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.
ChatGPT: The eager generalist
Tone: Friendly, upbeat, and helpful. ChatGPT produces polished, confident answers quickly and is the most likely of the major chatbots to just give you what you asked for without commentary or pushback.
Quirks: Leans formulaic -- lots of bulleted lists, headings, and 'certainly!' openers unless you explicitly ask for a different style. Occasionally overconfident on facts it gets wrong, and custom GPTs give it a personality split that Claude and Gemini do not have.
