FAQs
Why use Nano over GPT-4o Mini?
Nano hits $0.05/$0.40 per million tokens—significantly lower than even GPT-4o Mini. Perfect for short prompts and deterministic flows.
Does Nano share the 270K context tier?
OpenAI prices it under the same <270K bucket, so TokenTally models a 270K cap for completeness.
Any limitations?
Lower reasoning depth compared to other GPT-5 models. Use it for templated tasks and budget-critical automations.
