Frequently asked questions about Llama 2 13B Chat Hf
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
Llama 2 13B Chat Hf advertises a context window of 4,096 tokens, with a maximum output of 2,048 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 2 13B Chat Hf is an open-weight model released under the Llama2 license, so the weights can be downloaded and self-hosted within that license's terms.
Llama 2 13B Chat 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.
Llama 2 13B Chat Hf 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 Llama 2 13B Chat Hf is shown as not available rather than estimated.
Not on the managed pool today; Llama 2 13B Chat 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 13.1 GB at INT8 for the weights and a default context, from the catalog's 13B 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.
