NVIDIA: Nemotron 3.5 Lightning (free)
nvidia/nemotron-3.5-lightning:freeAbout this API
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...
Provider-supplied description, not an independently validated performance claim.These are the catalogue’s token tariffs. Image, audio, video, search and other charges may use different billing units. Zero token rates alone do not mean those services are free. See the complete pricing fields below and the source model page.
- Published input token pricing is at or below the median of catalogue entries with the same output modalities and known tariffs.
- Published output token pricing is at or below the same-modality catalogue median.
- The published 1,000,000-token context window can accommodate larger inputs, subject to gateway limits.
- No separate per-request fee is listed in this catalogue observation. Other modality charges may apply.
- The upstream catalogue advertises tool-call parameters. This gateway does not expose them yet.
- Trident Protocol currently limits requests to text content, 24 KB of conversation and at most 4,096 output tokens. Free variants remain subject to upstream rate limits and availability.
- No independent latency, uptime, reasoning-quality or coding benchmark has been measured by this application.
Assessment uses published fields and unweighted price medians across 426 entries with the same output modalities and known tariffs. It is a cost-and-capability comparison, not a quality ranking or recommendation.

One catalogue observation per hour. History begins when this deployment first observes the model. No backfilled or interpolated prices.
Zero baseline. Published token tariffs, not total multimodal cost or performance scores.
