SWE's hot take: frontier models' raw intelligence hasn't improved nearly as much as hype suggests

Reasonable_Goat · reddit · 2026-11-15

A Reddit engineer argues LLMs got far more useful but their "raw intelligence" improved less than headlines suggest. Three observations: upgrading frontier models rarely improved a tuned production harness (failures trace to context engineering and tools); the same model varies widely across harnesses in complex codebases; capable local models suggest efficient problem-solving needs fewer parameters than assumed. He attributes much of the last 12-24 months' progress to cumulative model gains plus better harnesses, and suspects hype and doom narratives are co-fueled by upcoming AI IPOs.
