GPT-4o mini vs GPT-5 nano
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
GPT-4o mini
OpenAI · Jul 2024
The 2024 budget classic that defined the cheap-LLM tier; GPT-5 nano and mini have since taken its crown.
GPT-5 nano
OpenAI · Aug 2025
OpenAI's cheapest model — $0.05 per million input tokens — for latency-critical routing, autocomplete and bulk tagging.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. GPT-5 nano is about 1.9x cheaper per blended million tokens (3:1 input:output mix). GPT-5 nano also takes 400K of context versus 128K for GPT-4o mini.
