I was playing around with LMStudio, an ai chat system you can run on your own computer. It can use various freely available LLM models to provide chat assistance like chatgpt. I asked it about lasagne... yikes!
It surprised me how much it knew about gardening and plants, but I'd still check the details about specific plants before acting on it. I think it probably offers reasonable general advice.
Most of the LLM models are very much aimed at customer support situations, but there are some that are tailored to role-play games and story telling which is interesting. Lots of LLM models are adapted versions of the main basic models with specific retraining for specific tasks. It's all quite interesting to be able to run it on your own computer, but I don't know if I see myself using it much.
Check out https://lmstudio.ai/ if you're interested. Once downloaded and running you'll need to download a LLM model, the mistral one is a good place to start, which you can do inside the app. Then load in the model and get chatting. Note that most models get upset with swearing but there are retrained versions that are fine with it.
