GPT-4.1 Mini
openai/gpt-4.1-miniGPT-4.1 mini is the smaller, faster tier of OpenAI's GPT-4.1 series, released in April 2025 as a non-reasoning model that accepts text and images and returns text. OpenAI describes it as strong at instruction following and tool calling, with the same 1M-token context window as GPT-4.1 and lower latency. It suits interactive apps, chat and agent tool calls where responsiveness matters more than the extra depth of full GPT-4.1.
