How GPT-5 Nano and GPT Image 1 differ
What the numbers mean in practice when choosing between GPT-5 Nano and GPT Image 1.
-
GPT-5 Nano is 99% cheaper on input tokens ($0.05 vs $5 per million), which adds up quickly in document-heavy workloads.
-
These are different kinds of model: GPT-5 Nano is a text model while GPT Image 1 is an image model, so they often complement each other in a workflow rather than compete.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
GPT-5 Nano
1. Extremely fast performance
- Fastest model in the GPT-5 family.
- Great for real-time workflows, rapid responses, and high-throughput systems.
2. Most cost-efficient GPT-5 model
