1. unsloth

   1 25 40,474 9.9 Python

   Fine-tuning & Reinforcement Learning for LLMs. 🦥 Train Qwen3, Llama 4, DeepSeek-R1, Gemma 3, TTS 2x faster with 70% less VRAM.

   

   Project mention: When Fine-Tuning Makes Sense: A Developer's Guide | news.ycombinator.com | 2025-06-01

   Lot's of tools for each of those separately (RAG and fine-tuning). We're working on combining them but it's not ready yet.

   You don't need a big GPU cluster. Fine-tuning is quite accessible via both APIs and local tools. Some suggestions:

   - getkiln.ai (biased, my tool): let's you try all of the below, and compare/eval the resulting models

   - API based tuning for closed models: OpenAI, Google Gemini

   - API based tuning for open models: Together.ai, Fireworks.ai

   - Local tuning for open models: https://unsloth.ai (can be run on Google Collab instances if you don't have local Nvidia GPUs).

   Project mention: Universal Personal Assistant with LLMs | dev.to | 2024-12-11

   Specialized projects that facilitate automatic document indexing and LLM invocation with the document content are gaining traction, for example PrivateGPT, QAnything, and LazyLLM. Another novelty is the integration of LLMs into applications and tools: The Semantic Kernel project aims to integrate LLM invocation during programming and inside the code itself.
