AMD's Instella-MoE: an open model that ships with its full training recipe
AMD released Instella-MoE-16B-A3B, a mixture-of-experts model with 16 billion total parameters that activates only 2.8 billion per token, trained end to end on its own Instinct MI300X and MI325X GPUs. Unusually, the release includes checkpoints from every training stage plus the data mixtures, training configs and code — the code under MIT, the weights under a research-only license. AMD says the base model posts the strongest average among fully open models, ahead of Moonlight-16B and OLMo-3.
Why it mattersMost 'open' models ship weights and nothing else. A release that includes the whole training recipe lets researchers actually study and reproduce how a model is built — and it is a working proof that competitive training runs can happen entirely off Nvidia hardware.
