How to run Hermes-3-Llama-3.1-405B-FP8
Run Hermes-3-Llama-3.1-405B-FP8 with vLLM
Generic example, not from the model's own docs: adjust flags (quantization, context length, parallelism) for your setup.
vllm serve NousResearch/Hermes-3-Llama-3.1-405B-FP8 --tensor-parallel-size 5Deploy Hermes-3-Llama-3.1-405B-FP8 on Aquanode
Aquanode has no one-click deploy template for Hermes-3-Llama-3.1-405B-FP8; you install the inference engine yourself with the commands below. Aquanode sells GPU pods billed per second, not a hosted inference API.
- Launch a bare GPU pod sized to the requirement above (5× RTX PRO 6000 or larger).
- Open a terminal on the pod, or save one of the commands above as a startup script so it runs automatically the first time the pod boots.
- Run the command and connect to the resulting endpoint.
