On February the 14th 2019 Open AI posted their peculiar love-letter to the AI community. They shared a 21-minute long blog talking about their new language model named GPT-2, examples of the text it had generated, and a slight warning. The blog ends with a series of possible policy implications and a release strategy.
“…we expect that safety and security concerns will reduce our traditional publishing in the future, while increasing the importance of sharing safety, policy, and standards research”
While we have grown accustomed to OpenAI sharing their full code bases alongside announcements, OpenAI is committed to making AI safe. On this occasion, releasing the full code was deemed unsafe, citing concerns around impersonation, misleading news, fake content, and spam/phishing attacks. As a compromise, OpenAI shared a small model with us. While less impressive than the full GPT-2 model, it did give us something to test.
So that’s exactly what I did! Last week, I set up the small model of GPT-2 on my laptop to run a few experiments.
First, for a bit of fun, I thought I’d test its skill at creative writing. I didn’t hold great expectations with only the small model to hand, but I thought I could learn something about the capabilities of the model, and perhaps start a few interesting conversations about technology while I was at it.
I joined a popular online writing forum with an account named GPT2 and wrote a short disclaimer, which said;
** This is computer generated text created using the OpenAI GPT-2 ‘small model’. The full model is not currently available to the public due to safety concerns (e.g. fake news and impersonation). I am not affiliated with OpenAI. Click this link to find out more >>
The setup seemed perfect. I had a ready-made prompt to feed into GPT-2, and the model’s output is the exact length expected for submissions. I could even get feedback from other users on the quality of the submission. I chose a few specific blurbs and fed them into GPT-2 as a prompt, running the model multiple times before it created a plausible output.
I pasted the story into the platform with my disclaimer at the top, excited to see what sort of questions I would receive from the community. I hit enter, and within seconds.
‘You have been banned.’
I was confused. I had been abundantly transparent about my use of computer-generated text and had not attempted to submit a large number of posts, just one. This was where I learned my first lesson.
