# Graphcore/gpt2-wikitext-103 |
|
|
|
This model is a fine-tuned version of [gpt2](https://huggingface.co/gpt2) on the [wikitext-103-raw-v1](https://huggingface.co/datasets/wikitext) dataset. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 2.9902 |
|
|
|
## Model description |
|
|
|
GPT2 is a large transformer-based language model. It is built using transformer decoder blocks. BERT, on the other hand, uses transformer encoder blocks. It adds Layer normalisation to the input of each sub-block, similar to a pre-activation residual networks and an additional layer normalisation. |
