I do use a local LLM for coding support. There are limitations, but it can do some scaffolding tests and templating or provide additional documentation beyond the usual function reference. I rarely let it implement or autocomplete my code.

Granted, this is most helpful in common languages and common environments. In more exotic environments (i.e. custom industrial hardware interfaces) the AI usually is of limited help.

For writing an offer, an AI can probably help. It will absolutely ruin your day if it has to do basic calculations if these type of queries isn't forwarded to a another specialized AI that isn't an LLM. It does often find fitting headers for your data visualizations though.

It can be useful to solve the "blank page problem" i.e. to get an initial set of data to challenge. However it has zero customer data, or internal code to help with anything like that.

No. Like the marketing folks, it talks pretty, but it lies.
