Minueza-32M-Base

Summary

Minueza-32M-Base is a foundation model with 32 million parameters trained from scratch on a large corpus of text in English.

It's available in the following formats: Safetensors, GGUF, and ONNX.

And it's being released alongside some fine-tuned versions:

• Minueza-32M-UltraChat: Trained on a single conversational dataset.
• Minueza-32M-Chat: Trained on a mix of conversational datasets.
• Minueza-32Mx2-Chat: Sparse Mixture of Experts trained on interleaved conversational datasets.
• And more...

Intended Uses

This model was created with the following objectives in mind:

• Run on mobile web browsers via Transformers.js.
• Run fast on machines without GPU.
• Serve as a base for fine-tunes using ChatML format, hence the two additional special tokens (<|im_start|> and <|im_end|>) with <|im_end|> as default EOS token.
  • ChatML works great for both instruction and chat models, so if all fine-tunes are made following the ChatML pattern, other users might benefit from the easiness of creating merges.

Datasets

The model was trained on a subset of each of the following non-synthetic datasets:

• Skylion007/openwebtext
• c4
• wikimedia/wikipedia - 20231101.simple
• tiiuae/falcon-refinedweb
• izumi-lab/open-text-books
• togethercomputer/RedPajama-Data-V2
• databricks/databricks-dolly-15k
• euclaise/reddit-instruct-curated
• CohereForAI/aya_dataset - original english annotations

The subsets were interleaved to form the final training corpus of approximately 650 million tokens.

Usage

This is just a base model. For your task, you will likely want to perform application-specific fine-tuning as recommended above.

Also note that this model was trained on internet text data, which may contain biases, offensive or inappropriate content, and may produce incorrect or irrelevant responses. No evaluation has been conducted, so use with care.

Having that said, here's how you can run it:

from transformers import pipeline

generate = pipeline("text-generation", "Felladrin/Minueza-32M-Base")

prompt = "The best way to improve your health is"

output = generate(
    prompt,
    max_new_tokens=256,
    do_sample=True,
    temperature=0.72,
    top_p=0.73,
    top_k=50,
    repetition_penalty=1.176,
)

print(output[0]["generated_text"])
