VMware/open-llama-7B-v2-open-instruct (4-bit 128g AWQ Quantized)

Instruction-tuned version of the fully trained Open LLama 7B v2 model. The model is open for COMMERCIAL USE.

This model is a 4-bit 128 group size AWQ quantized model. For more information about AWQ quantization, please click here.

Model Date

July 12, 2023

Model License

Please refer to original OpenLLaMa model license (link).

Please refer to the AWQ quantization license (link).

CUDA Version

This model was successfully tested on CUDA driver v530.30.02 and runtime v11.7 with Python v3.10.11. Please note that AWQ requires NVIDIA GPUs with compute capability of 8.0 or higher.

For Docker users, the nvcr.io/nvidia/pytorch:23.06-py3 image is runtime v12.1 but otherwise the same as the configuration above and has also been verified to work.
