| Nemotron 3 Ultra self-hostable 1M-context reasoning | 8.5 | GA | 2026-06-03 | — / — | 1M | Review → |
Nemotron 3 Ultra is NVIDIA's frontier-adjacent open-weights flagship: a 550B-parameter hybrid MoE (55B active) released 2026-06-04 under the permissive OpenMDW-1.1 license, with a full 1M-token context and — unusually for mid-2026 — benchmarks you can actually reproduce, because the weights are public. It posts strong, verifiable coding and reasoning numbers (SWE-bench Verified 70.7, LiveCodeBench 89.0, MMLU-Pro 86.8) and a class-leading long-context result (RULER 94.7 at 1M tokens). It is text-only and multi-node to serve, but arriving just as Meta closed its open frontier line, it makes NVIDIA the credible Western open-weights anchor — and every self-hosted copy runs best on NVIDIA silicon.
