alt Hacker NewsYour PR #151 was opened May 4, 2025 and merged 2 days later.
The repeated `chat.to_llm` message bug was reported Apr 30 2025, and fixed May 6, 2025, about 27 minutes after your comment.
It only showed up when reusing the same Rails chat object for multiple turns in the same Ruby object lifetime, e.g. `chat.ask("first"); chat.ask("second")` inside one controller action or one background job.
The usual flow is one turn per request/job, where the record is reloaded each time. Also, it did not overwrite records; it duplicated messages in the in-memory request context.
Gemini tool calling shipped in 1.0, schema support landed in 1.4, and observability landed in 1.16.
As for "the most trivial of applications": check the docs. RubyLLM goes well beyond that, and several multi-million-dollar companies use it in production every day.

I don't remember every interaction I had with you folks, but that wasn't the only one. Also, the same PR was reverted a bit later, IIRC -- I think I made a mistake in my PR or it wasn't compatible with some other use case, so that's fine, but the overall theme of the interactions (again, in my recollection) was that I was personally moving much faster than you, and using your library was hurting more than helping. So I stopped.

That happens all the time. Without it, you can't pass things around to functions that add to the chat, for example.

This may be your usual flow, but it doesn't have to be everybody's usual flow. No offense, but you're currently reminding me of what I interpreted as "chilly reactions" at the time.

Great! I did them myself in less time. It's entirely possible that your library, today, is the tool I needed then.

OK. Cool. If they want to use the software, I'm sure nothing I say will convince them otherwise.
The decision to audit (frankly, aggressively) this guy out the gate with this comment on a discussion thread is not a good look. It's a very unnecessary way to tarnish the reputation of the devs by picking fights with someone sharing their experience. If you can't see how you did that, perhaps you should ask an LLM to help.
