Pros	Access to latest NVIDIA GPUs (Blackwell, Hopper, upcoming Vera Rubin) often ahead of hyperscalers Kubernetes-native with purpose-built AI tooling (Tensorizer, SUNK, Mission Control) Published performance metrics like 96% cluster goodput and MLPerf results Used by OpenAI, Mistral, IBM - proven at frontier-scale 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 self-serve free tier; sales-gated with real capacity commitments Thin non-GPU ecosystem compared to AWS/GCP (no managed DBs, serverless, etc.) Single-vendor NVIDIA story means limited flexibility if you need TPUs or AMD Overkill and expensive for small experiments or single-GPU workloads	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
