>>39815002it's two neural networks working in tandem, one is a CNN (convolutional neural network) and the other an LLM (large language model)
the chatbot is a custom LLM but vedal didn't say what its based from, though judging on the quality of the responses I'm assuming it's GPT2 derived or similar (about as much as you can run locally anyways). It's the same tech as
https://chat.openai.com/chat but a lot weaker and barely better than a markov chain (phone autocomplete).
vedal said the CNN learns in real time via backpropagation, but I assume the chatbot is fully pretrained (mostly since realtime learning LLM is an area of ongoing research)(also neuro clearly has late stage dementia)
