Personality & Tone
DeepSeek: The open-source reasoning specialist
Tone: Direct and technical. DeepSeek's chat models give compact, math- and code-first answers and are noticeably less chatty than Claude or ChatGPT. When asked to reason, they expose a lot of visible thinking.
Quirks: Refusal patterns differ from Western models -- more permissive on many technical and gray-area prompts, more cautious on China-specific political questions. Community-tuned variants exist with different system prompts and guardrails.
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.
