GPT-4o mini vs GPT-5
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
70.7OpenAI · Aug 2025
OpenAI's August 2025 unified flagship that merged the GPT and o-series reasoning lines into one model with selectable effort.
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. On price the gap is dramatic: GPT-4o mini works out roughly 13x cheaper per blended million tokens. GPT-5 also takes 400K of context versus 128K for GPT-4o mini.
