+Pile-T5 Base is an Encoder-Decoder model trained on [the Pile](https://pile.eleuther.ai/) using the [T5x](https://github.com/google-research/t5x) library. The model was trained for 2 million steps or roughly 2 trillion tokens using MLM-objective similar to the original T5 model.

+### Uses and limitations
+
+#### Intended use
+
+Pile-T5 was developed primarily for research purposes. It learns an inner 
+representation of the English language that can be used to extract features 
+useful for downstream tasks.
+
+In addition to scientific uses, you may also further fine-tune and adapt 
+Pile-T5 for deployment, as long as your use is in accordance with the 
+Apache 2.0 license. This model works with the [Transformers 
+Library](https://huggingface.co/docs/transformers/index). If you decide to use 
+pre-trained Pile-T5 as a basis for your fine-tuned model, please note that 
+you need to conduct your own risk and bias assessment. 
+
+#### Out-of-scope use
+
+Pile-T5 is **not** intended for deployment as-is. It is not a product 
+and cannot be used for human-facing interactions without supervision.
+
+Pile-T5 has not been fine-tuned for downstream tasks for which language 
+models are commonly deployed, such as writing genre prose, or commercial 
+chatbots. This means Pile-T5 will likely **not** respond to a given prompt 
+the way products such as ChatGPT do. This is because, unlike Pile-T5, 
+ChatGPT was fine-tuned using methods such as Reinforcement Learning from Human 
+Feedback (RLHF) to better “understand” human instructions and dialogue.
+
+This model is English-language only, and thus cannot be used for translation
+or generating text in other languages.
+
+#### Limitations and biases
+
+The core functionality of Pile-T5 is to take a string of text that has been 
+partially replaced with mask tokens and predict a sequence of tokens that would
+replace those mask tokens. Remember that the statistically most likely sequence
+of tokens need not result in the most “accurate” text. Never rely on Pile-T5 to produce 
+factually accurate output.
+
+This model was trained on [the Pile](https://pile.eleuther.ai/), a dataset 
+known to contain profanity and texts that are lewd or otherwise offensive. 
+See [Section 6 of the Pile paper](https://arxiv.org/abs/2101.00027) for a 
+discussion of documented biases with regards to gender, religion, and race. 
+Pile-T5 may produce socially unacceptable or undesirable text, *even if*
+ the prompt itself does not include anything explicitly offensive. 
+
+We recommend curating the outputs of this model before presenting it to a human 
+reader. Please inform your audience that you are using artificially generated 
+text. 
+
+#### How to use
+
+Pile-T5 can be loaded using the `AutoModelForSeq2SeqLM` functionality:
+```python
+from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+
+tokenizer = AutoTokenizer.from_pretrained("EleutherAI/pile-t5-base")
+model = AutoModelForSeq2SeqLM.from_pretrained("EleutherAI/pile-t5-base")
+```
+
+### Training
+
+#### Training dataset
+
+The Pile is a 825GiB general-purpose dataset in English. It was created by 
+EleutherAI specifically for training large language models. It contains texts 
+from 22 diverse sources, roughly broken down into five categories: academic 
+writing (e.g. arXiv), internet (e.g. CommonCrawl), prose (e.g. Project 
+Gutenberg), dialogue (e.g. YouTube subtitles), and miscellaneous (e.g. GitHub, 
+Enron Emails). See [the Pile paper](https://arxiv.org/abs/2101.00027) for 
+a breakdown of all data sources, methodology, and a discussion of ethical 
+implications. Consult [the datasheet](https://arxiv.org/abs/2201.07311) for 
+more detailed documentation about the Pile and its component datasets. The 
+Pile can be downloaded from the [official website](https://pile.eleuther.ai/), 
+or from a [community mirror](https://the-eye.eu/public/AI/pile/).
+
+The Pile was deduplicated before being used to train Pile-T5.
+
+#### Training procedure
+
+Pile-T5 was trained with a batch size of approximately 1M tokens 
+(2048 sequences of 512 tokens each), for a total of 2,000,000 steps. Pile-T5 was trained
+with the span-corruption objective.
+
+#### Training checkpoints
+
+Intermediate checkpoints for Pile-T5 are accessible within this repository. 
+There are in total 200 checkpoints that are spaced 10,000 steps. For T5x-native
+checkpoints that can be used for finetuning with the T5x library, refer to [here](https://huggingface.co/lintang/pile-t5-base-t5x/tree/main)
