Frequently asked questions about Llama 3.1 Nemotron 70B Instruct HF
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
Llama 3.1 Nemotron 70B Instruct HF advertises a context window of 131,072 tokens, with a maximum output of 4,096 tokens in a single response. The figure is the creator's published maximum; a given host may serve less, and the gateway routes on what each host actually serves.
Yes. Llama 3.1 Nemotron 70B Instruct HF is an open-weight model released under the Llama3.1 license, so the weights can be downloaded and self-hosted within that license's terms.
Llama 3.1 Nemotron 70B Instruct HF 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.
No published benchmark result for Llama 3.1 Nemotron 70B Instruct HF is in the catalog yet, so the model is shown as unmeasured. It is not ranked or estimated; the router treats it as unknown for every task until a suite measures it.
Not on the managed pool today; Llama 3.1 Nemotron 70B Instruct HF 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 69.0 GB at INT8 for the weights and a default context, from the catalog's 70.6B 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.
