Model Details

Lightning is a small, autoregressive transformer which utilizes FlashAttention and MHA. This model is trained on a variety of books from a dataset(300 MB).

Model Description

Lightning utilizes FlashAttention and AdamW for performance and capability. Lightning is designed to provide quick, coherent outputs, with the downside of limited embedding.

• Developed by: AobanZ
• Model type: Transformer
• Language(s) (NLP): English
• License: MIT
• Finetuned from model [optional]: lightning-30m

Model Sources [optional]

• Repository: https://huggingface.co/Aobangaming/lightning-30m-ft

Uses

Lightning is intended to be used for research, analysis and fine-tuning, stories and other. It is not intended to be used for professional advice, real writing or any kind of heavy work as generated outputs may be incorrect.

Direct Use

Lightning can be used directly for text generation, experimentation, and conversational interactions. Users can provide text prompts and generate responses using the model's built-in language modeling capabilities.

Direct use is primarily intended for research and experimentation. Outputs may be incomplete, inaccurate, repetitive, or unrelated to the input, and should be evaluated before being used for other purposes.

Downstream Use

Lightning may be fined-tuned for an AI Story makers, Research, and small continuation models. However, please note that generated outputs may be corrupted and/or incorrect.

Out-of-Scope Use

Heavy Work may overload the model, which will cause corrupted outputs and/or misinformation if implemented into a larger-app/ecosystem.

Bias, Risks, and Limitations

Lightning is designed to process english text ONLY and cannot be fined-tuned for any other uses(eg. Robotics)

Recommendations

We recommend users of Lightning to finetune the model on new text, and add necessary guardrails and precautions to prevent misuse.

How to Get Started with the Model

Use the code below to get started with the model.

import torch
from transformers import AutoModelForCausalLM
from tokenizers import Tokenizer

model_id = "Aobangaming/lightning-30m-ft"

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    trust_remote_code=True
)

tokenizer = Tokenizer.from_pretrained(model_id)

prompt = "The"

encoded = tokenizer.encode(prompt, add_special_tokens=False)
input_ids = torch.tensor([encoded.ids])

outputs = model.generate(
    input_ids,
    max_new_tokens=100,
    do_sample=True,
    temperature=0.8,
    top_k=40,
    top_p=0.6,
)
print(tokenizer.decode(outputs[0].tolist()))

Training Details

Training Data

Lightning was trained on the full Booksum dataset.

Training Procedure

Lightning was trained on an RTX 3050 GPU, using FlashAttention and MHA. First, the model was initally trained on a large dataset. Then trained on a smaller dataset to fine tune.

Training Hyperparameters
