It's surprising how often the powerful SIMD capabilities of modern processors are overlooked. Harnessing them is key to unlocking next-level performance.

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).

🚀 We're thrilled to announce *TreeStore*, a new class in Python-Blosc2! Endow your datasets with a hierarchical structure! ⚡️

📝 We've blogged about it:
www.blosc.org/posts/new-tr...

It's in beta, and available in Python-Blosc2 v3.7.2. Enjoy!

📣 #Caterva2 2025.8.7 is out! 🚀

We did a major refactoring for a simpler, more robust system, with client APIs unaffected. ✅

The highlight is the new cat2agent 🤖, a CLI client to watch a directory and auto-sync it with a Caterva2 server.

Happy to sponsor such an excellent work!

📢 We are happy to announce the release of Python-Blosc2 3.2.0!

This release introduces the new blosc2.matmul() function. We have written a nice blog: www.blosc.org/posts/optimi...

Lastly, we are excited to introduce WASM32 wheels for the first time. More info at: github.com/Blosc/python...

Enjoy!

Happy to be sponsoring such an extremely useful project! Cheers! 🥂

Happy to sponsor this fine work.

Difference in perception when using blosc2+grok for a 2x better compression ratio.

@Blosc2 makes compression even better for tomography in synchrotron facilities in Europe by allowing up to 2x better compression ratio, helping already good codecs to shine even more, without almost no loose in perceived quality.

Read our paper on how we achieved this:
blosc.org/docs/LEAPS-I...

Happy to see this multi-year effort out of its cage! Best of luck!
