Unsupervised Sentiment Neuron (2017)

Every now and then, I think it's useful to look at what great work looked like in its first form.

In retrospect, this result was the first step toward the LLMs that are now the dominant approach in AI.

In 2017, this was a very modest result and probably didn't seem very promising. It took real courage and tenacity on OpenAI's part to keep at it for the next 5 years.
