DeepSWE: More and cheaper intelligence from maxed GPT 5.5 than maxed Opus 4.8

DeepSWE has demonstrated that a fully optimized GPT 5.5 model can generate more intelligence at a lower cost than a maxed-out Opus 4.8, marking a significant efficiency breakthrough in AI performance. The comparison shows that scaling up GPT 5.5 to its maximum configuration outperforms the top-tier Opus 4.8 while reducing computational expenses. This development could reshape AI deployment strategies by prioritizing cost-effective intelligence over raw model size.
