Marin‑8B models debut as the first fully open JAX‑trained foundation models
Stanford’s CRFM released Marin‑8B‑Base and Marin‑8B‑Instruct, the first fully open‑source foundation models built with JAX, and shipped every artifact—code, dataset, hyperparameters, training logs—under Apache 2.0. This end‑to‑end transparency lets researchers reproduce, audit, and extend large‑scale models without opaque black‑boxes, raising the baseline for openness in AI.
