Fix: An Image Didn’t Generate
When a generation fails, the card’s title turns red and the card shows why. Find that message below, fix the cause, then run it again with Regenerate image (the circular arrows).
Every retry is a new request to an image model and counts toward usage. Gavana never retries a failed generation on its own, so a failure doesn’t cost you a second run unless you start one.
What the message means
| Message | What to do |
|---|---|
| Could not generate this image. Try again. | Run it again. If it keeps failing, change the prompt or the model |
| The image provider is rate limiting requests. Wait briefly, then retry. | Wait a minute, then retry |
| The image provider did not finish before the request timed out. Retrying is safe. | Retry |
| The image provider is temporarily unavailable. Try again in a moment. | Try again in a few minutes, or pick another model |
| The provider completed the request but did not return an image. Try again. | Retry |
| The image provider rejected this request. Change the prompt or references, then try again. | Reword the prompt or swap the reference images |
| This request isn’t supported by the selected model’s safety policy. Change the prompt or remove the reference image, then try again. | Change what you ask for, or remove the reference image |
| This model can’t use this reference image because it may contain a real person. Remove or replace it, then try again. | Use a reference image without a person, or another model |
| This image format isn’t supported by the selected model. Use a PNG, JPEG, or WebP image. | Upload the reference again as PNG, JPEG or WebP |
| This reference image is too large or invalid. Use a smaller PNG, JPEG, or WebP image. | Use a smaller PNG, JPEG or WebP image |
| This reference image can’t be loaded. Re-upload it or use an image saved in your Gavana account. | Upload the reference again, or pick one from your Assets |
| A message that a model takes up to a number of reference images | Remove the extra references it names, or pick another model |
| The image was generated but couldn’t be saved to this Canvas. Check your connection or storage access, then retry. | Check your connection, then retry |
| This Canvas was updated while Gavana was saving the generation. Try again in a moment. | Someone changed the canvas at the same moment. Retry |
| Your Gavana session has expired. Refresh the page and sign in again. | Reload the page and sign in |
| Your Gavana runtime couldn’t produce an image. Retry, or choose a connected cloud model. | The computer you connected couldn’t make it. Retry, or choose another model |
| Request canceled | You stopped the generation. Start it again if you still want it |
If the card already had a picture, a failed run keeps it and shows the reason over it, or Generation failed — showing the previous result.
A saved API key was refused
If you or your workspace owner saved a provider API key, that key pays for that provider’s models before Gavana credit. When the provider refuses the key, the message starts with Your saved image key or The workspace owner’s image key, says the key was rejected by the provider, has no available credit or quota, or is temporarily rate limited, and ends with This request has stopped; no other key was charged by a fallback.
- Your own key: open Settings, then AI connections, and top up, re-test or replace the key. Retrying can use another key that is still available, including the workspace owner’s shared key.
- The workspace owner’s key: ask the owner to check their key before you retry.
- Rate limited: the key works again after a short cooldown.
Check whether you can generate at all
Open Settings, then AI connections. The Gavana image generation section says where you stand:
| Status | Meaning |
|---|---|
| Available with your Gavana allowance. | You can generate with Gavana’s models |
| Your image allowance is unavailable or used up. Contact Gavana to restore access. | Gavana credit can’t pay for your images. A saved key for a model’s provider still works |
| Gavana credit for image generation is not set up yet. A saved key for a model’s provider still works. | Only models with a saved key can generate |
The model list on an image card says the same thing at its foot, for example Your Gavana image budget is unavailable. Models with a saved API key still work.
