Rev.ai does not provide image models

Error message

Rev.ai does not provide image models

What it means

The Rev.ai provider does not implement image models, so its provider object throws NoSuchModelError whenever imageModel() is called. Rev.ai is a speech-to-text service; the provider only supports transcription (and related) capabilities. This error is thrown eagerly to give a clear message instead of failing later with an unclear error.

Solutions

1. Do not use the revai provider for image generation; switch to a vision-capable provider such as @ai-sdk/openai
2. Call provider.transcriptionModel(...) instead — transcription is Rev.ai's supported capability
3. Guard capability checks before calling imageModel on an arbitrary provider

Example fix

// before
const model = revai.imageModel('dalle');
// after
const model = revai.transcriptionModel('general');

function supportsImageModels(provider) {
  try { provider.imageModel('probe'); return false; } catch (e) { return !(e && e.name === 'NoSuchModelError'); }
}
// simpler: consult provider docs/capabilities before wiring

function isNoSuchModelError(e) {
  return typeof e === 'object' && e !== null && e.name === 'NoSuchModelError' && 'modelType' in e;
}

let model;
try { model = provider.imageModel(id); }
catch (e) { if (e.name === 'NoSuchModelError') model = fallbackProvider.imageModel(id); else throw e; }

When it happens

Trigger: Calling provider.imageModel('some-model') or passing the revai provider to an API that resolves an image model (e.g. generateImage with provider.imageModel), or using a default image model resolution path.

Common situations: Developers assume the provider supports the full LanguageModel surface and plug it into generateImage or a multi-capability pipeline; config mistakes where the wrong provider is wired for image generation.
