## How to use |
|
|
|
This model can be easily used and deployed using HuggingFace's ecosystem. This needs `transformers` and `accelerate` installed. The model can be downloaded as follows: |
|
|
|
```python |
|
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer |
|
|
|
checkpoint = "..." # "checkpoint_1006000" for example |
|
model_name = "bigscience/mt0-xxl" |
|
model = AutoModelForSeq2SeqLM.from_pretrained(model_name, revision=checkpoint, torch_dtype="auto", device_map="auto") |
|
tokenizer = AutoTokenizer.from_pretrained(model_name, revision=checkpoint) |
|
|
|
inputs = tokenizer.encode("Commentaire: C'est la meilleure crêpière que j'ai jamais eu. Je l'adore.\nCe commentaire est-il positif ou négatif?", return_tensors="pt") |
|
outputs = model.generate(inputs) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
## Intended Use |
|
|
|
This model is being created in order to enable public research on large language models (LLMs). LLMs are intended to be used for language generation or as a pretrained base model that can be further fine-tuned for specific tasks. Use cases below are not exhaustive. |
|
|
|
### Direct Use |
|
|
|
- Text generation |
|
|
|
- Exploring characteristics of language generated by a language model |
|
|
|
- Examples: Cloze tests, counterfactuals, generations with reframings |
|
|
|
### Downstream Use |
|
|
|
- Tasks that leverage language models include: Information Extraction, Question Answering, Summarization |

|
|
|
- Indirect users should be made aware when the content they're working with is created by the LLM. |
|
|
|
- Users should be aware of [Risks and Limitations](#risks-and-limitations), and include an appropriate age disclaimer or blocking interface as necessary. |
|
|
|
- Models trained or finetuned downstream of MT0 should include an updated Model Card. |
|
|
|
- Users of the model should provide mechanisms for those affected to provide feedback, such as an email address for comments. |

# Glossary and Calculations |
|
|
|
*This section defines common terms and how metrics are calculated.* |
|
<details> |
|
<summary>Click to expand</summary> |
|
|
|
- <a name="loss">**Loss:**</a> A calculation of the difference between what the model has learned and what the data shows ("groundtruth"). The lower the loss, the better. The training process aims to minimize the loss. |
|
|
|
- <a name="perplexity">**Perplexity:**</a> This is based on what the model estimates the probability of new data is. The lower the perplexity, the better. If the model is 100% correct at predicting the next token it will see, then the perplexity is 1. Mathematically this is calculated using entropy. |
|
|
|
- <a name="high-stakes">**High-stakes settings:**</a> Such as those identified as "high-risk AI systems" and "unacceptable risk AI systems" in the European Union's proposed [Artificial Intelligence (AI) Act](https://artificialintelligenceact.eu/annexes/). |

## Intermediate checkpoints |
|
|
|
For academic (or any) usage, we published the intermediate checkpoints, corresponding to the model state at each 1000 steps. There are available as branches in this repository. You can use them using `transformers`: |
|
|
|
```python |
|
from transformers import AutoModel |
|
|
|
checkpoint = "..." # "checkpoint_1006000" for example |
|
model = AutoModel.from_pretrained("bigscience/mt0-xxl", revision=checkpoint, torch_dtype="auto", device_map="auto") |
|
``` |
|
|
|
## Dataset Creation |
|
|
|
// TODO @niklas: Point to the arxiv paper |
|
|
|
## Original checkpoints |
|
|
|
The checkpoints in this repo correspond to the HuggingFace Transformers format. We'll provide T5X checkpoints as well. |
