Key features include zero-cost interoperability with PyTorch, SciPy, and CuPy; a DSL for defining custom sparse formats; polymorphic operations that auto-dispatch to optimized kernels or generate sparse code; and a PyTorch injection mechanism that lets researchers accelerate existing models without rewriting code. Performance benchmarks show speedups of 1.1x to 444x over CuPy and PyTorch for SpMV operations, with additional gains from transparent caching of planning phases. ## Full article daily.dev links to this article rather than hosting it.
