 Benchmarks and evaluation for model meta-llama/Meta-Llama-3.1-8B are run on a machine with a single NVIDIA-H100 GPU using the scripts for [generation](../_models/llama/generate.py) and [eval](../_models/llama/eval.py). Evaluation was done using the lm_eval library for tasks/data.

 note: Int8 dynamic quantization works best on compute bound models like [SAM](https://github.com/pytorch-labs/segment-anything-fast) whereas Llama with batchsize=1 tends to be memory bound, thus the rather low performance.
 
 For int4 we make heavy use of [tinygemm](https://github.com/pytorch/ao/blob/cb3bd8c674f2123af232a0231b5e38ddafa756a8/torchao/dtypes/aqt.py#L526) of `torch.ops.aten._weight_int4pack_mm` to bitpack into a layout optimized for tensor cores
