Ask HN: How are you using LLMs in production?

I’m curious how people are leveraging LLMs in production. We’re all familiar with using them to write code through your IDE, or agent, etc… but what applications have you built that use LLMs as part of the functionality?

    - What applications/industries have you found them to be the most useful in?
    - What tools do you use for orchestration? LangGraph/CrewAI/built your own/etc?
    - What models? Centralized or locally deployed?
