${editUnsupportedProvider} image generation is text-to-image

Error message

${editUnsupportedProvider} image generation is text-to-image only and cannot edit input images. Configure an edit-capable provider (openai, openai-codex, antigravity, xai, openrouter, gemini) or retry without input images.

What it means

Some configured image providers are text-to-image only and cannot consume input images for editing. When the request includes input images but the only credentialed provider lacks edit support, the tool throws naming that provider and listing edit-capable alternatives (openai, openai-codex, antigravity, xai, openrouter, gemini).

Solutions

Add credentials for an edit-capable provider listed in the message (e.g. export OPENAI_API_KEY or GEMINI_API_KEY).
Retry without input images if pure text-to-image output is acceptable.
Perform the edit with a different tool/workflow (e.g. local image editor) and use this provider only for generation.
Verify which provider your config routes image-gen to before passing reference images.

Example fix

// before
image_gen({ prompt: "remove background", images: ["attachment://1"] }) // only deepinfra credentialed
// after
export OPENAI_API_KEY=sk-...  // edit-capable provider
image_gen({ prompt: "remove background", images: ["attachment://1"] })

Defensive patterns

Strategy: validation

Validate before calling

const EDIT_CAPABLE = new Set(['openai','openai-codex','antigravity','xai','openrouter','gemini']);
if (images.length > 0 && !EDIT_CAPABLE.has(activeProvider)) {
  throw new Error(`${activeProvider} cannot edit images; configure an edit-capable provider or drop input images`);
}

Try / catch

try {
  await imageGen({ images, ...params });
} catch (err) {
  if (err instanceof Error && err.message.includes('text-to-image only')) {
    // retry without images or switch to an edit-capable provider
    return imageGen({ ...params, images: [] });
  }
  throw err;
}

Prevention

Track per-provider edit capability alongside credentials
Only attach reference images when the routed provider supports edits
Document provider capabilities in config so routing picks edit-capable ones for edit jobs

When it happens

Trigger: Calling image-gen in edit mode (resolvedImages.length > 0) where the sole credentialed provider is edit-unsupported, at image-gen.ts:1761. Only fires when that provider attempt produced no other failure (failures.length === 0).

Common situations: Only DEEPINFRA_API_KEY (or another text-to-image-only provider) configured while asking to modify an attached image; assuming every image model supports img2img; switching API keys without rechecking edit capability.
