With everything going on, it gives me hope that there's such a diversity of companies building open models today.

A lot of the story of open models unfolds under the shadow of the biggest frontier models. Lots of unearthed value.

Another artifact with many new (and recurring!) friends from @NVIDIAAI, @poolsideai, @cohere, @jetbrains and ofc @Zai_org!

An interesting one, given the recent developments. We argue that banning open models is not only unsafe, but ultimately anti-freedom.

And due to our data collection efforts spanning a year at this point, we can make fun graphs like this one!

Turns out that GLM-5.2 is a popular model, but in terms of downloads lags the initial success of something like M2 or Qwen3 MoE.

@natolambert the open model space is diversifying fast

the real story is in specialized models not just the frontier giants

@xeophon I think it's a bit misleading, the chart feels incomplete without 'in terms of downloads', most of people use it much more than any other open-source models ever, most don't bother downloading because they couldn't run it (me)
