# FLAN-T5
|
|
|
|
## Overview
|
|
|
|
FLAN-T5 was released in the paper [Scaling Instruction-Finetuned Language Models](https://arxiv.org/pdf/2210.11416.pdf) - it is an enhanced version of T5 that has been finetuned in a mixture of tasks.
|
|
|
|
One can directly use FLAN-T5 weights without finetuning the model:
|
|
|
|
```python
|
|
>>> from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
|
|
|
|
>>> model = AutoModelForSeq2SeqLM.from_pretrained("google/flan-t5-small")
|
|
>>> tokenizer = AutoTokenizer.from_pretrained("google/flan-t5-small")
|
|
|
|
>>> inputs = tokenizer("A step by step recipe to make bolognese pasta:", return_tensors="pt")
|
|
>>> outputs = model.generate(**inputs)
|
|
>>> print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
|
|
['Pour a cup of bolognese into a large bowl and add the pasta']
|
|
```
|
|
|
|
FLAN-T5 includes the same improvements as T5 version 1.1 (see [here](https://huggingface.co/docs/transformers/model_doc/t5v1.1) for the full details of the model's improvements.)
|
|
|
|
Google has released the following variants:
|
|
|
|
- [google/flan-t5-small](https://huggingface.co/google/flan-t5-small)
|
|
|
|
- [google/flan-t5-base](https://huggingface.co/google/flan-t5-base)
|
|
|
|
- [google/flan-t5-large](https://huggingface.co/google/flan-t5-large)
|
|
|
|
- [google/flan-t5-xl](https://huggingface.co/google/flan-t5-xl)
|
|
|
|
- [google/flan-t5-xxl](https://huggingface.co/google/flan-t5-xxl).
|
|
|
|
One can refer to [T5's documentation page](t5) for all tips, code examples and notebooks. As well as the FLAN-T5 model card for more details regarding training and evaluation of the model.
