Image generation not supported by the model yet

Error message

Image generation not supported by the model yet

What it means

Thrown by PerplexityAI.getImageModel as UnsupportedOperationException. Perplexity is a text/chat-only provider and has no image generation capability; getImageModel is intentionally unimplemented.

Solutions

  1. Route image generation to an image-capable provider (StabilityAI, OpenAI).
  2. Guard getImageModel() calls with a capability check (e.g. getModelProvider()) before invocation.
  3. Correct the llmProvider on the image task input.
Defensive patterns

Strategy: validation

Validate before calling

if ("perplexity".equals(model.getModelProvider())) {
    throw new IllegalArgumentException(
        "Perplexity does not support image generation");
}
ImageModel img = model.getImageModel();

Type guard

boolean supportsImages(AIModel m) {
    return !"perplexity".equals(m.getModelProvider());
}

Try / catch

try {
    ImageModel img = model.getImageModel();
} catch (UnsupportedOperationException e) {
    // provider lacks image generation; switch provider
}

Prevention

When it happens

Trigger: Calling getImageModel() on a PerplexityAI instance, or routing an image-generation task to the perplexity provider.

Common situations: An image task configured with llmProvider=perplexity, or generic code that calls getImageModel() on every AIModel without checking capabilities.
