Report #39571

[cost\_intel] How do I navigate the latency-vs-reasoning-effort tradeoff with o3-mini specifically?

Use o3-mini-low for <2s latency with moderate reasoning, o3-mini-medium for balanced 5-10s tasks, and o3-mini-high only for offline batch processing; never use high effort for user-facing sync operations.

Journey Context:
o3-mini introduces three effort levels \(low, medium, high\) that directly map to reasoning tokens and latency. Unlike previous models, o3-mini-high can exceed 30 seconds on complex prompts, which is acceptable for data enrichment pipelines but fatal for live UX. The 'medium' setting typically adds 3-5x latency over GPT-4o but provides 70% of o1's reasoning capability, making it the sweet spot for 'intelligent autocomplete' or 'suggested edits'. Low effort is competitive with GPT-4o on simple reasoning but cheaper. The common error is treating effort levels as 'quality sliders' for all contexts rather than 'latency compromisers'.
