Model "${options.model}" not found

Error message

Model "${options.model}" not found

What it means

`createCompressSession()` resolves the user-supplied model selector through `resolveCliModel` against a freshly built `ModelRegistry`; when resolution returns an error or no model, this Error is thrown naming the selector. The compress run cannot start without a concrete model because token metrics and generation both depend on it.

Solutions

1. Run with a valid selector — check available ids (e.g. `omp models` / the model registry listing) and fix the spelling
2. Omit `options.model` entirely so the session uses whatever model the settings configure by default
3. Verify provider auth is configured so the intended model appears in the refreshed registry

Example fix

// before
await createCompressSession({ model: "claude-4-sonnet", ... }); // not found
// after
await createCompressSession({ model: "anthropic:claude-sonnet-4", ... }); // or omit model

const registry = new ModelRegistry(authStorage);
await registry.refresh();
const resolved = options.model ? resolveCliModel({ cliModel: options.model, modelRegistry: registry, settings }) : undefined;
if (resolved?.error || resolved?.model === undefined) {
  // surface resolved?.error and stop before creating the session
}

function isResolvableModel(r: { error?: string; model?: unknown }): r is { error?: undefined; model: NonNullable<typeof r.model> } {
  return !r.error && r.model != null;
}

try {
  await createCompressSession(options);
} catch (err) {
  if (err instanceof Error && /^Model ".*" not found$/.test(err.message)) {
    // fall back to settings default (omit options.model) or prompt the user for a valid id
  } else throw err;
}

When it happens

Trigger: Passing `options.model` as a selector string that matches no model in the registry — e.g. a misspelled id (`"claude-4-sonnet"`), a deprecated/removed model id, or a provider whose auth/catalog entries are absent after `modelRegistry.refresh()`.

Common situations: Typo in a CLI `--model` flag or config file; model renamed upstream so an old pinned id no longer resolves; missing provider API keys so the model is filtered out of the registry; offline catalog refresh.
