Anthropic's Opus 5.5 drop today pushed the entire intelligence frontier from 46.3 up, displacing GPT-6 Astra and Anthropic's own Fable 5.1. Excited to see what this new model can do!
GLM-5.3-Flash is now the cheapest way to reach Artificial Analysis Intelligence Index 52.3 to 57.5, at 8.7¢ per task. It also has open weights. It displaces Muse Spark 1.2, Grok 4.5, Gemini 3.7 Flash, and DeepSeek V4 Pro from the Pareto frontier.

Introducing zarr-matlab 🎉
Zarr v3, natively in MATLAB. A free, open-source, pure-MATLAB implementation of the Zarr spec — chunked, compressed, cloud-friendly N-D arrays, tested for interop with zarr-python on every commit.

Once a year our whole distributed team gets together for a retreat. This spring it was a villa in the hills above Nice. A week of team-led talks, a sunset boat tour, and late-night conversations that wandered from spike sorting to philosophy.

We gave a tutorial on @NeurodataWB and DANDI at @CosyneMeeting this year. If you couldn't make it (or want a refresher), the recording covers everything from data standardization to finding and reusing public neurophysiology datasets on DANDI.
