Lots of projects in the works! Too many really. Opus 4.5 has jammed my design episodes into hyper mode. I'm glad I heard Andrew Ng talk about the exhaustion after a day of working with agentic code helpers. That showed up months ago and I still didn't recognize. Now, having to hold so much in my mind at once while it is also growing at a recognizable pace is noticeably stressful. Here is my latest build, a useful agency for questions at high accuracy with 9 different agents available to work in tandem. Special thanks to my friend Enigma Specter who provided the original backend mechanisms. I salvaged his design with a nice web UI and added a web Researcher agent: https://guyzer.pythonanywhere.com/mrce/ You will need to register but it's just an email username and password, no verification loop yet. And you'll need an API key.

Cyclical Adversarial Stepwise Improvement CASI: Live Demo We talk frequently about AI self-correction but few projects provide a robust architectural loop for it. CASI formalizes the process of non-linear refinement: The Generator proposes a solution or concept. The Critic applies structural pressure and targeted feedback. The system cycles automatically until Structural Coherence is reached. You can now test the CASI engine live and see how an autonomous refinement process delivers structurally superior output: Try the CASI web app here: https://guyzer.pythonanywhere.com/casi/

Cover image for Define what your AI must
Define what your AI must always do and never do. PolicyThread watches every live interaction and tells you when it breaks the rules. Organizations deploying AI in production have rules. Legal rules. Brand rules. Safety rules. Compliance rules. Right now enforcing those rules is manual and reactive, someone writes a system prompt, hopes for the best, and finds out the AI broke the rules when a customer complains or a regulator asks. There is no always-on layer watching every AI interaction against a defined policy. No alert when the AI violates a rule. No audit trail proving the organization tried. PolicyThread fixes this.
