GPT-5.5 (low)
Analysis Summary
GPT-5.5 low is an OpenAI variant with an intelligence index of 44.5 and a coding index of 60.9. It combines strong reasoning, coding, long-context, and terminal performance with good task success. Its instruction-following and agentic results are below the medium and high variants, creating a clearer boundary around autonomous or highly constrained work.
The model is well suited to supervised coding assistance, content drafting, SEO production, analysis, and structured transformations. It can handle substantial reasoning without requiring the highest-compute setting, but the supplied pricing is the same as the other listed GPT-5.5 variants, which reduces its value advantage in this dataset.
Choose it for routine professional workloads where quality matters and workflows include review or validation. Escalate complex agentic tasks to a stronger variant.
