GPT-5.5 (Non-reasoning)
Analysis Summary
GPT-5.5 (Non-reasoning) is a non-thinking variant from OpenAI's GPT-5.5 family, with a coding index of 56.5 and agentic index of 59.3. Its terminal benchmark score of 0.492 and tau2 of 0.693 suggest reliable performance on structured coding and tool-use tasks, while its instruction-following and long-context retrieval scores are competitive.
At $5 input and $30 output per million tokens, it sits at a mid-range price point for the capability it delivers. It is well-suited to software development assistance, agentic pipelines, and content workflows where the full reasoning overhead of the thinking variants is unnecessary.
For teams wanting GPT-5.5 capability without the latency and cost of extended reasoning, this variant offers a practical balance for production coding and automation workloads.
