h2oGPT Model Card
Summary
H2O.ai's h2ogpt-oig-oasst1-256-6_9b
is a 6.9 billion parameter instruction-following large language model licensed for commercial use.
- Base model: EleutherAI/pythia-6.9b
- Fine-tuning dataset: h2oai/h2ogpt-oig-oasst1-instruct-cleaned-v1
- Data-prep and fine-tuning code: H2O.ai Github
- Training logs: zip
Usage
To use the model with the transformers
library on a machine with GPUs, first make sure you have the transformers
and accelerate
libraries installed.
pip install transformers==4.28.1
pip install accelerate==0.18.0
import torch
from transformers import pipeline
generate_text = pipeline(model="h2oai/h2ogpt-oig-oasst1-256-6_9b", torch_dtype=torch.bfloat16, trust_remote_code=True, device_map="auto", prompt_type='human_bot')
res = generate_text("Why is drinking water so healthy?", max_new_tokens=100)
print(res[0]["generated_text"])
Alternatively, if you prefer to not use trust_remote_code=True
you can download instruct_pipeline.py,
store it alongside your notebook, and construct the pipeline yourself from the loaded model and tokenizer:
import torch
from h2oai_pipeline import H2OTextGenerationPipeline
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("h2oai/h2ogpt-oig-oasst1-256-6_9b", padding_side="left")
model = AutoModelForCausalLM.from_pretrained("h2oai/h2ogpt-oig-oasst1-256-6_9b", torch_dtype=torch.bfloat16, device_map="auto")
generate_text = H2OTextGenerationPipeline(model=model, tokenizer=tokenizer, prompt_type='human_bot')
res = generate_text("Why is drinking water so healthy?", max_new_tokens=100)
print(res[0]["generated_text"])
