image edit is not supported for {custom_llm_provider}

Error message

image edit is not supported for {custom_llm_provider}

What it means

image_edit routes through ProviderConfigManager.get_provider_image_edit_config(); when no BaseImageEditConfig exists for the provider/model (litellm/images/main.py:827-833), litellm raises ValueError — the provider does not support the image-edit endpoint in this version.

Solutions

1. Upgrade litellm — image-edit provider coverage (gpt-image-1, bedrock, BFL, azure) expanded across releases
2. Verify model spelling and provider prefix against the docs (e.g. 'azure/gpt-image-1')
3. Switch to a provider with edit support (OpenAI gpt-image-1/dall-e-2, Bedrock, Black Forest Labs)
4. For bedrock/black_forest_labs, ensure model is set (separate guard exists)

EDIT_CAPABLE_PREFIXES = ("openai/", "azure/", "bedrock/", "black_forest_labs/", "vertex_ai/")

def supports_image_edit(model: str) -> bool:
    return model.startswith(EDIT_CAPABLE_PREFIXES) or model.split("/", 1)[0] in {p.rstrip("/") for p in EDIT_CAPABLE_PREFIXES}

try:
    r = litellm.image_edit(model=m, image=img, prompt=p)
except ValueError as e:
    if "image edit is not supported" in str(e):
        raise UnsupportedEditProvider(m) from e
    raise

When it happens

Trigger: Calling litellm.image_edit(model='openai/gpt-image-1'|'azure/...'|'vertex_ai/...') with a provider whose image-edit config is not registered in the installed version; or a model string that doesn't resolve to a config.

Common situations: Using a provider for edit that only supports generation; older litellm versions before edits were added for a provider; typos in model names preventing config match.
