NeuralMagic

Neural Magic was an AI software company that spun out of MIT in 2018 to build high-performance deep learning inference software. Its flagship open-source products were DeepSparse, a sparsity-aware inference runtime delivering GPU-class performance on commodity CPUs, together with SparseML, SparseZoo, and Sparsify for model compression, sparsification recipes, and a curated model repository, plus nm-vllm, an enterprise LLM inference server for GPUs. Neural Magic was a prolific contributor to the community vLLM project. The company was acquired by Red Hat (agreement announced November 2024, completed January 2025) and its engineering now advances vLLM and Red Hat AI. The community versions of DeepSparse, SparseML, SparseZoo, and Sparsify were deprecated on 2026-06-02. Neural Magic exposed no commercial REST API; its developer surface was a set of first-party Python libraries published to PyPI and open source on GitHub.

NeuralMagic is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine-Learning, Inference, and LLM.

NeuralMagic’s developer surface includes documentation and 6 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/neuralmagic: open an issue to ask a question, or submit a pull request to add artifacts.
