Magnitude instead treats the hardware as part of the problem: it compiles and tunes its kernels on the device where it runs, so the same open model is served with code shaped to that specific CPU or GPU. The maker's benchmark puts the result at up to 2x the throughput of llama.cpp, with coverage spanning Apple Silicon, NVIDIA, AMD, and plain CPU. For an agent that makes many model calls, more tokens-per-second on owned hardware is the difference between a snappy loop and a slow one — and because it is self-hosted and Apache-2.0, the engine, the models, and the tuning all stay on infrastructure you control.

Magnitude's bet is that device-specific kernel compilation beats generic binaries — and if the 2x-over-llama.cpp claim holds on your box, that is real money and latency back on every agent step, with nothing leaving your infrastructure. For a GTM team self-hosting models behind prospecting, enrichment, or support agents, it is worth a head-to-head. The honest read: the speedup is a vendor benchmark and will vary with your model, quantization, and chip, and on-device tuning adds a first-run cost — so measure it against your current stack before you commit, rather than taking the 2x at face value."
