OpenAI models are getting more stable, and a Reddit user says GPT-5.5 now looks highly reliable
ionutvi · reddit · 2026-07-27
A Reddit user says OpenAI’s latest models feel much more stable in day-to-day use: fewer mid-task collapses, more repeatable outputs, and better consistency across prompts.
The post cites AI Stupid Level, which continuously reruns practical tests instead of relying on a one-off benchmark snapshot, and says GPT-5.5 currently ranks among the most reliable models. The author also discloses that they built the benchmark, so the thread mixes user experience with a self-reported evaluation signal.
