This means it's open-source, permitting use in multiple contexts like commercial projects without charge. ## Decision facts: peft - **Adopt for:** PEFT focuses on advanced techniques for efficiently tuning parameters in large models with Python. ## Choose when ### Choose llmfit if… - llmfit is primarily Rust; peft is Python. - License: llmfit is MIT, peft is Apache-2.0. - Requirements: Min 4 GB RAM; Built for Rust environments; No explicit dependency on Docker or other container runtimes. - Tags unique to llmfit: skill, mlx, localai, gguf. - llmfit ships Docker support for self-hosted deployment. - - When you need to quickly identify compatible machine learning models for your specific hardware configuration without manual research. llmfit automates this process, making it efficient. ### Choose peft if… - peft is primarily Python; llmfit is Rust. - License: peft is Apache-2.0, llmfit is MIT. - Tags unique to peft: fine-tuning, lora, python, parameter-efficient-learning. - When you need to fine-tune large language models but are constrained by compute resources or want to avoid overfitting. ## When NOT to use llmfit - - When the focus is on model development rather than discovery or management; llmfit centers on finding models based on hardware but does not provide deep integration into the training process itself. - - If real-time adaptability and dynamic hardware compatibility changes are needed, as llmfit operates with a more static approach tied to one command per execution. ## When NOT to use peft - If you require a tool that supports training from scratch, as PEFT is specifically designed for fine-tuning purposes only. - When working on models where the full fine-tuning of all parameters is feasible or preferred due to ample compute resources and no concern over overfitting. ## Common questions ### What is the difference between llmfit and peft? llmfit: Hundreds of models & providers. One command to find what runs on your hardware.. peft: State-of-the-art Parameter-Efficient Fine-Tuning.
