ernie-4.5-21b-a3bThis is a text-based Mixture-of-Experts (MoE) model with 21B total parameters and 3B active per token, designed for efficient, high-quality generation and understanding. It supports a long 131K-token context window and achieves fast inference through parallel expert routing and quantization. Advanced post-training methods (SFT, DPO, UPO) and specialized routing/balancing techniques optimize performance across diverse tasks.
