Pros
  • Supports any open-source model on Hugging Face Hub
  • LoRA, full fine-tune, RL, and tool-calling in one platform
  • Vision fine-tuning on raw image data (Llama-4, Qwen3-VL)
  • SOC 2 Type II + ISO 27001 with regional data residency
  • Direct deploy to Together's inference stack after training
  • Real, measurable 2-5x speedups and big VRAM savings on consumer GPUs
  • Open-source core with permissive license and active GitHub
  • Drop-in compatible with Hugging Face TRL, PEFT and transformers
  • Excellent ready-to-run Colab notebooks for most popular models
  • Exports cleanly to GGUF/llama.cpp, vLLM and Ollama
Cons
  • No public pricing — cost estimator only after signup
  • Closed-source platform despite open-weight focus
  • Overkill for hobbyists who just want a quick LoRA
  • Multi-GPU and multi-node are gated behind paid tiers with opaque pricing
  • Not a hosted service — you still bring your own GPU and MLOps
  • Cutting-edge model support sometimes lags official releases by days
