GPT-4 Turbo vs GPT-4o-mini
GPT-4 Turbo leads GPT-4o-mini on the Artificial Analysis Intelligence Index, 7.0 to 6.7, and GPT-4o-mini costs 50.0x less per output token ($0.60 vs $30.00 per million). Updated October 22, 2026; 10 benchmarks have a result for both.
GPT-4 Turbo or GPT-4o-mini: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4 Turbo for work measured by Humanity's Last Exam (Artificial Analysis run) or MMLU, where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
GPT-4o-mini costs less
