Meta's flagship open model — 400B MoE with 128 experts
Verdict
Massive leap for open-source. 400B MoE architecture with 128 experts runs efficiently on 8× H100. Matches frontier closed models on most benchmarks. Best open model for enterprise self-hosting — and now the more relevant Meta model for that use case, since Meta's newer Muse Spark line is closed-weight.
