# The best free AI fine-tuning and training frameworks Every option in the catalog for when you need to train a model on your own data without a cluster — 7 AI fine-tuning and training frameworks, 7 of them free or freemium, with the pricing tier printed on every row. ## Stats - 7 tools listed - 7 free or freemium - 7 with no paid plan at all - 1 sub-categories covered ## FAQ ### What are the best free AI fine-tuning and training frameworks? Flocci AI Tools lists 7 of them, ordered free tiers first: LLaMA-Factory, AI Toolkit (Ostris), Axolotl, LitGPT and ms-swift (ModelScope). Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score. ### Which of these are completely free? 7 on this page are marked fully free with no paid plan at all: LLaMA-Factory, AI Toolkit (Ostris), Axolotl, LitGPT and ms-swift (ModelScope). The remaining 0 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up. ### How is this list ordered? Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else. ## Quick picks ### Which AI fine-tuning and training frameworks work in a browser with no install? LLaMA-Factory works in a browser tab with no install needed — just open the site and go. 1 of the 7 free AI fine-tuning and training frameworks listed here are browser-based. ### Which AI fine-tuning and training frameworks can you self-host or run offline? Axolotl, LitGPT, ms-swift (ModelScope), TRL (Hugging Face) and Unsloth can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 5 of the 7 free AI fine-tuning and training frameworks here run offline. ## Tools - [LLaMA-Factory](https://aitools.flocci.in/tool/llama-factory) — Free — Zero-code Web UI (LLaMA Board) for fine-tuning 100+ open models without writing training scripts - [AI Toolkit (Ostris)](https://aitools.flocci.in/tool/ai-toolkit-ostris) — Free — All-in-one trainer for LoRAs on diffusion and video models (FLUX, Wan and more) - [Axolotl](https://aitools.flocci.in/tool/axolotl) — Free — Config-file-driven fine-tuning workflow (YAML) covering LoRA, QLoRA, full fine-tuning, preference tuning and RL - [LitGPT](https://aitools.flocci.in/tool/litgpt) — Free — Clean from-scratch implementations of 20+ LLMs for pretraining, fine-tuning and deployment - [ms-swift (ModelScope)](https://aitools.flocci.in/tool/ms-swift-modelscope) — Free — Fine-tuning and deployment framework supporting hundreds of LLMs and multimodal models - [TRL (Hugging Face)](https://aitools.flocci.in/tool/trl-hugging-face) — Free — Post-training library covering SFT, DPO, GRPO and reward modeling for open LLMs - [Unsloth](https://aitools.flocci.in/tool/unsloth) — Free — Fine-tunes LLMs, diffusion, TTS and embedding models 2x faster with ~70% less VRAM than standard Hugging Face training --- Source: Flocci AI Tools — https://aitools.flocci.in/best/best-fine-tuning-training-frameworks Facts last verified: October 2026
