The honest brief
Predibase
Its open-source LoRAX engine serves dozens of fine-tuned LoRA adapters on one GPU, so shipping many per-task fine-tunes stays cheap.
- Fine-tune + serve in one place
- End-to-end RFT workflow
- Many adapters per GPU (LoRAX)
- SaaS or your own VPC
- Enterprise-priced
- Now tied to Rubrik's roadmap
- Open-source models only
Unsloth
Hand-written CUDA kernels roughly halve fine-tuning time and VRAM, so 7B–13B models train on a single consumer GPU — free and Apache-2.0.
- LoRA, QLoRA, and full fine-tuning
- Supports Llama, Qwen, Gemma, DeepSeek
- Custom CUDA kernels under the hood
- Exports GGUF/Safetensors for llama.cpp/vLLM/Ollama
- Runs free on Colab/Kaggle
- Multi-GPU speedups are paid tiers
- NVIDIA-centric, CUDA-focused
- Supports a curated model set
- Requires ML fine-tuning know-how
