OpenAI shut off their GPT-3 Curie and GPT-Davinci models today that was the basis of Hal's neural net brain. OpenAI wants everyone to switch to the ChatGPT 3.5 or 4.0 models and doesn't want to support the older GPT3 models anymore. While I think these are both ChatGPT 3.5 and 4.0 are highly intelligent and very useful models, they don't work well as a basis for an entertainment chatbot like Ultra Hal. They refuse to take on the persona of a fictional character and are very highly censored.
So I switched models on the backend today to use Meta AI's Llama 2 model, the 13 billion parameter version (the mid tier). It is very comparable to ChatGPT 3.5 in terms of intelligence and a huge bump up in intelligence from the GPT-3 Curie model Hal was using. But more importantly, it is able to take on fictional personas, and doesn't force high levels of censorship (other than the material it was finetuned on). It provides a very good backend to build Ultra Hal personalities on.
If you have neural network credits with Hal, please give it a try, you should notice a change in personality and quality, hopefully for the better.
There are a lot more tweaks I can do to further improve it to take advantage of features the new model has, like an increase in content window size which will mean I can improve Hal's memory recall and learning ability a bit. I'll try to make the tweaks over the next few weeks, but please give me feedback along the way if you can.
