Launch HN: Magnitude (YC S25) – Self-optimizing inference engine for agents

Magnitude is an open-source inference engine that self-optimizes on the target device, promising up to 2x faster open-model execution and lower memory use across Apple Silicon, NVIDIA, AMD, and CPU-only environments. For CIOs and technology leaders, this could reduce the cost and latency of internal AI deployments, improve data privacy by keeping prompts and models on-premises, and give IT teams a more controllable alternative to managed AI runtimes for agentic workflows. Strategically, it increases the viability of running more AI at the edge and on employee devices, but it also shifts responsibility to IT for model distribution, hardware compatibility, benchmarking, and lifecycle management.
