What each one is
Nexa SDK
Nexa SDK runs text, vision, audio and image models locally across CPU, GPU and NPU backends, with a single unified API and OpenAI-compatible server.
- Runs on NPUs, not just CPU and GPU
- One API for text, vision and audio models
- OpenAI-compatible local server
GPUStack
GPUStack pools heterogeneous GPUs across machines into one cluster and schedules model workloads across them, with a web UI and OpenAI-compatible endpoints.
- Pools GPUs across many machines
- Mixes NVIDIA, Apple and AMD hardware
- Web UI with usage metrics
Key differences
Nexa SDK is local runtime (SDK), while GPUStack is gPU cluster manager. Nexa SDK leans more intermediate-friendly, whereas GPUStack is more suited to advanced users. In short, Nexa SDK fits developers targeting many device types from one codebase, and GPUStack fits teams with several GPU machines to pool.
Which should you choose?
