https://www.demixer.com/ has the same models implemented, though they don’t currently even describe that guitar model is available, but when you log in, it’s there. Guitar might be a bit worse than RipX (not confirmed)
“audioshake [had] the best guitar model [at some point] (its combined [paid only]), second place is deemix pro (electric guitar)”
"Demix launched a new v4 beta, and it can now process songs locally + new piano and strings models
the piano model is not bad at all, it sounds a bit thin/weak, but it detects almost all notes
hadn't found good songs to test the strings model yet, but it might be good too"
