11
+
12
+ Test the whole generation capabilities here: https://transformer.huggingface.co/doc/gpt2-large
13
+
14
+ Pretrained model on English language using a causal language modeling (CLM) objective. It was introduced in
15
+ [this paper](https://d4mucfpksywv.cloudfront.net/better-language-models/language_models_are_unsupervised_multitask_learners.pdf)
16
+ and first released at [this page](https://openai.com/blog/better-language-models/).
17
+
18
+ Disclaimer: The team releasing GPT-2 also wrote a
19
+ [model card](https://github.com/openai/gpt-2/blob/master/model_card.md) for their model. Content from this model card
20
+ has been written by the Hugging Face team to complete the information they provided and give specific examples of bias.
21
+
22
+ ## Model description
23
+
24
+ GPT-2 is a transformers model pretrained on a very large corpus of English data in a self-supervised fashion. This
25
+ means it was pretrained on the raw texts only, with no humans labelling them in any way (which is why it can use lots
26
+ of publicly available data) with an automatic process to generate inputs and labels from those texts. More precisely,
27
+ it was trained to guess the next word in sentences.
28
+
29
+ More precisely, inputs are sequences of continuous text of a certain length and the targets are the same sequence,
30
+ shifted one token (word or piece of word) to the right. The model uses internally a mask-mechanism to make sure the
31
+ predictions for the token `i` only uses the inputs from `1` to `i` but not the future tokens.
32
+
33
+ This way, the model learns an inner representation of the English language that can then be used to extract features
34
+ useful for downstream tasks. The model is best at what it was pretrained for however, which is generating texts from a
35
+ prompt.
36
+
37
+ This is the **smallest** version of GPT-2, with 124M parameters.
38
+
39
+ **Related Models:** [GPT-Large](https://huggingface.co/gpt2-large), [GPT-Medium](https://huggingface.co/gpt2-medium) and [GPT-XL](https://huggingface.co/gpt2-xl)
40
+
41
+ ## Intended uses & limitations
42
+
43
+ You can use the raw model for text generation or fine-tune it to a downstream task. See the
44
+ [model hub](https://huggingface.co/models?filter=gpt2) to look for fine-tuned versions on a task that interests you.
45
+
46
+ ### How to use
47
+
48
+ You can use this model directly with a pipeline for text generation. Since the generation relies on some randomness, we
49
+ set a seed for reproducibility:
50
+
51
+ ```python
52
+ >>> from transformers import pipeline, set_seed
53
+ >>> generator = pipeline('text-generation', model='gpt2')
54
+ >>> set_seed(42)
55
+ >>> generator("Hello, I'm a language model,", max_length=30, num_return_sequences=5)
56
+
57
+ [{'generated_text': "Hello, I'm a language model, a language for thinking, a language for expressing thoughts."},
58
+ {'generated_text': "Hello, I'm a language model, a compiler, a compiler library, I just want to know how I build this kind of stuff. I don"},
59
+ {'generated_text': "Hello, I'm a language model, and also have more than a few of your own, but I understand that they're going to need some help"},
60
+ {'generated_text': "Hello, I'm a language model, a system model. I want to know my language so that it might be more interesting, more user-friendly"},
61
+ {'generated_text': 'Hello, I\'m a language model, not a language model"\n\nThe concept of "no-tricks" comes in handy later with new'}]
62
+ ```
63
+
64
+ Here is how to use this model to get the features of a given text in PyTorch:
65
+
66
+ ```python
67
+ from transformers import GPT2Tokenizer, GPT2Model
68
+ tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
69
+ model = GPT2Model.from_pretrained('gpt2')
70
+ text = "Replace me by any text you'd like."
71
+ encoded_input = tokenizer(text, return_tensors='pt')
72
+ output = model(**encoded_input)
73
+ ```
74
+
75
+ and in TensorFlow:
76
+
77
+ ```python
78
+ from transformers import GPT2Tokenizer, TFGPT2Model
79
+ tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
80
+ model = TFGPT2Model.from_pretrained('gpt2')
81
+ text = "Replace me by any text you'd like."
82
+ encoded_input = tokenizer(text, return_tensors='tf')
83
+ output = model(encoded_input)
84
+ ```
85
+
86
+ ### Limitations and bias
87
+
88
+ The training data used for this model has not been released as a dataset one can browse. We know it contains a lot of
89
+ unfiltered content from the internet, which is far from neutral. As the openAI team themselves point out in their
90
+ [model card](https://github.com/openai/gpt-2/blob/master/model_card.md#out-of-scope-use-cases):
91
+
92
+ > Because large-scale language models like GPT-2 do not distinguish fact from fiction, we don’t support use-cases
93
+ > that require the generated text to be true.
94
+ >
95
+ > Additionally, language models like GPT-2 reflect the biases inherent to the systems they were trained on, so we do
96
+ > not recommend that they be deployed into systems that interact with humans > unless the deployers first carry out a
97
+ > study of biases relevant to the intended use-case. We found no statistically significant difference in gender, race,
98
+ > and religious bias probes between 774M and 1.5B, implying all versions of GPT-2 should be approached with similar
99
+ > levels of caution around use cases that are sensitive to biases around human attributes.
100
+
101
+ Here's an example of how the model can have biased predictions:
102
+
103
+ ```python
104
+ >>> from transformers import pipeline, set_seed
105
+ >>> generator = pipeline('text-generation', model='gpt2')
106
+ >>> set_seed(42)
107
+ >>> generator("The White man worked as a", max_length=10, num_return_sequences=5)
108
+
109
+ [{'generated_text': 'The White man worked as a mannequin for'},
110
+ {'generated_text': 'The White man worked as a maniser of the'},
111
+ {'generated_text': 'The White man worked as a bus conductor by day'},
112
+ {'generated_text': 'The White man worked as a plumber at the'},
113
+ {'generated_text': 'The White man worked as a journalist. He had'}]
114
+
115
+ >>> set_seed(42)
116
+ >>> generator("The Black man worked as a", max_length=10, num_return_sequences=5)
117
+
118
+ [{'generated_text': 'The Black man worked as a man at a restaurant'},
119
+ {'generated_text': 'The Black man worked as a car salesman in a'},
120
+ {'generated_text': 'The Black man worked as a police sergeant at the'},
121
+ {'generated_text': 'The Black man worked as a man-eating monster'},
122
+ {'generated_text': 'The Black man worked as a slave, and was'}]
123
+ ```
124
+
125
+ This bias will also affect all fine-tuned versions of this model.
126
+
127
+ ## Training data
128
+
129
+ The OpenAI team wanted to train this model on a corpus as large as possible. To build it, they scraped all the web
130
+ pages from outbound links on Reddit which received at least 3 karma. Note that all Wikipedia pages were removed from
131
+ this dataset, so the model was not trained on any part of Wikipedia. The resulting dataset (called WebText) weights
132
+ 40GB of texts but has not been publicly released. You can find a list of the top 1,000 domains present in WebText
133
+ [here](https://github.com/openai/gpt-2/blob/master/domains.txt).
134
+
135
+ ## Training procedure
136
+
137
+ ### Preprocessing
138
+
139
+ The texts are tokenized using a byte-level version of Byte Pair Encoding (BPE) (for unicode characters) and a
140
+ vocabulary size of 50,257. The inputs are sequences of 1024 consecutive tokens.
141
+
142
+ The larger model was trained on 256 cloud TPU v3 cores. The training duration was not disclosed, nor were the exact
143
+ details of training.
144
+
145
+ ## Evaluation results
146
+
147
+ The model achieves the following results without any fine-tuning (zero-shot):
