Nemotron 3.5 Lightning Free model profile

Evidence snapshot:

Nemotron 3.5 Lightning is a NVIDIA model profile with a 1,000,000-token context window. The dated catalog snapshot records text modalities and interfaces for reasoning controls, text generation, tool calling.

NVIDIA Nemotron 3.5 Lightning is an open mixture-of-experts model from NVIDIA, with 3B active parameters out of 30B total. It is suited for high-throughput agentic workloads and specialized tasks that benefit from domain-specific customization.

Nemotron 3.5 Lightning Free is a reference profile: NVIDIA publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.

Nemotron 3.5 Lightning Free 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 3.5 Lightning Free accepts text and returns text. The snapshot records reasoning controls, text generation, and tool calling as capabilities or interfaces.

No comparable unit price is present in the 2026-09-06 snapshot. A zero placeholder is not presented as a free-price claim.

The 2026-09-06 snapshot includes 1 Artificial Analysis index and AutoExacto results for 4 provider observations. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable.

Nemotron 3.5 Lightning Free ranked #21 in the cited trailing-7-day third-party catalog usage dataset as of 2026-09-06. 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 2026-09-06 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.

When to pick Nemotron 3.5 Lightning Free

Nemotron 3.5 Lightning Free is a reference profile: NVIDIA publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.

Each condition below is derived from this model's own values in the 2026-09-06 snapshot, compared only against models publishing the same field.

  • Reach for it when cost is the binding constraint. At $0 in and $0 out per 1M tokens, combined token price sits in the cheapest quarter of the 146 models publishing both rates in this snapshot.
  • Reach for it when the model has to call tools. Tool calling is recorded in the snapshot, so this route can drive an agent loop rather than only answer in prose.
  • Look elsewhere when you need to call it through Kendr today. This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr.
