🎉 Exciting news! Python-Blosc2 is making huge strides towards array-api compliance. 🚀
From its humble beginnings in 2010 as a compressor for PyTables, it has evolved into a powerful n-dimensional container. 💪
There's more to come, but what a fantastic milestone! ✨

A step closer to compliance with the array-api standard: data-apis.org/array-api!
This is an effort across all array-based libraries so that your code works (e.g. for both blosc2 and NumPy) by simply changing the import statement below!

LLMs are getting quite good at producing code. But when that last drop of performance counts, it seems our carbon-based predecessors 🧠, armed with good tools and a healthy obsession, still have a few tricks up their sleeves.
Struggling to get performant code from LLMs? 🤔
We can help! 💪 We've spent countless hours profiling and micro-benchmarking Blosc2 for you. A thing that LLMs cannot do (yet).
