Free
Magnitude is free, open-source software distributed under the Apache 2.0 license with no token costs, paid editions, or managed service tiers.
Best for
Developers and power users running local coding agents on Apple Silicon or NVIDIA hardware who require high-performance, low-latency inference.
Not ideal for
Users requiring models outside the curated catalog, those using older hardware generations, or platform engineers needing flexible, container-native headless deployments.
Magnitude is an architecturally sophisticated inference engine that justifies its performance claims through real-time kernel compilation, though it currently suits a specific set of supported hardware and model families rather than general-purpose GGUF execution.
The catalog data was updated on 2026-10-14, following the release of engine v3, with a v4 rewrite currently in progress.
