GPT‑4.1 mini brings GPT‑4o’s reasoning strength and multimodal capabilities into a smaller, lower‑cost form that runs at about 80 % lower cost and delivers faster responses. It accepts both text and imagery and can reliably process large documents or full conversation transcripts. Drop in a meeting log or product catalog and get a polished summary, clear marketing copy, or structured breakdown. You can tune how much context it uses to trade off speed for precision only where it matters.
