Ai2 released Olmo-core 3, an open training framework for large mixture-of-experts models. The company reports about 2.7× the throughput of its earlier FSDP-based implementation and benchmarks up to 1.2 trillion total parameters on 512 NVIDIA B300 GPUs. It is the infrastructure for Ai2's next MoE-based Olmo, not a model release.
