c4ai-command-r-v01 - EXL2 4.0bpw

This is a 4.0bpw EXL2 quant of CohereForAI/c4ai-command-r-v01

Details about the model can be found at the above model page.

EXL2 Version

These quants were made with exllamav2 version 0.0.18. Quants made on this version of EXL2 may not work on older versions of the exllamav2 library.

If you have problems loading these models, please update Text Generation WebUI to the latest version.

RP Calibrated

The rpcal quants were made using data/PIPPA-cleaned/pippa_raw_fix.parquet for calibration.

Perplexity Scoring

Below are the perplexity scores for the EXL2 models. A lower score is better.

Command-R-Plus Template

This is the Command-R-Plus template yaml that was used in EQ bench(which uses Text Generation Web UI yaml templates). It adds BOS_TOKEN into the starter prompt.

text-generation-webui/instruction-templates/Command-R-Plus.yaml:

yaml

instruction_template: |-

      {%- set loop_messages = messages[1:] -%}
