Best for	—	Teams self-hosting open-weight models ML platform and infra engineers High-throughput production inference
Pros	Drop-in OpenAI-compatible API (plus Anthropic and ElevenLabs compatibility), so existing code often works with just a changed base URL Handles many modalities in one tool: text/chat, embeddings, image generation, speech-to-text and text-to-speech Runs CPU-only with no GPU required, and also accelerates on NVIDIA, AMD, Intel and Apple Silicon Modular backend design pulls engines (llama.cpp, vLLM, whisper.cpp, diffusers) on demand instead of one heavy bundle Permissive MIT license and an active, community-driven project with frequent releases	Completely free and open source (Apache 2.0) Industry-leading throughput via PagedAttention OpenAI-compatible API for easy integration Broad model and quantization support Multi-GPU tensor and pipeline parallelism
Cons	Requires comfort with Docker, model files and YAML configuration; setup is heavier than a prebuilt chat app CPU-only inference can be slow and memory-hungry on larger models, so good speed still benefits from a capable GPU The large number of backends and options means a learning curve to pick the right model and acceleration for your hardware You are responsible for sourcing, storing and updating models, and quality depends entirely on the open models you choose	You must provide and manage GPUs and infrastructure No official managed cloud from the project Rapid release cadence can introduce breaking changes Requires ML systems knowledge to tune and operate No built-in team collaboration or UI
