OpenAI has launched GPT-4o mini, a powerful and affordable AI model designed to make artificial intelligence more accessible. Priced at just 15 cents per million input tokens and 60 cents per million output tokens, GPT-4o mini offers a cost-effective alternative to models like GPT-3.5 Turbo.

According to OpenAI’s blog, GPT-4o mini excels in performance, scoring 82% on the MMLU benchmark and surpassing GPT-4.1 on the LMSYS leaderboard for chat preferences. It handles a variety of tasks with low cost and fast response times, making it ideal for applications requiring multiple model calls, large volumes of context, or real-time text interactions such as customer support chatbots.

The model currently supports text and vision inputs, with plans to include image, video, and audio inputs and outputs in the future. GPT-4o mini has a context window of 128K tokens and supports up to 16K output tokens per request, with knowledge updated until October 2023. Its improved tokenizer enhances the cost-effectiveness of handling non-English text.

GPT-4o mini also shines in academic and practical applications, outperforming other small models in reasoning, math, and coding tasks. For example, it scored 87% in mathematical reasoning and 87.2% in coding performance on benchmarks like MGSM and HumanEval, respectively.

Safety is a key feature of GPT-4o mini, with robust measures such as filtering harmful content during pre-training and using reinforcement learning with human feedback (RLHF) to align the model’s behavior with safety policies. Over 70 external experts have tested the model to identify and mitigate potential risks, ensuring its reliability and safety.

GPT-4o mini is now available through the Assistants API, Chat Completions API, and Batch API. It will be accessible to Free, Plus, and Team users on ChatGPT starting today, with enterprise users gaining access next week. OpenAI also plans to introduce fine-tuning capabilities for GPT-4o mini soon.

OpenAI continues to aim at reducing costs while enhancing AI capabilities. The introduction of GPT-4o mini is a step toward integrating powerful AI into everyday applications, making advanced intelligence more affordable and accessible for developers and users alike.
