We have released v0.13 of nx, exla and torchx, along with a recently released emlx v0.4.
Nx
This is where the bulk of the updates happened!
hooks and tokens are now soft-deprecated (hard-deprecated in nx main). We have introduced `Nx.io_call` as a “side-effect only” sister function to `Nx.runtime_call`, both of which allow inlining generic Elixir code. API for Nx.io_call is generally very similar to hooks+tokens, but requires less plumbing under the hood for compilers.
Nx (along EXLA and Torchx as examples) now includes a backend documentation standardization guide, which helps library users to find specific quirks of functions in each backend. See EXLA’s docs for an example.

EMLX
v0.4 introduces a native compiler with massive performance improvements!
The new compiled mode supports all of the Nx API surface (including defn while loops), and current main branch now also introduces a plugin system which will be released very soon in v0.5.
For example, on my machine Qwen3 0.6B-4bit executes on speeds similar to what ollama provides, which is a great indicator of performance.
