Instella MoE 16B A3B Base
Instella-MoE-16B-A3B-Base is the long-context checkpoint AMD designates as the final base model in its Instella-MoE family, a fully open Mixture-of-Experts language model with 16 billion total parameters and 2.8 billion active parameters per token. It extends the mid-trained checkpoint with long-context training so it can process and reason over longer sequences, and serves as the foundation for the SFT, DPO, and RL post-trained checkpoints.
