Tencent is secretly developing a Personal Agent product codenamed 'Handy Bot' and has begun low-profile testing through a WeChat service account. Unlike traditional chatbots that respond to individual queries, Handy Bot is designed to operate persistently in the background, autonomously pursuing user-defined goals. The product is still in internal testing, with plans for a standalone app, as Tencent joins Alibaba and ByteDance in China's emerging Personal Agent category.

Xiaomi identified tool-call repetition as a significant user-experience issue following the MiMo-V2.6 release, with internal evaluations showing response-level repetition rates exceeding 0.05%. After tracing the problem to reinforcement-learning training dynamics where a per-turn flooding penalty threshold proved too permissive, the company adopted Multi-teacher On-Policy Distillation (MOPD), a targeted fix that reduced replay repetition to zero at a training cost of approximately $90,000—about 4% of the estimated MixRL alternative. Updated checkpoints have been available via Xiaomi's API since September 25, and the company announced a quota reset for all MiMo Desktop users.
Chinese AI models now account for 57-67% of tokens on OpenRouter and 55% on Vercel, up sharply from single-digit shares earlier in 2026, driven by cost-effectiveness and improved coding capabilities.
