The project has moved into a legacy phase and receives no further updates - Avoid using OptiMate for future AI deployment if you are aiming to integrate state-of-the-art real-time observability features as it's no longer actively maintained nor receiving new improvements ## Common questions ### What is the difference between jax and optimate? jax: Composable transformations of Python+NumPy programs. optimate: A collection of libraries to optimize AI model performances. See the comparison table for live GitHub stats and shared categories. ### When should I choose jax over optimate? Choose jax over optimate when Tags unique to jax: compilation, differentiation, gpu, python; - When you need to perform high-performance numerical computations with support for both forward and reverse mode automatic differentiation on accelerators such as GPUs and TPUs; More GitHub stars (36k vs 8.3k) - visibility, not fit. ### When should I choose optimate over jax?
