the file weight.bin located under Library/Application Support/coreMLCache/rxl_embed-v1-fp16-77x768-mlc.tz/weights/ has grown to 1TB and I need to free some space, what can I do?

Out of the blue I lost almost 1TB of space on my MACBOOK PRO M1 and have found that all went to the weight.bin file.

I assume spotlight has indexed several external drives that it was not supposed to index and now I have been left with no space to work.

I could delete it hoping spotlight will index again the drives I want (already selected now under spotlight privacy), but I am not sure if that could create unintended consequences.

Can anyone enlighten me?

Thanks
