Dev: The Smartest Model Isn't the Best at Writing Simple, Mergeable Code

timigod · x · 2026-09-18

Developer timigod observes that OpenAI's new model Astra shows "spiky/weird" coding behavior, and speculates it stems from OpenAI optimizing for general intelligence across a broad task range—coding, 3D, computer use, math—rather than tuning specifically for everyday software engineering.

From his hands-on experience, we're in a weird window: the model that feels most generally intelligent isn't the best at writing simple, straightforward, mergeable code. Coding-focused models like Cursor Grok are currently better at that. He still thinks OpenAI's generalist bet is the right long-term call.
