Model creator: https://huggingface.co/1bitLLM/
Original model: https://huggingface.co/1bitLLM/bitnet_b1_58-large/

Available sizes

| Branch | Bits | Description | | ----- | ---- | ------- | ------ | ------ | ------ | ------ | ------------ | | 8_0 | 8.0 | Maximum quality that ExLlamaV2 can produce, near unquantized performance. | | 6_5 | 6.5 | Very similar to 8.0, good tradeoff of size vs performance, recommended. | | 5_0 | 5.0 | Slightly lower quality vs 6.5, but usable on 8GB cards. | | 4_25 | 4.25 | GPTQ equivalent bits per weight, slightly higher quality. | | 3_5 | 3.5 | Lower quality, only use if you have to. |

Download instructions

With git:

git clone --single-branch --branch 6_5 https://huggingface.co/1bitLLM_-_bitnet_b1_58-large-exl2 bitnet_b1_58-large-6_5

With huggingface hub:

pip3 install huggingface-hub

To download a specific branch, use the --revision parameter. For example, to download the 6.5 bpw branch: Linux:

huggingface-cli download 1bitLLM_-_bitnet_b1_58-large-exl2 --revision 6_5 --local-dir bitnet_b1_58-large-6_5 --local-dir-use-symlinks False

Windows (which apparently doesn't like _ in folders sometimes?):

huggingface-cli download 1bitLLM_-_bitnet_b1_58-large-exl2 --revision 6_5 --local-dir bitnet_b1_58-large-6.5 --local-dir-use-symlinks False

Original model description:

license: mit

This is a reproduction of the BitNet b1.58 paper. The models are trained with RedPajama dataset for 100B tokens. The hypers, as well as two-stage LR and weight decay, are implemented as suggested in their following paper. All models are open-source in the repo. We will train larger models and/or more tokens when resource is available.

Results

PPL and zero-shot accuracy:

The differences between the reported numbers and the reproduced results are possibly variances from the training data processing, seeds, or other random factors.
