Frequently asked questions about NVIDIA Nemotron 3.5 Lightning 30B A3B
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
NVIDIA Nemotron 3.5 Lightning 30B A3B advertises a context window of 262,144 tokens, with a maximum output of 262,144 tokens in a single response. The figure is the creator's published maximum; a given provider may serve less, and the gateway routes on what each provider actually serves.
Yes. NVIDIA Nemotron 3.5 Lightning 30B A3B is an open-weight model released under the Other license, so the weights can be downloaded and self-hosted within that license's terms.
NVIDIA Nemotron 3.5 Lightning 30B A3B accepts Text and produces Text. The capabilities card on this page lists which API features each deployment honours, such as function calling and structured output, with the source each was checked against.
NVIDIA Nemotron 3.5 Lightning 30B A3B has published results from Artificial Analysis, shown by suite in the benchmarks card above exactly as the publisher reported them. Scores are not combined across suites, and a suite that has not measured NVIDIA Nemotron 3.5 Lightning 30B A3B is shown as not available rather than estimated.
Not on the managed pool today; NVIDIA Nemotron 3.5 Lightning 30B A3B is listed for reference and comparison. Connect your own provider key or endpoint that serves it and the gateway runs it on your account, with routing decisions recorded the same way.
About 30.0 GB at INT8 for the weights and a default context, from the catalog's 30B parameter count; FP16 needs roughly twice that, and long contexts or many concurrent requests add KV cache on top. The GPU section on this page lists cards that hold it, and the capacity planner sizes it for your context length and traffic.
