Best for
  • Teams self-hosting open-weight models
  • ML platform and infra engineers
  • High-throughput production inference
  • Developers wanting local, private LLMs
  • Privacy-conscious teams
  • Offline and on-device use cases
Pros
  • 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
  • Free and open source
  • Extremely simple to install and use
  • Runs fully offline with no per-token fees

  • Cross-platform (macOS, Windows, Linux)
Cons
  • 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
  • Performance bounded by local hardware
  • Largest frontier models need the paid cloud
  • No built-in team collaboration features
  • Quality depends on chosen model and quantization
  • Local setup still requires adequate RAM and GPU
