ezexl3 0.0.3

Single-command EXL3 quantization + measurement + reporting pipeline

ezexl3

ezexl3 is a simple, single-command exl3 repo generator.

It wraps the exllamav3 quantization and evaluation workflow into a tool that:

• Runs batch quantization easily (resume / skip supported)
• Measures PPL + KL div, recording data to CSV
• Generates a HuggingFace-ready README.md with your measurements using customizable templates
• Embeds an SVG graph from the merged measurement CSV in the README

all with one command.

Installation

This tool requires a local installation of exllamav3.

# 1. Make sure you have exllamav3 installed.

# 2. Clone and install ezexl3
git clone https://github.com/UnstableLlama/ezexl3
cd ezexl3
pip install -e .

Usage

1. Quantize a full repository

Run the entire pipeline (quantize -> measure -> README):

ezexl3 repo -m /path/to/base_model -b 2,3,4,5,6 -d 0,1 -t basic

Then ezexl3 automatically:

• Quantizes the model to all indicated bitrates, saved under subdirectories in the base model folder.

• Measures PPL and KL div and saves to a modelMeasured.csv in the base model folder, and makes a stylish dark mode SVG graph with the data.

• Generates a README.md for a HuggingFace exl3 quantization repo in the base model folder. (with optional customizable templates)

2. Standalone subcommands

If you only want to run specific stages:

# Quantize only
ezexl3 quantize -m /path/to/base_model -b 2,3,4,5,6 -d 0,1

# Measure only
ezexl3 measure -m /path/to/base_model -b 2,3,4,5,6 -d 0,1

# Generate README only (from existing CSV)
ezexl3 readme -m /path/to/base_model -t fire

3. Template System

You can customize the generated README by providing a template name via --template or -t. Templates are stored in the templates/ directory.

The system is flexible with naming. For example, -t fire will search for:

• templates/fire.md
• templates/fireTemplateREADME.md
• templates/fireREADME.md
• templates/fireTemplate.md

If no template is specified, it defaults to basicTemplateREADME.md.

Easily generate your own custom template with AI assistance!

Copy and paste any TemplateREADME.md into your favorite LLM (Gemini, Claude, ChatGPT) along with this example prompt, followed by your own description:

Take this template, keep the main layout and variables, and modify it aesthetically based on my following prompts. Preserve all of the labels and title strings, only change the aesthetic, not the words or numbers:

*Make it dark and understated, high contrast, professional, metallic.*

Then save the resulting output in /ezexl3/templates/ as mynewTemplateREADME.md

Use your template with

ezexl3 repo -m /path/to/base_model -t mynew -b 2,3,4,5,6 -d 0,1

4. Advanced: Passthrough Flags

You can pass custom arguments directly to the underlying quantization (multiConvert) or measurement scripts using the --quant-args and --measure-args flags.

Important: These flags require a double-dash -- delimiter to separate the passthrough block from the rest of the arguments.

# Pass custom calibration dataset to quantization
ezexl3 repo -m /path/to/model -b 4.0 --quant-args -- -pm

# Pass custom rows/device settings to measurement
ezexl3 repo -m /path/to/model -b 4.0 --measure-args -- -r 200 -d 0

Common Use Cases:

• Quantization: -pm (MoE speedup), -ss (shard size), -nr (no-rope-scaling). If using -r/--device-ratios, provide one positive ratio per device in -d/--devices.
• Measurement: -r / --rows (number of rows for PPL), -d / --device / --devices (specific evaluation device list).

Note: passthrough blocks consume remaining args until another passthrough block starts, so keep normal CLI flags (like --no-readme) before --measure-args -- ....

Deprecated/legacy flags:

• --exllamav3-root is deprecated and ignored.
• repo --schedule currently supports queue behavior only (--schedule static is accepted but ignored).
• repo --no-meta is accepted but currently ignored.

5. Headless Mode

For automated pipelines, use the --no-prompt (or -np) flag to skip interactive metadata collection for the README. It will use sensible defaults based on the model directory name and your environment.

ezexl3 repo -m /path/to/model -b 4.0 --no-prompt
