GPT-5.5 Price Doubles, But Efficiency Gains Limit User Cost Increase

While GPT-5.5 carries a 2x official price increase, real-world cost analysis shows actual expenses rise only 49-92% for users—driven by the model's increased efficiency in generating shorter completions. However, this benefit applies primarily to longer prompts; users with shorter request patterns face steeper cost increases, making individual cost-benefit reassessment critical for API-dependent teams.
