# TinyLlama-1.1B |
|
</div> |
|

https://github.com/jzhang38/TinyLlama |
|
|
|
The TinyLlama project aims to **pretrain** a **1.1B Llama model on 3 trillion tokens**. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs 🚀🚀. The training has started on 2023-09-01. |
|
|
|
|
|
We adopted exactly the same architecture and tokenizer as Llama 2. This means TinyLlama can be plugged and played in many open-source projects built upon Llama. Besides, TinyLlama is compact with only 1.1B parameters. This compactness allows it to cater to a multitude of applications demanding a restricted computation and memory footprint. |

|
#### This Model |
|
This is the chat model finetuned on top of [TinyLlama/TinyLlama-1.1B-intermediate-step-955k-2T](https://huggingface.co/TinyLlama/TinyLlama-1.1B-intermediate-step-955k-token-2T). **We follow [HF's Zephyr](https://huggingface.co/HuggingFaceH4/zephyr-7b-alpha/edit/main/README.md)'s training recipe.** The model was " initially fine-tuned on a variant of the [`UltraChat`](https://huggingface.co/datasets/stingning/ultrachat) dataset, which contains a diverse range of synthetic dialogues generated by ChatGPT. |
|
We then further aligned the model with [🤗 TRL's](https://github.com/huggingface/trl) `DPOTrainer` on the [openbmb/UltraFeedback](https://huggingface.co/datasets/openbmb/UltraFeedback) dataset, which contain 64k prompts and model completions that are ranked by GPT-4." |

|
#### How to use |
|
You will need the transformers>=4.34 |
|
Do check the [TinyLlama](https://github.com/jzhang38/TinyLlama) github page for more information. |
|
|
|
```python |
|
# Install transformers from source - only needed for versions <= v4.34 |
|
# pip install git+https://github.com/huggingface/transformers.git |
|
# pip install accelerate |
|
|
|
import torch |
|
from transformers import pipeline |
|
|
|
pipe = pipeline("text-generation", model="TinyLlama/TinyLlama-1.1B-Chat-v0.6", torch_dtype=torch.bfloat16, device_map="auto") |
|
|
|
# We use the tokenizer's chat template to format each message - see https://huggingface.co/docs/transformers/main/en/chat_templating |
|
messages = [ |
|
{ |
|
"role": "system", |
|
"content": "You are a friendly chatbot who always responds in the style of a pirate", |
|
}, |
|
{"role": "user", "content": "How many helicopters can a human eat in one sitting?"}, |
|
] |
|
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True) |
|
outputs = pipe(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95) |
|
print(outputs[0]["generated_text"]) |
|
# <|system|> |
|
# You are a friendly chatbot who always responds in the style of a pirate.</s> |
|
# <|user|> |
|
# How many helicopters can a human eat in one sitting?</s> |
|
# <|assistant|> |

# ... |
