Claude Opus 5 Token Inflation Slows Task Completion

Although Claude Opus 5 boasts a generation speed of 57 tokens per second—faster on paper than Fable 5—users report that it feels painfully slow for routine tasks. The core cause is token inflation rather than generation latency; the model generates far more intermediate tokens and detailed steps, particularly under high-effort configurations, leading to longer end-to-end task completion times.

// ANALYSIS

Raw token generation speed is a misleading metric for reasoning models; total task completion latency matters far more than tokens per second.

–Excessive chain-of-thought and step-by-step reasoning cause massive token inflation on simple prompts.
–High effort modes exacerbate latency by encouraging unnecessary intermediate steps.
–AI benchmarking needs to shift focus from raw output throughput to time-to-result efficiency.
