Nemotron 3 Ultra model profile
Evidence snapshot:
Nemotron 3 Ultra is a NVIDIA model profile with a 512,288-token context window. The dated catalog snapshot records text modalities and interfaces for prompt caching, reasoning controls, structured output, text generation, tool calling.
Nemotron 3 Ultra is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.
Nemotron 3 Ultra accepts text and returns text. The snapshot records prompt caching, reasoning controls, structured output, text generation, and tool calling as capabilities or interfaces.
The dated reference snapshot lists $0.6 input and $3.6 output per million tokens. Cached input is $0.2 per million tokens.
The 2026-08-12 snapshot includes 3 Artificial Analysis indexes and 8 Design Arena categories. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable.
Nemotron 3 Ultra ranked #66 in the cited trailing-7-day third-party catalog usage dataset as of 2026-08-12. Observed within the cited trailing-7-day third-party catalog usage dataset; this is not global AI market share.
Profile data was reviewed for the 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.
