RubyLLM 2.1 is out now and it's missing nothing from LangChain/LangGraph/LangSmith.
- Up to 58x faster and 58x less memory
- Built-in MCP support with MCP Apps up to the latest spec
- Support for Jev and other Decision Models
- a new Evaluation framework
- OpenTelemetry tracing
You can have it all. The capabilities of the big Python frameworks, in a beautiful language like Ruby, integrated seamlessly into your Rails applications.
Update on founding a company in Germany:
The VAT ID arrived. 203 days after I started, almost €12k later.
Then my tax firm asked for my trade registration. First time anyone mentioned it. Legally due the day I started.
Filed it 3 weeks ago. Still waiting. Probably gonna get fined 1000€ for doing business before it.
I’m working to make Rails the best framework for building LLM apps.
Another piece of that puzzle just dropped: Solid Queue 1.6.0 ships my fiber worker PR 🎉
Rails’ default queue can now run long-lived LLM jobs far more efficiently.
