Pros	Substantially cheaper H100/A100/B200 hours than AWS, GCP or Azure Per-minute billing with no egress fees Pre-installed Lambda Stack means instances are training-ready in minutes Offers both single on-demand GPUs and full multi-thousand-GPU clusters SOC 2 Type II with single-tenant hardware isolation on clusters	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	Popular GPUs (H100, B200) are frequently sold out No managed fine-tuning-as-a-service API - you run your own training stack Fewer managed services and regions than AWS/GCP/Azure	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
