# c4ai-command-r-v01 - EXL2 4.0bpw

This is a 4.0bpw EXL2 quant of [CohereForAI/c4ai-command-r-v01](https://huggingface.co/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 working 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. It adds BOS_TOKEN into the starter prompt.

```yaml
instruction_template: |-
  {%- if messages[0]['role'] == 'system' -%}
      {%- set loop_messages = messages[1:] -%}
      {%- set system_message = messages[0]['content'] -%}
  {%- elif false == true -%}
      {%- set loop_messages = messages -%}
      {%- set system_message = 'You are Command-R, a brilliant, sophisticated, AI-assistant trained to assist human users by providing thorough responses. You are trained by Cohere.' -%}
  {%- else -%}
      {%- set loop_messages = messages -%}
      {%- set system_message = false -%}
  {%- endif -%}
  {%- if system_message != false -%}
      {{ '<BOS_TOKEN><|START_OF_TURN_TOKEN|><|SYSTEM_TOKEN|>' + system_message + '<|END_OF_TURN_TOKEN|>' }}
  {%- endif -%}
  {%- for message in loop_messages -%}
      {%- set content = message['content'] -%}
      {%- if message['role'] == 'user' -%}
          {{ '<|START_OF_TURN_TOKEN|><|USER_TOKEN|>' + content.strip() + '<|END_OF_TURN_TOKEN|>' }}
      {%- elif message['role'] == 'assistant' -%}
          {{ '<|START_OF_TURN_TOKEN|><|CHATBOT_TOKEN|>'  + content.strip() + '<|END_OF_TURN_TOKEN|>' }}
      {%- endif -%}
  {%- endfor -%}
  {%- if add_generation_prompt -%}
      {{ '<|START_OF_TURN_TOKEN|><|CHATBOT_TOKEN|>' }}
  {%- endif -%}

```

### Perplexity Script

This was the script used for perplexity testing.

```bash
#!/bin/bash

# Activate the conda environment
source ~/miniconda3/etc/profile.d/conda.sh
conda activate exllamav2

# Set the model name and bit size
MODEL_NAME="c4ai-command-r-v01"
BIT_PRECISIONS=(8.0 7.0 6.0 5.0 4.5 4.0 3.5 3.0)

# Print the markdown table header
echo "| Quant Level | Perplexity Score |"
echo "|-------------|------------------|"

for BIT_PRECISION in "${BIT_PRECISIONS[@]}"
do
  MODEL_DIR="models/${MODEL_NAME}_exl2_${BIT_PRECISION}bpw"
  # MODEL_DIR="models/${MODEL_NAME}_exl2_${BIT_PRECISION}bpw-rpcal"
  if [ -d "$MODEL_DIR" ]; then
    output=$(python test_inference.py -m "$MODEL_DIR" -gs 22,24 -ed data/wikitext/wikitext-2-v1.parquet)
    score=$(echo "$output" | grep -oP 'Evaluation perplexity: \K[\d.]+')
    echo "| $BIT_PRECISION | $score |"
  fi
done
