Editorial Analysis
Profile. GPT-5.5 (low) is a premium-tier model from OpenAI at $30.00/M output tokens. Benchmark scores (e.g. Coding Index 60.9) suggest it targets workloads where correctness matters more than cost — long-running agents, code generation at scale, and complex multi-step reasoning.
Latency. On latency, GPT-5.5 (low) reports 72 tok/s output speed and 2000ms time-to-first-token. Output speed is on the slower end; for real-time chat consider pairing with a streaming front-end or routing latency-sensitive requests to a faster model.
Cost model. For a workload of 1M input tokens + 100K output tokens, GPT-5.5 (low) costs $8.00 per million input-equivalent requests. Multiply by your monthly request volume to project the bill, and compare against the speed/correctness profile above to decide if the trade-off is worth it for your workload.
