About Soup CLI
Soup CLI is an innovative, open-source developer tool designed to democratize LLM fine-tuning by enabling developers to train large language models on modest consumer hardware. Specifically, Soup CLI makes it possible to fine-tune an 8B LLM using just a 4 GB laptop GPU.
Because Low-Rank Adaptation (LoRA) keeps the base model frozen—meaning it is read from and never written to—Soup CLI keeps the base model in system RAM and streams it into the GPU one decoder layer at a time. This reduces peak VRAM consumption to just a single layer instead of holding the entire model in memory. Tested on an RTX 3050 Laptop 4 GB GPU, Llama-3.1-8B trains at an impressive 119.6 tokens/sec while maintaining a peak usage of only 3.32 GB.
Featuring a streamlined workflow requiring just one YAML configuration file and a single command, Soup CLI supports multiple training methods including SFT, DPO, GRPO, and KTO, alongside built-in capabilities for evaluation, gating, and model export. Distributed under the Apache-2.0 license, the project prides itself on radical transparency, publishing all performance numbers—including experimental data that didn't make the cut.
Pros of Soup CLI
- Fine-tune an 8B LLM (like Llama-3.1-8B) on a modest 4 GB laptop GPU
- Extremely memory efficient by streaming the frozen base model layer-by-layer from system RAM
- Simple user experience with a single YAML configuration file and one-command execution
- Supports multiple training methods including SFT, DPO, GRPO, and KTO, plus eval, gating, and export
- Open-source (Apache-2.0) with transparent performance data and published metrics
Cons of Soup CLI
- Requires sufficient system RAM to hold the base model while streaming to the GPU
- Performance heavily relies on system memory bandwidth for layer streaming
- Limited to hardware configurations compatible with the CLI's memory-streaming architecture
Frequently Asked Questions
What is Soup CLI?
Soup CLI is an open-source developer tool that allows users to fine-tune large language models (such as an 8B LLM) on a low-end 4 GB laptop GPU by leveraging a layer-by-layer memory streaming approach.
How does Soup CLI reduce VRAM usage?
Because LoRA keeps the base model frozen and read-only, Soup CLI stores the base model in system RAM and streams it into the GPU one decoder layer at a time. This keeps peak VRAM consumption down to just a single layer rather than the whole model.
What training methods and features are supported?
Soup CLI supports SFT (Supervised Fine-Tuning), DPO, GRPO, and KTO. It also includes built-in evaluation, model gating, and model export functionalities, all configured via a single YAML file and executed with one command.
Is Soup CLI open-source?
Yes, Soup CLI is released under the Apache-2.0 open-source license.
About WebMotion
WebMotion is a highly technical, open-source tool designed for browser-native video composition. It fundamentally shifts how programmatic video is created by eliminating the need for heavy server-side infrastructure like render farms, headless Chrome instances, or even FFmpeg. Instead, it leverages the DOM and the modern WebCodecs API to compose and encode MP4 videos directly within the user's browser. The core philosophy of WebMotion is deterministic rendering. Every single frame generated by the tool is a pure function of its frame index, meaning developers have absolute, frame-by-frame control over the output. This makes it an exceptionally powerful utility for developers and creators looking to programmatically generate data visualizations, generative art, or automated marketing videos using familiar web technologies (HTML/CSS/JS) entirely client-side.
Pros of WebMotion
- Operates entirely in the browser, eliminating server costs and the need for complex backend rendering infrastructure.
- Utilizes modern WebCodecs for fast, efficient, and native MP4 encoding.
- Completely open-source, allowing developers to inspect, modify, and host the tool themselves.
Cons of WebMotion
- Requires a solid understanding of web development and programmatic rendering, making it inaccessible to non-technical users.
- Performance and rendering speed are heavily reliant on the user's local machine and browser capabilities rather than scalable cloud servers.
Frequently Asked Questions
Do I need to install FFmpeg or run a backend server to use WebMotion?
No. WebMotion is entirely browser-native. It uses the WebCodecs API to encode video directly in the DOM, so there is no need for FFmpeg, headless Chrome, or a backend render farm.
What does it mean that 'every frame is a pure function of the frame index'?
It means the rendering is deterministic. You write code that defines exactly what a frame should look like based solely on its sequence number (e.g., Frame 1, Frame 2), ensuring perfect, predictable, and repeatable animations.
