Run Llama3.1 405B TEXT · Q8_0 on your own GPU

Llama3.1 405B TEXT · Q8_0 is a chat catalog model (405.9B) managed with Ollama. Catalog memory is estimated at 444 GB with Q8_0 for a short context (4–8K tokens). Validate output quality and memory use with your workload on your hardware.

Deploy the catalog Ollama tag on your machine and verify the pulled model's quantization. Once deployed, gpuos serves it as llama3.1-405b-text-q8-0 through the hosted gpuos gateway, with API keys, optional token quotas and usage metering. Request and response payloads pass through that gateway.
