Xiaomi's open model now rivals Claude and GPT
Xiaomi's MiMo V2.6 Pro reportedly matches Claude Opus 5 and GPT-5.6 on many agent and coding benchmarks as a fully open-weight model trained for roughly $3M — another data point that frontier-class capability keeps getting cheaper to reproduce outside the labs that pioneered it. For cost-sensitive projects like the ones at DotTif Labs, that's one more open-weight option worth pricing against whatever's currently running in production.
What’s Mixture-of-Experts (MoE) activated parameters?
MoE builds a model from many specialized sub-networks ('experts'), where a router picks only a handful to process each token instead of running the whole network every time.
That decouples total capacity from per-token compute cost: a 1-trillion-parameter model can cost roughly what a 42-billion-parameter dense model costs to run, because only ~42B parameters activate per token — hence '1T-A42B'.
MoE used to be a research curiosity; it's now how most frontier-scale open-weight models (DeepSeek, MiMo, and others) reach huge parameter counts without a proportionally huge inference bill.
The tradeoff is that MoE models are cheaper to run but harder to train stably and serve efficiently across GPUs, since routing varies token to token — which is part of why closed labs have moved more cautiously into it at the largest scales.
