GEMINI 4 ARGON: 115 REGRESSIONS IN FOUR HOURS, CODER CLAIMS — THEN FOUR MORE HOURS TO FIX THEM

A developer posting to r/GeminiAI on October 15 described four hours of Argon High coding work that introduced 115 regressions caught by deterministic tests, followed by another four hours repairing the damage. The author also said Argon took roughly four times as long as Opus 5.5 High on the compared work. The post did not publish the full tasks, logs, test denominators or matched conditions, so the figures remain the reporter's claims.

The report landed alongside other early complaints, including Theo Browne's claim that Argon invented how his code worked in most tests. Google's own counter-example was an overnight run on a large Python codebase where two of six proposed optimisations were accepted after review. Without matched tasks across models, the public reports establish a backlash and conflicting experiences, not a measured average for Argon's coding quality.
