Baidu: ERNIE 4.5 21B A3B ThinkingModel25/100 via “scientific-explanation-and-knowledge-synthesis”
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: Trained on curated scientific corpora and peer-reviewed abstracts with domain-specific token embeddings for scientific terminology, enabling the model to maintain semantic precision across scientific domains while generating multi-level explanations through conditional generation based on audience context.
vs others: Produces more scientifically accurate explanations than GPT-3.5 on domain-specific benchmarks while being more accessible than specialized domain models; trades some accuracy for generality compared to domain-specific fine-tuned models
