stablelm-tuned-alpha-7b-sharded-8bit

This is a sharded checkpoint (with ~4GB shards) of the stabilityai/stablelm-tuned-alpha-7b model in 8bit precision using bitsandbytes .

Refer to the original model for all details w.r.t. to the model. For more info on loading 8bit models, refer to the example repo and/or the 4.28.0 release info .

• total model size is only ~7 GB!
• this enables low-RAM loading, i.e. Colab :)

Basic Usage

You can use this model as a drop-in replacement in the notebook for the standard sharded models.

Python

Install/upgrade transformers , accelerate , and bitsandbytes . For this to work you must have transformers>=4.28.0 and bitsandbytes>0.37.2 .

pip install -U -q transformers bitsandbytes accelerate

Load the model. As it is serialized in 8bit you don't need to do anything special:

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "ethzanalytics/stablelm-tuned-alpha-7b-sharded-8bit"
tokenizer = AutoTokenizer.from_pretrained(model_name)

model = AutoModelForCausalLM.from_pretrained(model_name)
