Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux

I've been working on https://notebooker.ai if anyone is interested in giving some feedback. I tried to post a Show HN yesterday with details about how I built it, but was auto-flagged and not sure what rules I broke. Everything that I've built on top of open-notebook, like the plugin system for your own "creators" (aka, podcasts, infographics, etc) is at https://github.com/Notebooker-ai plus a Cloudflare Worker AI deployer to play with different models. Been working on it for about six months.
