MiMo v2.6
Xiaomi’s model got builders talking not only about performance but about unusually transparent training and what 'open' should mean.
Xiaomi released MiMo-V2.6, a new open-weight model family that scored strongly against other open models while offering relatively inexpensive inference.

That led to a deeper argument over what counts as open AI: open weights alone, or weights plus training data, code, methodology and reproducibility.
HN snapshot: about 1.1k points and ~480 comments.
