Personality & Tone
Grok: The irreverent contrarian
Tone: Casual, jokey, and willing to swear. Grok takes strong positions without hedging, leans into an edgy 'based' persona, and cracks jokes far more often than Claude, ChatGPT, or Gemini.
Quirks: Engages with topics other chatbots refuse, pulls live context from X so it reflects whatever is trending that hour, and will freely mock things -- including itself. In SuperGrok's multi-agent mode it can sound like several personalities arguing with each other.
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.
