Description:
Are there programmatic way to list model like black-forest-labs/flux.2-max?

What I've Tried:
I hit https://openrouter.ai/api/v1/models and found no image(image-only) generation model.

API/Model: black-forest-labs/flux.2-max

I'm an AI assistant - my answers may be incorrect and I cannot see screenshots. Please verify information with the OpenRouter docs.

To programmatically list models that support image generation, use the /models API endpoint and filter for models where "image" is present in their output_modalities. According to the documentation:

"OpenRouter supports image generation through models that have "image" in their output_modalities... You can find image generation models in several ways... use the Models page and filter by output modalities to find models capable of image generation."
Image Gen Guide

The API endpoint you should query is:

GET <https://openrouter.ai/api/v1/models>

Then, filter results client-side for models where:

"output_modalities": ["image", ...]

If models like black-forest-labs/flux.2-max are not returned, it's possible they are not currently listed via the public API. You can verify available image models on the OpenRouter Models page, filtering by output modalities ["image"] for the most up-to-date list.

"Not all models support image generation... Use the Models page to find available image generation models—filter by output modalities to see compatible models."
Image Models Docs

If you don't find the model via API, it might not be available for public programmatic query. In this case, check the models page or contact support for clarification.

Do you mean https://openrouter.ai/api/v1/models, I don't find black-forest-labs/flux.2-max there.

It's correct that the /api/v1/models endpoint does not currently return a listing for black-forest-labs/flux.2-max. Only two Black Forest Labs models are officially offered through OpenRouter at this time:

Both are listed on the Black Forest Labs models page, and those are the only available options for programmatic use through the OpenRouter API at this time. If flux.2-max is not appearing in the API list, it is not currently available for use via OpenRouter Black Forest Labs Models.

"Browse models from black-forest-labs... Black Forest Labs: FLUX.2 Flex ... Black Forest Labs: FLUX.2 Pro"

If you need to monitor new model availability, check the OpenRouter Models catalog regularly.

So in the future, will that(programmatic way to list image-gen-only model) be available?

I don't have specific documentation for future additions to the OpenRouter API, and there's no statement confirming that a programmatic way to list image-generation-only models will be available soon. For now, the best way to find current image-gen models is to use the OpenRouter Models page and filter by output modalities ["image"].

For updates on new API features, you should periodically check the OpenRouter docs or the #announcements channel in Discord. If you have a feature request, you can also contact mods in the Discord server.
