I have been a fan of Ruby for many years, but in this fast paced era the Ruby ecosystem always struggled with the dependency versioning. Gems I relied on were never available or compatible with the rest of the ecosystem.

Why would anyone still build in dynamically typed languages in 2026? Why relinquish the crystal clear signals that static typing is able to provide to the LLM?

You static typed evangelists have lost your damn minds. You seem to have completely misunderstood what this library even is because you have some primal urge to boast static typing at every chance.

You can build high quality software with dynamically typed languages, and Ruby is an absolute dream to read and write.

Why do you think that follows?

I was on team dynamic typing for about 12 years, and Ruby was a big part of that. I still think dynamic languages can be wonderful to read and write.

But after using modern statically typed languages with good inference, I changed my mind. Many of my old objections were really objections to verbose type systems, not static typing itself. With inference, you can keep a lot of the readability while gaining safer refactoring, better tooling, and earlier feedback.

That doesn’t mean dynamic languages can’t produce high-quality software. They obviously can. But I don’t think appreciating modern static typing is just evangelism.

And yes, I understand what this library is about, it's for "beautiful" easy to use interface to AI providers for Ruby apps. It's the popular play nowadays with litellm, bifrost, gomodel and vercel gateway. We have at least couple AI gateways, libraries like that every week on HN.

I didn't misunderstand what this library is about. I assume the authors are using LLM's to help author their code in general, even meta-frameworks like this.

Static typed languages had been around a long time before Python, JS and Ruby gained popularity. All three of the latter now support some form of type hints.

Why did people switch to these languages in the first place and what's driving the current back-to-typed-languages trend?

Well, LLMs have an obscene amount of context built into their weights about Ruby on Rails, and can work within it extremely quickly.

Even as rails dev, I am seeing that you might be right. It’s really hard to find specific pros nowadays that Ruby brings to the table. All that talk about conventions over configurations and vast presence of Rails in weights is fun, but if writing speed isn’t an issue anymore, then Ruby on Rails has serious problems with larger codebases

Codebases like Stripe?

they introduced static typing (Sorbet) to avoid problems, it's completely different app and looks nowhere close to what you experience in standard Rails app

This is not a tool for using LLMs to write Ruby code.

No, it's just a tool someone posted that's written in Ruby, with a strong signal that the authors are LLM proponents. It could have been a todo list and I'd still have the same question.
