- One-click integration with popular coding agents
- Support for Apple Silicon, NVIDIA, AMD, and CPU inference

## Pricing

**Model**: Free

Magnitude is free, open-source software distributed under the Apache 2.0 license with no token costs, paid editions, or managed service tiers.

## Who it is for

- **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.

## Verdict

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.

## Recent updates

The catalog data was updated on 2026-10-14, following the release of engine v3, with a v4 rewrite currently in progress.
