đ h2o-danube3-500m-chat
h2o-danube3-500m-chat is a chat fine - tuned model by H2O.ai with 500 million parameters, offering base and chat versions. It can run natively and offline on phones.

đ Quick Start
h2o-danube3-500m-chat is a chat fine - tuned model by H2O.ai with 500 million parameters. We release two versions of this model:
Model Name | Description |
---|---|
h2oai/h2o-danube3-500m-base | Base model |
h2oai/h2o-danube3-500m-chat | Chat model |
This model was trained using H2O LLM Studio.
Can be run natively and fully offline on phones - try it yourself with H2O AI Personal GPT.
⨠Features
- Fine - tuned for Chat: Specifically designed for chat scenarios.
- Multiple Versions: Offers base and chat versions to meet different needs.
- Offline Capability: Can run natively and fully offline on phones.
đĻ Installation
To use the model with the transformers
library on a machine with GPUs, first make sure you have the transformers
library installed.
pip install transformers>=4.42.3
đģ Usage Examples
Basic Usage
import torch
from transformers import pipeline
pipe = pipeline(
"text-generation",
model="h2oai/h2o-danube3-500m-chat",
torch_dtype=torch.bfloat16,
device_map="auto",
)
# We use the HF Tokenizer chat template to format each message
# https://huggingface.co/docs/transformers/main/en/chat_templating
messages = [
{"role": "user", "content": "Why is drinking water so healthy?"},
]
prompt = pipe.tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
res = pipe(
prompt,
return_full_text=False,
max_new_tokens=256,
)
print(res[0]["generated_text"])
This will apply and run the correct prompt format out of the box:
<|prompt|>Why is drinking water so healthy?</s><|answer|>
Advanced Usage
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "h2oai/h2o-danube3-500m-chat"
tokenizer = AutoTokenizer.from_pretrained(
model_name,
)
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype=torch.bfloat16,
device_map="auto",
trust_remote_code=True,
)
messages = [
{"role": "user", "content": "Why is drinking water so healthy?"},
]
prompt = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
inputs = tokenizer(
prompt, return_tensors="pt", add_special_tokens=False
).to("cuda")
# generate configuration can be modified to your needs
tokens = model.generate(
input_ids=inputs["input_ids"],
attention_mask=inputs["attention_mask"],
min_new_tokens=2,
max_new_tokens=256,
)[0]
tokens = tokens[inputs["input_ids"].shape[1]:]
answer = tokenizer.decode(tokens, skip_special_tokens=True)
print(answer)
đ§ Technical Details
We adjust the Llama 2 architecture for a total of around 500m parameters. For details, please refer to our Technical Report. We use the Mistral tokenizer with a vocabulary size of 32,000 and train our model up to a context length of 8,192.
The details of the model architecture are:
