1. oumi
Easily fine-tune, evaluate and deploy gpt-oss, Qwen3, DeepSeek-R1, or any open source LLM / VLM!
What sets it apart: vs Axolotl/LLaMA-Factory: Complete end-to-end platform covering data synthesis, training (up to 405B params), evaluation, and deployment with one consistent API - not just a fine-tuning tool
Best for: ML teams training and fine-tuning foundation models end-to-end; Research groups needing a unified platform from data to deployment; Organizations scaling model training across multiple clouds
2. Unsloth
Unsloth Studio is a web UI for training and running open models like Qwen, DeepSeek, gpt-oss and Gemma locally.
What sets it apart: Unlike Axolotl (config-based, no speed optimization) or Hugging Face TRL (standard VRAM usage), Unsloth uses custom Triton kernels to deliver 2x faster fine-tuning with 70% less VRAM — making it possible to fine-tune 7B+ models on a single consumer GPU.
Best for: Developers and researchers fine-tuning open-source LLMs on consumer GPUs (RTX 30/40/50 series); Teams doing RLHF/GRPO training who need maximum VRAM efficiency
