Current Main Summary
- Nemotron is a hybrid family: attention, Mamba, MoE, MTP, and VL all intersect.
- Because of that, graph execution, cache dtype, and quantized MoE correctness are the primary risk areas.
Key Landed PRs
- #16172
NemotronH PP support: Opened pipeline parallelism on NemotronH. - #16227
Add latent MoE support: Added the hybrid latent-MoE path. - #19903
Enable Piecewise CUDA Graph for NemotronH Hybrid Models: Improved hybrid serving efficiency. - #20407
Support Nemotron 3 Super NVFP4: Added the key quantized Super checkpoint path. - #20575
Add Nemotron 3 Super CI tests for BF16 and NVFP4: Added regression coverage for the production checkpoint variants.
Validation Lanes
- Startup on the cookbook checkpoint or example route.
- Re-run the parser, quantization, or multimodal lane that matches this family.
- Re-check registered or manual tests after touching loader or processor code.

Run an autonomous Humanize-governed vLLM SOTA performance loop for one LLM model: first perform the fixed fair vLLM/SGLang/TensorRT-LLM deployment search and benchmark, then start one RLCR loop that repeatedly decides the gap, profiles the current bottleneck, runs layer/kernel pipeline analysis, patches vLLM code, optionally uses ncu-report-skill for kernel evidence, and revalidates until vLLM matches or beats the best observed framework under the same workload and SLA.
