How to Use

To utilize Athena-R3-1.5B, ensure that you have the latest version of the transformers library installed:

pip install transformers

Here's an example of how to load the Athena-R3-1.5B model and generate a response:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Spestly/Athena-R3-1.5B"
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Explain the concept of entropy in thermodynamics."
messages = [
    {"role": "system", "content": "You are Athena, an AI assistant designed to be helpful."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

Limitations

Users should be aware of the following limitations:

• Biases: Athena-R3-1.5B may exhibit biases present in its training data. Users should critically assess outputs, especially in sensitive contexts.
• Knowledge Cutoff: The model's knowledge is current up to August 2024. It may not be aware of events or developments occurring after this date.
• Language Support: While the model supports multiple languages, performance is strongest in English.
