# LiteLlama: Reduced-Scale Llama |
|
|
|
In this series of repos, we present an open-source reproduction of Meta AI's [LLaMa 2](https://ai.meta.com/llama/). However, with significantly reduced model sizes, [LiteLlama-460M-1T](https://huggingface.co/ahxt/LiteLlama-460M-1T) has 460M parameters trained with 1T tokens. |
|
|
|
|
|
## Dataset and Tokenization |
|
We train our models on part of [RedPajama](https://www.together.xyz/blog/redpajama) dataset. We use the [GPT2Tokenizer](https://huggingface.co/docs/transformers/v4.31.0/en/model_doc/gpt2#transformers.GPT2Tokenizer) to tokenize the text. |
|
|
|
## Training Details |
|
|
|
The model was trained with ~1T tokens (0.98T). num of tokens = steps*length*batch_size=499679*1024*192=98240888832≈0.98T. |
|
|
|
The training curve is at this [WandB project](https://wandb.ai/ahxt/llama2_xs_460M_training_loss/reports/reduced_train_loss-23-09-05-20-25-43---Vmlldzo1MzIwNDUx?accessToken=x2ch3n30jo77p1x8y7q9js4h4d8zpjtz1tzot4xxullyefixp4jwt7au2q37k2q6). |
|
|
|
### Using with HuggingFace Transformers |
|
The experimental checkpoints can be directly loaded by [Transformers](https://huggingface.co/transformers/) library. The following code snippet shows how to load the our experimental model and generate text with it. |
|
|
|
|
|
```python |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
model_path = 'ahxt/LiteLlama-460M-1T' |
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_path) |
|
tokenizer = AutoTokenizer.from_pretrained(model_path) |
|
model.eval() |
|
|
|
prompt = 'Q: What is the largest bird?\nA:' |
|
input_ids = tokenizer(prompt, return_tensors="pt").input_ids |
|
tokens = model.generate(input_ids, max_length=20) |
|
print( tokenizer.decode(tokens[0].tolist(), skip_special_tokens=True) ) |
|
# Q: What is the largest bird?\nA: The largest bird is a black-headed gull. |
|
``` |
|
|
|
## Evaluation |
