Token Ruby: First Principles of AI and Claude Code Hot Takes
A lot is happening in the AI world. OpenAI released GPT-5, along with two open-source models: gpt-oss-20b and gpt-oss-120b.
I also wrote a recap of the recent SF AI Ruby Hackathon on my blog. If you’re into Ruby and AI, come join the SF Ruby Slack group and be part of the conversation.

I’m reading AI engineering book by Chip Huyen. It hits just the right level of detail—not the fluffy “prompt engineering vibes” coding hikes, and not the super-nerdy PhD-level machine learning either. It’s a great read if you want to learn how to leverage LLMs to build better products.
