# GPT-J 6B - Janeway
|
6 |
+
## Model Description
|
7 |
+
GPT-J 6B-Janeway is a finetune created using EleutherAI's GPT-J 6B model.
|
8 |
+
## Training data
|
9 |
+
The training data contains around 2210 ebooks, mostly in the sci-fi and fantasy genres. The dataset is based on the same dataset used by GPT-Neo-2.7B-Picard, with 20% more data in various genres.
|
10 |
+
Some parts of the dataset have been prepended using the following text: `[Genre: <genre1>,<genre2>]`
|
11 |
+
### How to use
|
12 |
+
You can use this model directly with a pipeline for text generation. This example generates a different sequence each time it's run:
|
13 |
+
```py
|
14 |
+
>>> from transformers import pipeline
|
15 |
+
>>> generator = pipeline('text-generation', model='KoboldAI/GPT-J-6B-Janeway')
|
16 |
+
>>> generator("Welcome Captain Janeway, I apologize for the delay.", do_sample=True, min_length=50)
|
17 |
+
[{'generated_text': 'Welcome Captain Janeway, I apologize for the delay."\nIt's all right," Janeway said. "I'm certain that you're doing your best to keep me informed of what\'s going on."'}]
|
18 |
+
```
|
19 |
+
### Limitations and Biases
|
20 |
+
|
21 |
+
The core functionality of GPT-J is taking a string of text and predicting the next token. While language models are widely used for tasks other than this, there are a lot of unknowns with this work. When prompting GPT-J it is important to remember that the statistically most likely next token is often not the token that produces the most "accurate" text. Never depend upon GPT-J to produce factually accurate output.
|
22 |
+
|
23 |
+
GPT-J was trained on the Pile, a dataset known to contain profanity, lewd, and otherwise abrasive language. Depending upon use case GPT-J may produce socially unacceptable text. See [Sections 5 and 6 of the Pile paper](https://arxiv.org/abs/2101.00027) for a more detailed analysis of the biases in the Pile.
|
24 |
+
|
25 |
+
As with all language models, it is hard to predict in advance how GPT-J will respond to particular prompts and offensive content may occur without warning. We recommend having a human curate or filter the outputs before releasing them, both to censor undesirable content and to improve the quality of the results.
|
26 |
+
|
27 |
+
### BibTeX entry and citation info
|
28 |
+
The model uses the following model as base:
|
29 |
+
```bibtex
|
30 |
+
@misc{gpt-j,
|
31 |
+
author = {Wang, Ben and Komatsuzaki, Aran},

+

|
