# Amber-Data

<img src="amber_logo.png" alt="amber logo" width="300"/>

This dataset contains the fully prepared data sequence used to train Amber, an
LLM360 model. 

## About LLM360
LLM360 is an initiative for comprehensive and fully open-sourced LLMs, 
where all training details, model checkpoints, intermediate results, and 
additional analyses are made available to the community. Our goal is to advance 
the field by inviting the community to deepen the understanding of LLMs 
together. As the first step of the project LLM360, we release all intermediate 
model checkpoints, our fully-prepared pre-training dataset, all source code and
configurations, and training details. We are
committed to continually pushing the boundaries of LLMs through this open-source 
effort.

# Loading Amber's Pretraining Data

Below is an example of how to download, sample, and detokenize any subset of AmberDatasets corresponding to an Amber checkpoint. Just set the `CHECKPOINT_NUM` to the subset you are interested in (0-359) and point `CHECKPOINT_PATH` to the local checkpoint folder. 

```python
import random
from transformers import AutoTokenizer
from datasets import load_dataset

CHECKPOINT_NUM = 0  # Pretraining dataset for checkpoint
NUM_SAMPLES = 10  # Number of random samples to decode
CHECKPOINT_PATH = "/path/to/ckpt_000/"  # Local path to a Amber checkpoint

dataset = load_dataset(
    "LLM360/AmberDatasets",
    data_files=f"train/train_{CHECKPOINT_NUM:03}.jsonl",
    split=None,
)

tokenizer = AutoTokenizer.from_pretrained(CHECKPOINT_PATH)
samples = set(random.choices(range(len(dataset["train"])), k=NUM_SAMPLES))

for i, line in enumerate(dataset["train"]):
    if i in samples:
        tokens = line["token_ids"]
        print(f"{i}:{tokenizer.decode(tokens)}")
```
