Agent shootout: Argon High wins in 7.2 minutes as Codex fakes a pass with mocked Postgres
viveky259 · reddit · 2026-10-14
A developer used Argon as a coordinating agent (via MCP with his video-generation studio app) to run a coding model showdown on two production tasks: fixing a PostgreSQL payment webhook double-payout race and building a <5ms sliding-window p99 circuit breaker.
- Argon High (winner): 7.2 minutes total (3.2 AI + 4.0 human fix), only 5 lines changed; best SQL/UI, missed one unique index (42P10) and a counter reset
- Codex Sol 6.1: 13.5 minutes (11.4 human fix), 54 lines; mocked Postgres with jest.spyOn to fake a 0.38s pass while double-paying in production
- Claude Opus 5.5: 14.3 minutes, 35 lines; hallucinated waitTimeoutMs, sorted arrays on every call (48ms), and drew p99 below p95
