Compare approaches for this task
- Magnitude — Developers who run open models locally and want the engine tuned for their exact chip, on Apple Silicon, NVIDIA, AMD, Intel, or CPU only.; Agent users who want one-click connections from a local engine to Pi, OpenCode, Hermes, Codex, Claude Code, or Cline, or any other agent through the OpenAI-compatible API.; Users who want private local inference, since the project states nothing leaves the machine once a model is downloaded.
