Do you have LLMs in prod at work? If so, what for? [D]

feel free to expand in the comments with info like the task (RAG, chatbot, tooling, seq2seq, etc) model size, deployment strategies, shortcomings, future plans, etc.

In my case:
Task: RAG
Model: zephyr 7B
Deployment: vLLM
Future plans: Pretraining on internal documents + chat finetuning
