Best for	ML engineers fine-tuning open models Research teams needing reproducibility Practitioners running multi-GPU training	Researchers and students fine-tuning open models Indie developers and startups on a budget ML engineers optimizing training cost
Pros	Free and open source under MIT/Apache Single YAML config makes runs reproducible Supports LoRA, QLoRA, and full fine-tuning Multi-GPU training with FSDP and DeepSpeed Very active development and new model support	Free, permissive Apache 2.0 open-source core Large speedups and major memory savings Runs on consumer and free-tier GPUs Huge, active community and adoption Integrates with Hugging Face, Colab, and PyTorch
Cons	Requires ML and infrastructure expertise No managed UI or hosted service in the core project You supply and pay for your own GPUs Debugging distributed runs can be complex Not aimed at non-technical users	Requires ML knowledge to use effectively Multi-GPU/multi-node training needs paid tiers Cited speedups/memory savings are configuration-dependent Limited built-in team collaboration features You manage your own compute and workflow
