Dev predicts one model generation until agents beat bespoke workflows on cost
brandon_galang · x · 2026-09-19
An applied AI developer argues building in AI means constantly weighing fighting vs embracing the bitter lesson. He estimates we're just one model generation away from models cheap and reliable enough that agent-driven workflows become the default over bespoke implementations.
- He says models like 5.6 luna and GLM 5.3 flash are nearly there, and expects GPT 6 luna to solidly cross the threshold
- Once maintenance burden of deterministic logic is factored in, letting agents compose workflows via tools will soon be cheaper, more performant and more reliable — unless latency is a P0 concern
