Description
Olmo-core 3 is Ai2's open training infrastructure for large mixture-of-experts language models, built as part of the next generation of Olmo. It redesigns MoE training with distributed data parallelism, rowwise expert parallelism, GPU-resident routing, and MXFP8 support. In one benchmark, a 47-billion-parameter MoE reached 52,000 tokens per second per GPU, about 2.7x the throughput of Ai2's earlier FSDP-based implementation. Code and a tech report are on GitHub.

Could you build this?
No This is a cutting-edge distributed ML training framework featuring custom GPU kernels, rowwise expert parallelism, and MXFP8 precision across large clusters.
What it would actually take: Requires deep high-performance computing (HPC) and ML systems expertise in C++/CUDA/PyTorch internals, NCCL communication tuning, GPU-resident routing algorithms, and access to large multi-node GPU clusters (e.g., H100s) for testing.
