ЁЯЪА Aya 101
Aya is a massively multilingual generative language model capable of following instructions in 101 languages. It outperforms other models like mT0 and BLOOMZ in various evaluations, despite covering twice as many languages. The model is trained on multiple datasets and released under the Apache-2.0 license to promote multilingual technologies.

ЁЯЪА Quick Start
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
checkpoint = "CohereLabs/aya-101"
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
aya_model = AutoModelForSeq2SeqLM.from_pretrained(checkpoint)
tur_inputs = tokenizer.encode("Translate to English: Aya cok dilli bir dil modelidir.", return_tensors="pt")
tur_outputs = aya_model.generate(tur_inputs, max_new_tokens=128)
print(tokenizer.decode(tur_outputs[0]))
hin_inputs = tokenizer.encode("рднрд╛рд░рдд рдореЗрдВ рдЗрддрдиреА рд╕рд╛рд░реА рднрд╛рд╖рд╛рдПрдБ рдХреНрдпреЛрдВ рд╣реИрдВ?", return_tensors="pt")

Model Summary
The Aya model is a massively multilingual generative language model that follows instructions in 101 languages. It outperforms mT0 and BLOOMZ in a wide variety of automatic and human evaluations despite covering double the number of languages. The Aya model is trained using xP3x, Aya Dataset, Aya Collection, a subset of DataProvenance collection and ShareGPT-Command. We release the checkpoints under an Apache-2.0 license to further our mission of multilingual technologies empowering a multilingual world.
Model Details
Finetuning
- Architecture: Same as mt5-xxl
- Number of Samples seen during Finetuning: 25M
- Batch size: 256
- Hardware: TPUv4-128
- Software: T5X, Jax
Data Sources
The Aya model is trained on the following datasets:
All datasets are subset to the 101 languages supported by mT5. See the paper for details about filtering and pruning.
Evaluation
We refer to Section 5 from our paper for multilingual eval across 99 languages тАУ including discriminative and generative tasks, human evaluation, and simulated win rates that cover both held-out tasks and in-distribution performance.
Bias, Risks, and Limitations
For a detailed overview of our effort at safety mitigation and benchmarking toxicity and bias across multiple languages, we refer to Sections 6 and 7 of our paper: Aya Model: An Instruction Finetuned Open-Access Multilingual Language Model.
We hope that the release of the Aya model will make community-based redteaming efforts possible, by exposing an open-source massively-multilingual model for community research.
