Cost Efficiency Analysis - Grok 4.5 demonstrates superior cost-effectiveness, requiring only $2.49 per task compared to $11.80 for Fable 5 and $5.07 for GPT-5.5 [1] - The cost advantage is primarily attributed to lower token pricing and optimized model architecture [1] Operational Performance - Grok 4.5 utilizes an average of 1.9 million tokens per task, significantly lower than the 7.2 million tokens required by Fable 5 and 6.2 million tokens by GPT-5.5 [1] - Reduced token consumption serves as a key driver for the enhanced efficiency of Grok 4.5 relative to industry peers [1]
