}

When it happens

Trigger: Calling `model <name>` where <name> is a substring not contained in any currently rendered model menu label — e.g. misspelling, wrong casing assumptions beyond case-insensitivity, a model not provisioned in this Trae workspace, or the menu rendering a truncated/renamed label set.

Common situations: Developers request a model by its marketing name (e.g. 'gpt-4o') while the Trae menu shows a different display label; org policies hide certain models; Trae updated and renamed menu entries; or the menu failed to fully render so only a partial label list was captured.
