OpenAI, a leader in AI software and backed by Microsoft, announced the launch of GPT-4o mini on Thursday.

This new small AI model is designed to be more affordable and energy-efficient.

Priced at 15 cents per million input tokens and 60 cents per million output tokens, GPT-4o mini is over 60% cheaper than its predecessor, GPT-3.5 Turbo.

The model outperformed GPT-4 in chat preferences and scored 82% on the Massive Multitask Language Understanding (MMLU) benchmark, surpassing Google's Gemini Flash at 77.9% and Anthropic's Claude Haiku at 73.8%.

The smaller model requires less computational power, making it a budget-friendly option for businesses.
