GPT-5.5 (Non-reasoning)
Analysis Summary
GPT-5.5 Non-reasoning has a low overall intelligence result alongside a strong coding result and moderate agentic performance. Its long-context result is useful, while instruction following is a relative weakness in this profile. Pricing is listed at $5 per million input tokens and $30 per million output tokens, making it an expensive choice for routine workloads compared with lower-cost options.
The model may fit developer workflows focused on code generation or editing where a human can review the output. It is less compelling for client-facing content or complex instructions, where the weaker instruction-following result raises the risk of inconsistent execution. The entry does not list tool use or function calling, so an integrated agent role is not established by the supplied data.
Use it selectively for coding tasks that benefit from its measured strength, and compare its output quality with a stronger reasoning variant before committing to broader workflows. Keep routine traffic on a less costly model.
