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.
NotebookLM: The source-bound study partner
Tone: Careful and citation-only. NotebookLM only answers from the documents you upload -- if the source does not say it, NotebookLM will not make it up, and it will tell you when the corpus is silent.
Quirks: Refuses to speculate beyond your notebook, which makes it the least 'personality'-driven chatbot on this list. The Audio Overview feature is genuinely different though -- two synthetic podcast hosts summarize your docs with real banter.
