We are using ruby to build a powerful AI toolset in the construction space, and we love how simple all of the SaaS parts are and not reinventing the wheel, but the ruby LLM SDK ecosystem is a bit lagging, so we've written a lot of our own low-level tools.
Great to see someone pushing Ruby in this space. Not after anything permanent, but if you're ever after "plugging gaps" with contract work, complex Ruby projects is what I enjoy the most.
