Architecture, strengths and use cases

NVIDIA Nemotron 3 Super 120B-A12B is an official self-hostable NVIDIA release in the NVIDIA Nemotron General track. It uses NemotronHForCausalLM, carries 120B / 12B MoE, supports a verified context window of 262,144 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.

NVIDIA Nemotron 3 Super 120B-A12B uses NemotronHForCausalLM with 120B / 12B MoE. The stored architecture profile records 88 layers, hidden width 4096, 32 attention heads and a 262,144 token context ceiling where the official configuration publishes those fields.

License and self-hosting considerations

The full 120B resident weight set must fit across the selected GPUs. Context and concurrency add KV-cache memory; MoE active parameters do not replace resident-weight memory.
