GPT-5.5 (low)
Analysis Summary
GPT-5.5 (low) is the minimum reasoning-budget variant of OpenAI's GPT-5.5 family, with an intelligence index of 43.5, coding index of 60.9, and agentic index of 68.1. Its instruction-following score of 0.644, long-context retrieval of 0.720, and terminal benchmark of 0.523 are strong across the board, and its tau2 of 0.839 indicates reliable structured task completion.
For businesses, this variant offers a compelling balance: near-frontier capability at the same $5/$30 per million token price as the medium and non-reasoning variants, with lower latency due to reduced reasoning overhead. It suits coding assistance, agentic workflows, and content tasks where speed matters more than maximum reasoning depth.
Teams running high-throughput pipelines or latency-sensitive applications should consider this variant as a primary option, escalating to the medium or high variants only when task complexity demands it.
