What's with the failing CI?

Hmm.. I think it might be related to this: ggml-org/llama.cpp#3484

So we may need to update the falcon gguf model file.

EDIT: i.e. updating the deps caused this.

Yup.. We will have to update the falcon model with this: https://gpt4all.io/models/gguf/gpt4all-falcon-newbpe-q4_0.gguf
