## MPT-7B-StoryWriter-65k+ |
|
|
|
MPT-7B-StoryWriter-65k+ is a model designed to read and write fictional stories with super long context lengths. |
|
It was built by finetuning MPT-7B with a context length of 65k tokens on a filtered fiction subset of the [books3 dataset](https://huggingface.co/datasets/the_pile_books3). |
|
At inference time, thanks to [ALiBi](https://arxiv.org/abs/2108.12409), MPT-7B-StoryWriter-65k+ can extrapolate even beyond 65k tokens. |
|
We demonstrate generations as long as 84k tokens on a single node of 8 A100-80GB GPUs in our [blogpost](https://www.mosaicml.com/blog/mpt-7b). |

### Model Description |
|
|
|
The architecture is a modification of a standard decoder-only transformer. |
|
|
|
The model has been modified from a standard transformer in the following ways: |
|
* It uses [FlashAttention](https://arxiv.org/pdf/2205.14135.pdf) |
|
* It uses [ALiBi (Attention with Linear Biases)](https://arxiv.org/abs/2108.12409) and does not use positional embeddings |
|
* It does not use biases |

### PreTraining Data |
|
|
|
For more details on the pretraining process, see [MPT-7B](https://huggingface.co/mosaicml/mpt-7b). |
|
|
|
The data was tokenized using the [EleutherAI/gpt-neox-20b](https://huggingface.co/EleutherAI/gpt-neox-20b) tokenizer. |
|
|
|
#### Training Configuration |
|
|
|
This model was trained on 8 A100-80GBs for about 2 days using the [MosaicML Platform](https://www.mosaicml.com/platform). |
|
The model was trained with sharded data parallelism using [FSDP](https://pytorch.org/docs/stable/fsdp.html) and used the [LION](https://arxiv.org/abs/2302.06675) optimizer. |
|
|
|
### Limitations and Biases |
|
|
|
_The following language is modified from [EleutherAI's GPT-NeoX-20B](https://huggingface.co/EleutherAI/gpt-neox-20b)_ |
|
|
|
MPT-7B-StoryWriter can produce factually incorrect output, and should not be relied on to produce factually accurate information. |
|
MPT-7B-StoryWriter was trained on various public datasets. |
|
While great efforts have been taken to clean the pretraining data, it is possible that this model could generate lewd, biased or otherwise offensive outputs. |
