Error message

imageModel

What it means

Baseten's provider does not implement image generation, so provider.imageModel is a stub that always throws NoSuchModelError with modelType 'imageModel'. Any request for an image model from this provider fails.

Solutions

1. Use a provider with image support, e.g. createOpenAI(...).imageModel('dall-e-3') or other image-capable providers.
2. Check provider capability before routing (hasImageModel check in your code).
3. Use Baseten only for chat and embedding models.

Example fix

// before
const imageModel = baseten.imageModel('flux');
// after
import { createOpenAI } from '@ai-sdk/openai';
const imageModel = createOpenAI({ apiKey }).imageModel('dall-e-3');

try {
  const imageModel = provider.imageModel('flux');
} catch (e) {
  if (NoSuchModelError.isInstance(e) && e.modelType === 'imageModel') {
    const imageModel = createOpenAI({ apiKey }).imageModel('dall-e-3'); // fallback provider
  }
}

When it happens

Trigger: Calling createBaseten({ ... }).imageModel('any-id'), or using generateImage/streamImage with a Baseten provider instance.

Common situations: Assuming Baseten supports all model modalities; generic code paths that route image generation to the configured provider.
