# T5

The T5 models are encoder-decoder models pre-trained on a mixture of
unsupervised and supervised tasks.[^1] These models work well on a variety of
tasks by prepending task-specific prefixes to the input, e.g.:
`translate English to German: …`, `summarize: ….`, etc.

This example also supports the FLAN-T5 models variants.[^2]

## Generate

Generate text with:

```sh
python t5.py --model t5-small --prompt "translate English to German: A tasty apple"
```

This should give the output: `Ein leckerer Apfel`

To see a list of options run:

```sh
python t5.py --help
```

The `<model>` can be any of the following:

| Model Name | Model Size  |
| ---------- | ----------
| t5-small   | 60 million  |
| t5-base    | 220 million |
| t5-large   | 770 million |
| t5-3b      | 3 billion   |
| t5-11b     | 11 billion  |

The FLAN variants can be specified with `google/flan-t5-small`,
`google/flan-t5-base`, etc. See the [Hugging Face
page](https://huggingface.co/docs/transformers/model_doc/flan-t5) for a
complete list of models.
