SwarmUI's metadata updates directly modify the metadata record in the safetensors file, changing hash. Consider supporting AutoV3 hashes, which ignore the metadata record(s).

Have you read document?

Yes.

Describe Issue

SwarmUI (ex-StableSwarm) allows the user to update the metadata of model, but it stores the updates directly in the safetensors files. This breaks SHA256 and AutoV2 hashes, and for users who share models between applications, this may cause those users to lose the ability to pull new or updated metadata using your extension.

AutoV3 hashes, however, ignore the metadata and hash only the tensor information.

Civitai API's model hash endpoint has support for AutoV3 lookups, even though the official API docs don't include that yet.

Please consider adding support for the newer AutoV3 hash standard.

Thanks

I'll look into it. I believe the hashing function I use can already skip hashing headers, I just need to pass a flag to the function and format for autov3.

On a side note, can we all just appreciate that Civitai's API documentation is eternally out of date and/or missing documentation entirely? I'm guessing autov3 support isn't actually that new.

Looks like they added AutoV3 to their internal scanner 8mo ago. I'm assuming API followed not too long after.

(Mostly adding so you have an additional reference for the algorithm.)
