GPT-4o-mini (batch) offers 17% better value per quality point. At 1M tokens/day, you'd spend $5.63/month with GPT-4o-mini (batch) vs $6.75/month with GPT-5 Nano - a $1.12 monthly difference.

Latency & Speed
GPT-4o-mini (batch)Faster
Speed score0/100
GPT-5 Nano
Speed score0/100

Both models have comparable response speeds. For most applications, the latency difference is negligible.

When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.
