GPT-5.4 Nano vs GPT-4o Mini: which has lower API cost for classification?
Compare verified pricing and model limits for replacing GPT-4o Mini with a lower-cost OpenAI routing tier. The cost example uses a classification and routing workload and does not assume equal model quality.
Direct cost answer: GPT-4o mini is estimated at $76.50 per month and gpt-5.4-nano at $120.00 for 700 input tokens, 80 output tokens, and 500,000 monthly requests. GPT-4o mini is $43.50 lower under these assumptions. This does not identify a quality winner.

Questions to answer before choosing
- Does Nano meet the required classification threshold?
- How many ambiguous cases still need GPT-4o Mini?
- Will shorter outputs preserve the expected cost advantage?
What this estimate leaves out
Quality and latency are not assumed equal across models; validate labels on a representative evaluation set.
Latency, reliability, output quality, retries, regional processing, and provider-specific tool charges can change the practical decision.
