Baidu: ERNIE 4.5 21B A3B ThinkingModel25/100 via “expert-level-question-answering-across-domains”
ERNIE-4.5-21B-A3B-Thinking is Baidu's upgraded lightweight MoE model, refined to boost reasoning depth and quality for top-tier performance in logical puzzles, math, science, coding, text generation, and expert-level academic benchmarks.
Unique: Combines broad-domain training with A3B reasoning to dynamically allocate compute toward domain-specific reasoning paths, enabling expert-level depth across diverse domains without requiring separate specialized models. Uses uncertainty quantification in reasoning chains to flag areas of lower confidence.
vs others: Provides more nuanced, multi-perspective answers than GPT-3.5 while being more efficient than GPT-4; trades some depth in highly specialized domains for broader expert-level coverage across domains
