Xiaomi's MiMo-V2.6 arrived as open weights
Xiaomi introduced the MiMo-V2.6 series on 22 September, publishing the Pro variant under open weights; coverage at the time positioned it as the strongest open-weight model available. That last claim is a third-party judgement we have not tested, but the release itself is verifiable from the vendor's own page.
Every strong open-weight release lowers the floor for what you should expect from money spent on a closed model. It is also why "can I run this locally" moved from a privacy curiosity to a cost question — the honest answer on our local-model profiles is that the software is free and the hardware and the upkeep are not.
