Our take
GPT-4.1 Nano is 1.5x cheaper for a typical chat. GPT-4.1 Nano scores higher on the Artificial Analysis Intelligence Index (7.8 vs 6.7). GPT-4.1 Nano has the larger context window (1.05M vs 128K tokens). The right pick depends on your workload, so the quickest way to settle it is to send the same prompt to both and compare.
FAQ
Frequently asked questions
Is GPT-4.1 Nano or GPT-4o-mini cheaper?
GPT-4.1 Nano is cheaper for a typical chat (2K input tokens and 500 output tokens). GPT-4.1 Nano costs $0.10 per 1M input tokens and $0.40 per 1M output tokens, while GPT-4o-mini costs $0.15 per 1M input tokens and $0.60 per 1M output tokens.
Which has a bigger context window, GPT-4.1 Nano or GPT-4o-mini?
GPT-4.1 Nano supports up to 1.05M tokens of context, compared with 128K for GPT-4o-mini.
Is GPT-4.1 Nano smarter than GPT-4o-mini?
On the Artificial Analysis Intelligence Index, GPT-4.1 Nano scores 7.8 and GPT-4o-mini scores 6.7, putting GPT-4.1 Nano ahead. Benchmarks don't capture everything, so the best test is running your own prompts through both.
Can I use GPT-4.1 Nano and GPT-4o-mini at the same time?
Yes. Shortcut Chat sends one prompt to multiple models at once, so you can see GPT-4.1 Nano and GPT-4o-mini answer side by side and keep the better response.
Why choose? Ask both.
Send one prompt to GPT-4.1 Nano and GPT-4o-mini at the same time. Compare the answers side by side and keep the best one.
