Pros	One API, thousands of models Easy fine-tuning of Llama, SD, Flux Strong community Predictable per-second pricing	PagedAttention delivers industry-leading throughput on the same hardware Drop-in OpenAI-compatible API makes migration from hosted models trivial Broad hardware support spanning NVIDIA, AMD, Intel, TPU, and Neuron Apache-2.0, no per-token cost, no vendor lock-in Backed by Berkeley + major-cloud sponsors with very active release cadence
Cons	Per-second pricing can surprise Hosted models vary in quality	You provide and operate the GPUs; no managed offering Steep learning curve for tuning parallelism, quantization, and KV cache Bleeding-edge model support sometimes lags the model's release by days Multi-node deployment requires Ray or Kubernetes plumbing
