Stock DeepSeek refused to write the phishing email. Brian switched to the abliterated twin of the same model and it wrote the lure, reset link included. managerxbuilder.substack.com…

Klaus thinks dedicated tech debt weeks should be gone. Kunal's not sure, because you're shipping a lot more than you used to.

An abliterated model has the refusal weights cut out. Brian ran one on an isolated home lab next to stock DeepSeek. Same model family. One writes the phishing email, the other won't.

Brian deleted all of his custom sub-agents this week. He still runs vanilla sub-agents constantly, because a test writer shouldn't know what the implementer did. managerxbuilder.substack.com…

Brian's personal wiki ranks sources by trust. His own words count most, then his calls, then the podcasts and newsletters he trusts. Random web results never get in.

Tomorrow on Manager Builder, Kunal and Brian debate generalized vs specialized agents. "Most of our best practices are just best practices for humans."

In planning, Claude should ask what you want to do and then stop. Once it hands you a recommended option, it's too easy to just hit Enter. managerxbuilder.substack.com…

One-shot vs progressive on the same monitoring stream. One-shot: four false pages, missed the leak, a couple of cents. Progressive: one page, no false positives, about 50 cents. managerxbuilder.substack.com…

Asked a fast classifier to make one call per event. Four false alarms, and it missed the memory leak.

AI slop can cost you a client. Manager: keep a quality gate when models write the code. managerxbuilder.substack.com…

Why personal software matters: remove friction in your own workflow, and get a low-risk lab to try AI before work. Builder. managerxbuilder.substack.com…

Squarespace had no API, so I was the human in the loop adding zero value. One day-long side project with AI later, the site runs on Astro 5 + Cloudflare Pages. Builder take on personalized software.

Are you leading Claude, or is it leading you? Manager take: lead the bots instead of being led by them. managerxbuilder.substack.com…

Cool eval. Simply ask an LLM “Land or Water?” and give it a latitude and longitude coordinate as text. Ask 16,200 times, plot as image. The models know. From compressing the internet.

A human avatar sending dehumanized Claude-speak in Slack isn't helpful — it feels disrespectful. Manager take on AI slop in human channels.

Functional constraints vs architectural ones — which actually breaks your agent workflow?

What does software development look like when agents write code all day—and much of it gets merged overnight? Developers become team leads: define intent, then hand work to a “night shift.” managerxbuilder.substack.com…

Here's a 45-second TL;DR on Jev. I find the core idea beautifully simple, but the video made it really hard to understand. Hope you find it helpful.
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

Here's what OpenAI's agentic software factory looks like, today. Details: newsletter.pragmaticengineer… (thanks to all the OpenAI folks who explained how it works! And Perf Factory looks especially interesting to me)

"Man, you must have burned thousands of dollars in tokens to generate that." Fishslop would have been under $30 to generate. Wouldn't even have noticed the dent on the $200 sub.
GPT-6 Astra is world class at Blender and 3 dimensional reasoning. This was a 1-shot game it created, all running in browser.
