The Economics of Scale: Real Cost Calculations

Translating per-token pricing into real-world costs reveals the transformative potential of o3's new pricing structure. Consider a typical enterprise chatbot handling customer queries: processing 1 million daily interactions averaging 500 tokens each would cost approximately 1,000perdayusingstandardo3,orjust1,000 per day using standard o3, or just 110 with o3-mini. This represents a dramatic shift from previous pricing models that would have made such applications prohibitively expensive.

For document processing workflows, the economics become even more compelling. A legal firm analyzing 10,000 contracts monthly, with each contract averaging 20,000 tokens, would face input costs of just 400usingstandardo3.Addingtypicaloutputgenerationof5,000tokenspercontractforsummariesandinsightsbringsthetotaltoapproximately400 using standard o3. Adding typical output generation of 5,000 tokens per contract for summaries and insights brings the total to approximately 1,600 monthly—less than the cost of a single junior associate's daily rate.

The introduction of Flex pricing tiers adds another dimension to cost optimization. o3 Flex, priced at 0.005per1Kinputtokensand0.005 per 1K input tokens and 0.020 per 1K output tokens, offers a 50% discount for tasks that can tolerate longer processing times. Organizations running overnight batch analytics or generating monthly reports can leverage Flex pricing to achieve substantial savings without impacting user experience. One financial services firm reported saving $45,000 monthly by shifting non-urgent processing to Flex tiers.
