- 2026-09-23-AI-Digest — The Decoder’s Sept 22 write-up surfaces Anthropic case
GTG-16008: Anthropic alleges Xiaomi improperly funnelled~400Kuser exchanges through OpenClaw/OpenCode to Claude in March–April 2026 to distil training data for MiMo v2.6 (referred to as MiMo-V2.6-Pro). Load-bearing framing to carry: The Decoder’s headline “Claude helped get it there” is Anthropic’s acknowledgment of unauthorised distillation, not a commercial arrangement — the framing reads as validation but is legal/IP overhang. Xiaomi is the seventh Chinese lab named in the pattern the FBI/NSA/CISA sequence has been tracking through DeepSeek, Moonshot, MiniMax, Alibaba, StepFun, and Z.AI. MiMo-V2.6-Pro currently sits at46on the Artificial Analysis open-weights composite.

GTG-16008alleges~400Kuser exchanges from Xiaomi through OpenClaw/OpenCode were used to distil training data for MiMo-V2.6-Pro in March–April 2026. First direct linkage between the seven-Chinese-labs distillation pattern and a specific MiMo release. Corpus framing: legal overhang, not commercial validation — do NOT lift The Decoder’s “Claude helped get it there” as endorsement. MiMo-V2.6-Pro at #46 on the Artificial Analysis open-weights composite. Watch clause: whether Anthropic’s civil action progresses beyond the technical accusation.
