The Two-Speed Roadmap: Planning AI Features When the Model Floor Moves Every Quarter
There is a specific kind of regret that only happens on AI teams. You spend a quarter building an elaborate workaround — a multi-step prompt chain, a custom reranker, a hand-tuned tool-routing layer — and ship it. It works. Then six weeks later a new model drops, does the whole thing natively in one call, and your quarter of work is now dead weight you have to rip out. The feature didn't fail. The floor moved.
This is the structural problem with planning AI features in 2026: the substrate you're building on is improving faster than your release cycle. From 2023 into mid-2025, frontier labs shipped on a roughly six-month cadence. By Q1 2026 that compressed to substantive releases roughly every four weeks, with stretches where five labs shipped inside a thirteen-day window. The thing you're standing on moves under you between planning and launch.
