GPT-4.1 vs GPT-5 mini

Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.

GPT-4.1

OpenAI · Apr 2025

A non-reasoning workhorse with a 1M-token context window, still popular for predictable-latency production APIs.

GPT-5 mini

OpenAI · Aug 2025

A fast, cheap distillation of GPT-5 for high-volume workloads — one fifth of the flagship's price with most of its everyday capability.

The verdict

GPT-5 mini wins 2 of the 2 benchmarks these models share, against 0 for GPT-4.1. On price the gap is dramatic: GPT-5 mini works out roughly 5.1x cheaper per blended million tokens. GPT-4.1 also takes 1M of context versus 400K for GPT-5 mini.
