THE REAL PROBLEM IN COMPANIES

What I see in companies when AI enters dev

1. 01The team tests AI, but it stays outside the real development workflow
2. 02Relying only on an external API complicates cost, latency, and governance
3. 03Without a ready stack for deploy and review, an agent becomes just a nice-looking demo

I’VE ALREADY SOLVED THIS

This is how it worked with the AskMoses.AI development team

1. 01100% agentic development team
2. 02each dev works with Claude Code on the project
3. 03another Claude reviews the pull request; deploy on Vercel with 1-click rollback and daily backup

MY TAKE

Simple that works is worth more than complex that impresses.

In practice, when an open-weight model can enter the real development cycle, the conversation moves from benchmark to operations. What matters is integrating review, deploy, and human business decisions with viable governance.
