## Overview

GPT-4o mini is OpenAI's small model for fast, lightweight and focused tasks. It accepts text and image input, supports tool calling and structured output, and returns text. It has a context window of 128,000 tokens and was released on July 18, 2024.

GPT-4o mini has a context window of 128,000 tokens and can generate up to 16,384 output tokens. It accepts text and image input and returns text output. Its knowledge cutoff is October 1, 2023, and it was released on July 18, 2024.

## Capabilities

GPT-4o mini supports tool calling, structured output and image input, and it returns text. It can generate up to 16,384 output tokens per request.

Its knowledge cutoff is October 1, 2023. Cached input reads have their own lower price, which helps when many requests share the same long prompt.

## Pricing

GPT-4o mini is billed per token: $0.15 per 1M input tokens and $0.60 per 1M output tokens. Cached input reads cost $0.075 per 1M tokens. GPT-4o mini is available through RealRelay's OpenAI-compatible API.

## Use cases

Use GPT-4o mini for high-volume, focused jobs such as short answers, classification-style labeling of text, or extracting fields from an image into structured output.

Its tool calling suits lightweight assistants that call a few functions per request, where fast, low-priced replies matter more than long reasoning. Up to 16,384 output tokens are available per reply.
