Recommended environment variables. KV_CACHE quantization “q4_0” in particular RECOMMENDED, unless “q8_0” is needed (eg. by Qwen-2_5-VL-7B-Instruct-virtuoso, etc).

export OLLAMA_NUM_THREADS=18
export OLLAMA_FLASH_ATTENTION=1
export OLLAMA_KV_CACHE_TYPE="q4_0"
export OLLAMA_NEW_ENGINE=true
export OLLAMA_NOHISTORY=true
export OLLAMA_NUM_PARALLEL=1
export OLLAMA_MAX_LOADED_MODELS=1

Adjust OLLAMA_NUM_THREADS and/or disable HyperThreading, etc, to prevent crippling performance loss.

CAUTION - Preservation

Pulling the model this way relies on the ollama repository, and more generally, reliability of internet services, which has been rather significantly fragile.

If possible, you should use the “Llama-3-virtuoso” project, which automatically caches an automatically installable backup copy.
