+# Model Card
+## Summary
+
+h2o-danube2-1.8b-sft is a chat fine-tuned model by H2O.ai with 1.8 billion parameters. We release three versions of this model:
+
+| Model Name                                                                         |  Description    |
+|:-----------------------------------------------------------------------------------|:----------------|
+|  [h2oai/h2o-danube2-1.8b-base](https://huggingface.co/h2oai/h2o-danube2-1.8b-base) | Base model      |
+|  [h2oai/h2o-danube2-1.8b-sft](https://huggingface.co/h2oai/h2o-danube2-1.8b-sft)   | SFT tuned       |
+|  [h2oai/h2o-danube2-1.8b-chat](https://huggingface.co/h2oai/h2o-danube2-1.8b-chat) | SFT + DPO tuned |
+
+This model was trained using [H2O LLM Studio](https://github.com/h2oai/h2o-llmstudio).
+
+## Model Architecture
+
+We adjust the Llama 2 architecture for a total of around 1.8b parameters. For details, please refer to our [Technical Report](https://arxiv.org/abs/2401.16818). 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:
+
+| Hyperparameter  |  Value |
+|:----------------|:-------|
+|    n_layers     |     24 |
+|     n_heads     |     32 |
+|  n_query_groups |      8 |
+|     n_embd      |   2560 |
+|   vocab size    |  32000 |
+| sequence length |   8192 |
+
+## Usage
+
+To use the model with the `transformers` library on a machine with GPUs, first make sure you have the `transformers` library installed.
+
+```bash
+pip install transformers>=4.39.3
+```
+
+```python
+import torch
+from transformers import pipeline
+
+pipe = pipeline(
+    "text-generation",
+    model="h2oai/h2o-danube2-1.8b-sft",
+    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,
+    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|>
+```
+
+## Quantization and sharding
+
+You can load the models using quantization by specifying ```load_in_8bit=True``` or ```load_in_4bit=True```. Also, sharding on multiple GPUs is possible by setting ```device_map=auto```.
+
+## Model Architecture
