AI model usage policy deviates from actual implementation, author finds

The author details a discrepancy between their intended AI model usage policy and the actual models employed, discovering 96 deviations out of 425 decisions. These deviations, costing over $1,200, primarily occurred when the system was not actively processing the main thread of tasks. The author emphasizes the importance of revising policies based on observed behavior, using the example of a policy correction for research tasks that initially misclassified them as low-cost. Furthermore, the author presents evidence of the trace log's reliability by analyzing the usage patterns of Claude Fable 5, noting that its availability and subsequent drainage of in-progress tasks were accurately reflected in the logs without explicit instruction. AI
