This is a Exl2 quantized version of psyonic-cetacean-20B

Please refer to the original creator for more information.

Calibration datasets:


  • main: Measurement files
  • 4bpw: 4 bits per weight
  • 5bpw: 5 bits per weight
  • 6bpw: 6 bits per weight

The bpws with the (-pippa) suffix indicate that the cleaned PIPPA dataset was used for calibration instead of wikitext.


  • 6bpw is recommended for the best quality to vram usage ratio (assuming you have enough vram).
  • Please ask for more bpws in the community tab if necessary.
