Personality & Tone
Hunyuan 3 (Tencent Hy3): Tencent's first serious open-weights LLM
Tone: Direct and structured, similar to DeepSeek's chat tone -- compact answers in technical domains, reasonable Chinese-language polish, English noticeably less expressive than Claude or GPT.
Quirks: PRC content filters apply across the same set of regulated topics as DeepSeek and Qwen. Distribution via Yuanbao + WeChat + QQ means many Hy3 users in the wild are talking to it through chat-app surfaces rather than a developer console.
MiMo (Xiaomi): Xiaomi's voice-first agentic stack
Tone: Direct, multimodal-aware. MiMo-V2.5-Pro is comfortable mixing image, audio, and text inputs in a single turn -- it's been trained for that, not retrofitted to it.
Quirks: Voice-pipeline orientation makes MiMo unusually expressive when audio is in the loop -- TTS variants (VoiceDesign, VoiceClone) and ASR are surfaced as first-class products, which most Chinese frontier vendors haven't done. PRC content filters apply on chat surfaces.
