Editorial Analysis
Profile. GPT-5.4 (xhigh) is a premium-tier model from OpenAI at $15.00/M output tokens. Benchmark scores (e.g. Coding Index 71.1) 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-5.4 (xhigh) reports 131 tok/s output speed and 144080ms time-to-first-token. Output speed is in the normal range — most chat and completion applications will be token-bound, not streaming-bound.
Cost model. For a workload of 1M input tokens + 100K output tokens, GPT-5.4 (xhigh) costs $4.00 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.
