GPT-5.4 Mini
Overview
GPT-5.4 Mini is a language model developed by OpenAI, designed to deliver the capabilities of the GPT-5.4 series in a more efficient and cost-effective form. It features a context window of 400,000 tokens and supports both text and image inputs, making it suitable for tasks that require processing large amounts of information. The model is optimized for high-throughput workloads, offering faster response times compared to its predecessors. In terms of performance, GPT-5.4 Mini demonstrates strong capabilities across various domains. It excels in coding tasks, handling codebase navigation, front-end generation, and debugging with low latency. The model also performs well in multimodal tasks, particularly those related to computer use, such as interpreting screenshots of dense user interfaces. Additionally, GPT-5.4 Mini is effective in systems that combine models of different sizes, serving as subagents that handle narrower subtasks in parallel. Its pricing structure is competitive, with input tokens priced at $0.75 per million and output tokens at $4.50 per million, positioning it as a cost-effective solution for developers seeking efficiency without compromising performance. GPT-5.4 Mini is available through OpenAI's API, Codex, and ChatGPT platforms. In Codex, it consumes only 30% of the GPT-5.4 quota, allowing developers to handle simpler coding tasks at approximately one-third the cost. In ChatGPT, GPT-5.4 Mini is accessible to Free and Go users via the "Thinking" feature in the menu. This accessibility, combined with its performance and pricing, makes GPT-5.4 Mini a compelling choice for a wide range of applications.
