Here’s the moment from that lesson where I showed for the first time that language model fine tuning gives a state of the art result in classifying IMDB sentiment:Ī language model is trained to guess missing words in a piece of text. OpenAI’s Alec Radford told me that this paper inspired him to create GPT, which Codex is based on. Sebastian Ruder and I then fleshed out the approach and wrote a paper, which was published in 2018 by the Association for Computational Linguistics (ACL). I developed and showed that as part of a fast.ai lesson.

This is of particular interest to me, since in back in 2017 I was the first person to demonstrate that a general purpose language model can be fine-tuned to get state of the art results on a wide range of NLP problems. It may even turn out to be a curse.Ĭopilot is powered by a deep neural network language model called Codex, which was trained on public code repositories on GitHub. However, as we’ll see, I’m not yet convinced that Copilot is actually a blessing. Therefore, I was particularly keen to dive into Copilot. This is particularly exciting for us at fast.ai because it holds the promise that it may lower the barrier to coding, which would greatly help us in our mission. Where Copilot differs is that it can generate entire multi-line functions and even documentation and tests, based on the full context of a file of code. Tabnine has provided “AI powered” code completion for a few years now. GitHub’s Natural Language Semantic Code Search in 2018 demonstrated finding code examples using plain English descriptions. This is certainly not the first “AI powered” program synthesis tool. The grey body of the function has been entirely written for me by Copilot! I just hit Tab on my keyboard, and the suggestion gets accepted and inserted into my code. For example, here I’ve typed the name and docstring of a function which should “ Write text to file fname”:

It is a plugin to Visual Studio Code which auto-generates code for you based on the contents of the current file, and your current cursor location.
