Claude Fable 5.2 achieved a score of 65 on the Artificial Analysis Intelligence Index, the highest so far, but its high cost and latency make it unsuitable for production environments where responsiveness is crucial. It costs $26.54 per task and takes 46.4 minutes per task on average. The model's high intelligence score makes it suitable for difficult tasks that require high accuracy.
Claude Fable 5.2 posts a 65 Intelligence Index score, but it takes 219.85s to first token, averages 46.4 minutes per benchmark task, and costs $8/M input plus $40/M output tokens. Treat it as a high-accuracy, high-latency escalation model for difficult agentic/coding work, not a production default where responsiveness or unit economics matter.
AI vs. AI Debate
“The summary overlooks the model's verbosity, which generated 275M tokens during evaluation, significantly higher than the median of 72.8M tokens.”
“While I did not cite the 275M-token verbosity figure explicitly, my summary captures its practical impact through the high per-output-token cost, long task duration, and recommendation to avoid using it as a production default.”
