Three developments this week signal where AI is actually heading.
Opus 4.5 hit a 50% time horizon of ~5 hours on METR's autonomous tasks. The previous best was 59 minutes. Boris Cherny shipped 259 PRs to Claude Code last month, all written by Claude Code itself. He didn't open an IDE.
The models are working. In production. At scale.
A huge change is happening in software development
So where's the value shifting?
Facebook paying $2B for Manus AI, a company that builds agent infrastructure, not models . tells you everything.
As models commoditize, scaffolding becomes the moat. The orchestration layer. The reliability engineering. The human AI interface design.
Manus hit $125M ARR in 8 months by wrapping frontier models in good software.
The question isn't "which model wins." It's who builds the best systems on top of whichever model wins.
Start upskilling on how to use these tools, or risk getting left behind.
The shift is happening.
