I started trying to make a quick localish chatgpt. For strange reasons I have access to a server with two gpus. I took the langchain chatgpt example and plugged in an instruction-tuned huggingface model. There is a configuration issue with the server and I’m not sure how much vram and ram it is using, but looking at the model I’d expect a little more than 60GB although the model is sharded into 10GB chunks so may run on less. In my confused manner I made versioned examples where each change was very small. The code I last tried is version 3. It’s just a langchain example with a huggingface model. The example is from https://langchain.readthedocs.io/en/latest/modules/memory/examples/chatgpt_c... . It turns out the model I chose is tuned to refuse to answer many questions. Here’s some output pasted from a tmux session. It’s very interesting how when you do this, the default config shows you how the bot functions as it replies. Very interesting. The output is garbled from the tmux pasting.
