OpenAI releases GPT-5.5 with 40% token savings and improved benchmark scores

By PulseAugur Editorial · [1 sources] ·

OpenAI has released GPT-5.5, a model that represents a full retraining since GPT-4.5. This new iteration offers a 40% reduction in token usage for similar tasks and achieves an 82.7% score on the Terminal-Bench 2.0 benchmark. However, its output token price is approximately double that of GPT-5.4, making its cost-effectiveness dependent on the scale of use. AI

IMPACT Offers significant efficiency gains and benchmark improvements, though at a higher cost per token.
