GPT-5.4: The Advancements in Mini and Nano AI Models
GPT-5.4 has been introduced with two new, smaller AI models: the GPT-5.4 mini and the GPT-5.4 nano. These models are lighter and quicker, specifically designed to manage a high volume of requests while reducing costs. Here’s what you need to know about the innovative GPT-5.4 series models.
Features and Benchmarks of GPT-5.4 Mini and Nano
The GPT-5.4 mini showcases enhanced performance in coding, reasoning, multimodal tasks, and tool usage, advancing beyond the capabilities of the previous GPT-5 mini model. The improvements indicate that it operates at double the speed and delivers results comparable to the larger GPT-5.4 model.
Regarding benchmark performance, the GPT-5.4 mini achieved a score of 54.4%, while the GPT-5.4 registered a score of 57.7% on SWE-Bench Pro. In the OSWorld-Verified benchmarks, the mini model scored 72.1%, closely following the 75% of the larger GPT-5.4.
Specifications of GPT-5.4 Nano
The GPT-5.4 nano stands out as the most compact and economically priced version of the GPT-5.4 lineup. This model is particularly suggested for straightforward tasks such as classification, data extraction, ranking, and the utilisation of code subagents.
While it may not operate as quickly or efficiently as the GPT-5.4 mini, it surpasses the GPT-5 mini in coding and tool applications. The nano model scored 39.01% on OSWorld-Verified and 52.4% on SWE-Bench Pro, making it clear that it is not designed for internet browsing or intricate multi-step reasoning tasks. Instead, it is engineered for repetitive tasks that can run thousands of times daily within a broader AI framework.
Applications of GPT-5.4 Mini and Nano
The GPT-5.4 mini and nano models are suitable for various coding-related activities, including editing, navigating codebases, generating front-end code, and debugging, as both outperform the older GPT-5 mini models.
Additionally, the GPT-5.4 mini features abilities for reviewing large files, processing documents, and even conducting searches within codebases. Moreover, these models can handle tasks within the realms of computer and multimodal functions.
Availability of GPT-5.4 Mini and Nano
The GPT-5.4 mini is accessible through the API, Codex, and ChatGPT starting today.
Within the API, the GPT-5.4 mini provides a context window of 400,000 tokens for a variety of tasks, including text processing, image handling, web searches, file management, and computer actions.
In Codex, these models can seamlessly integrate across applications, command line interfaces, integrated development environments, and websites, adeptly managing simpler coding assignments.
For ChatGPT users, it is available for Free and Go users under the “Thinking” option.
The GPT-5.4 nano can be accessed solely via API, catering to simple, high-volume tasks at markedly low costs.
