Install dependencies

bash

pip install transformers
# Omit `flash-attn` if not supported by your hardware
pip install flash-attn --no-build-isolation

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto

# INITIALIZE the model and the tokenizer
model = AutoModelForCausalLM.from_pretrained(
    "pints-ai/1.5-Pints-2k-v0.1",
    device_map=device,
    attn_implementation="flash_attention_2" # can be omitted if not supported
)
tokenizer = AutoTokenizer.from_pretrained("pints-ai/1.5-Pints-2k-v0.1")

# PREPARE and tokenize the prompt
prompt = "Predict what life will be like 100 years from now."
messages = [
    {"role": "system", "content": "You are an AI assistant that follows instruction extremely well. Help as much as you can."},
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

input = tokenizer([text], return_tensors="pt").to(device)

# GENERATE the response
generated_ids = model.generate(
    input.input_ids,
    max_new_tokens=512
)

# DECODE the response
input_length = len(input.input_ids[0])
# Remove the input and decode only the output
response = tokenizer.decode(generated_ids[0][input_length:])

print(response)

Compute Infrastructure
This model can be served with a GPU containing at least 8GB of VRAM.

Description

1.5 Pints is a Large Language Model that significantly advances the efficiency of LLM training by emphasizing data quality over quantity. Our pre-training corpus is a meticulously curated dataset of 57 billion tokens, thus making pre-training more accessible and environmentally-friendly.

Results

MTBench
MTBench is a popular evaluation harness that uses strong LLMs like GPT-4 to act as judges and assess the quality of the models' responses.

Technical Specifications

Architecture
Llama 2 Autoregressive Model with 2K Context Window and Mistral tokenizer. The model uses Float32 precision.

Parameters	Vocab Size	Embedding Size	Context Length	Layers	Heads	Query Groups	Intermediate Hidden Size
1,565,886,464	32,064	2,048	2,048	24	32	4	8,192

Context Lengths
1.5-Pints comes in 2 context lengths - 16k (16,384) and 2k (2,048).

Prompt template
This model has been finetuned and preference-optimized using the ChatML template.

<|im_start|>system 
{SYSTEM_PROMPT}<|im_end|> 
<|im_start|>user 
{PROMPT}<|im_end|> 
<|im_start|>assistant

Uses

Direct Use
This model is meant to be an efficient and fine-tunable helpful assistant. It is designed to excel in user assistance and reasoning, and rely less on internal knowledge and factuals. Thus, for knowledge retrieval purposes, it should be used with Retrieval Augmented Generation.

Downstream Use
Given the size of this model, it is possible to launch multiple instances of it for use in agentic context without breaking the compute bank.

Recommendations

It is recommended to finetune this model for domain adaption, and use it for a specialized tasks.
To reap full performance, use a repetition penalty of 1.3 rather than 1.

Training Data

Pre-Train Data
Dataset: pints-ai/Expository-Prose-V1

Fine-Tune Data
Corpora:

DPO Data
Dataset: HuggingFaceH4/ultrafeedback_binarized

Training Procedure

Both Pre-Train and Finetuning used our fork of the LitGPT Framework. For DPO, we used the methods set out in The Alignment Handbook. More details can be found in our paper.
