# pszemraj/gpt2-medium-vaguely-human-dialogue

This model is a fine-tuned version of [gpt2-medium](https://huggingface.co/gpt2-medium) on a parsed version of Wizard of Wikipedia. Because the batch size was so large, it learned a general understanding of words that makes sense together but does not specifically respond to anything - sort of like an alien learning to imitate human words to convince others that it is human.

It achieves the following results on the evaluation set:
- Loss: 4.3281

## Model description

-  a decent example of what happens when your batch size is too large and the global optima does not reflect specific prompts / use cases.

## Intended uses & limitations

- there are no intended uses


## Training and evaluation data

- a parsed version of the wizard of Wikipedia dataset
