Hi, I’m Kaleb.

Portrait of Kaleb Cole

I make things, write down what I learn, and follow whatever has me curious right now.

I’m a software engineer at Microsoft, building what interests me and designing how we work with agents.

Creating Muse: The Fastest-Growing AI Product Since ChatGPT | Alexandr Wang, Meta (external site)

By David Senra

My thoughts

Crazy that Alexandr Wang is under 30. My takeaways: he has 200 direct reports in Meta Superintelligence Labs because he does not believe in bureaucracy. Some of those reports are technical leads, so they have technical management rather than people management. He said Muse needed a singular point of view, not a Frankenstein of features from different parties, or “PM hell.” I also found it really interesting that they are coupling the model and harness, with training built around personal agents. I am really loving Muse and really enjoyed this pod.

You Said No MCP! (external site)

By Earendil Engineering

My thoughts

Read this and now mcp-pilled. What Mario and Armin say goes. Now I’m going to learn about code mode with MCP. From initial research, looks like a solved problem for all the issues with MCP. Composability through a JavaScript function, low latency from parallel tool calling, and context management by keeping tokens out of the window

#435 Mark Zuckerberg's Empire (external site)

By David Senra

My thoughts

Interesting to hear about Zuckerberg's obsession with the Roman Empire. The big takeaway for me is the dictator's dilemma. The more power you have, the more people are incentivized to tell you what you want to hear. You have to get close to the metal and go to the factory floor, rather than just believe the reports coming up to you.
