GPT-4o Mini
Chat-20%openai/gpt-4o-miniGPT-4o Mini is OpenAI's small, cost-efficient model from the GPT-4o generation, released on 2024-07-18, priced 60% below GPT-3.5 Turbo while scoring 82% on MMLU. It targets high-volume tasks that still need solid language understanding and generation, and supports vision, tool use, and prompt caching. Context: 128K tokens, output: 16K. At $0.15/M input tokens and $0.60/M output tokens it remains one of the cheapest ways to run simple, high-throughput workloads, though newer small models offer stronger reasoning. Accessible via the OpenAI-compatible protocol.
