“#9 𝕏 Peter Yang raised a $2M seed round but is holding off on hiring so he can personally learn each role’s pain points. Instead, he’s onboarding AI agents for faster ramp-up and ongoing training improvements.”

#9 𝕏 Peter Yang raised a $2M seed round but is holding off on hiring so he can personally learn each role’s pain points. Instead, he’s onboarding AI agents for faster ramp-up and ongoing training improvements. #6 𝕏 Garry Tan – President & CEO @ycombinator argues that while most AI agent builders focus on the “prefrontal cortex” (planning and reasoning), true leverage comes from building the “cerebellum” that automates mundane, repetitive tasks.

“#15 in Greg Isenberg argues that AI agents have become the primary buyers on the internet, making MCP servers essential for any business wanting visibility.”

#15 in Greg Isenberg argues that AI agents have become the primary buyers on the internet, making MCP servers essential for any business wanting visibility. #16 𝕏 Sebastian Raschka highlights a low-commitment attention modification that you can run for most of training and then switch back to vanilla attention near the end, recovering performance on par with full attention.

“Hugging Face has become the go-to platform for AI agents, giving them access to 1 M HF Spaces to build and run the latest specialized models.”

“#6 𝕏 Cognition : Russell J. Kaplan observes that AI agents are now autonomously kicking off tasks, signaling a shift toward proactive engineering.”

Today's top 10 insights for PM Builders from X and Blogs. #6 𝕏 Cognition : Russell J. Kaplan observes that AI agents are now autonomously kicking off tasks, signaling a shift toward proactive engineering. #7 𝕏 Peter Yang echoes @karrisaarinen (CEO @Linear) that when you can spin up 10 agents in 10 directions, shared clarity on your target users, the problem you’re solving, and your product vision is critical to keep fast execution focused.

“AI agents perform best when they can freely install, run, debug, and deploy code—but they need persistent compute to keep state.”

#5 𝕏 Guillermo Rauch says AI agents perform best when they can freely install, run, debug, and deploy code—but they need persistent compute to keep state.

“#15 𝕏 Peter Yang says PMs must write specs for AI agents rather than engineers and rapidly master core AI skills or risk obsolescence.”

#15 𝕏 Peter Yang says PMs must write specs for AI agents rather than engineers and rapidly master core AI skills or risk obsolescence. He even proposes token spend should eclipse salaries and warns that waterfall methodologies won’t survive the AI revolution.

“#12 𝕏 Santiago argues that AI agents eliminate the need to hand-code orchestration and decision logic, making it much faster and easier for PMs to build and manage complex workflows.”

The newsletter includes a PM-oriented take on agents as workflow automation primitives. The point is that agents can replace custom orchestration and decision trees in application design.
