About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

GPT-5.4 nano is OpenAI’s compact GPT-5.4-class model for simple, high-volume tasks. The manufacturer highlights classification, data extraction, ranking and supporting subagent work. It accepts text and images and produces text. This gives nano a focused role in a larger process: complete a defined operation and return the information the next step needs.

For classification, provide the allowed categories, the rule that separates them and the expected result format. An illustrative task is identifying the topic of a request and the facts that justify the category. Include examples when they clarify a difficult boundary, and state how to represent a request that does not fit the available categories. A useful result is the category plus a brief justification tied to the supplied material.

For extraction, specify the fields and their definitions rather than asking for every potentially interesting detail. You can supply written material or an image of a page and identify the values required. Preserve names and units that affect the meaning, and distinguish a missing field from a value inferred from surrounding text. For ranking, supply the candidates and the criterion, then request the ordered list with the relevant evidence for each position.

OpenAI’s GPT-5.4 nano specification lists a 400,000-token context window, a maximum input of 272,000 tokens and a maximum output of 128,000 tokens, with a knowledge cutoff of August 31, 2025. It supports none, low, medium, high and xhigh reasoning effort; none is the default. The selected effort and requested answer length should fit the task. When reasoning is used, allow space for analysis as well as the visible result.

The producer documents Responses, Chat Completions and Batch interfaces, together with streaming, Structured Outputs, function calling, web and file search, file inputs, image input and prompt caching. Its tool set includes image generation, code interpretation, hosted shell and patch operations, skills and MCP connections. An application exposes its operations and returns their actual results. A structured response describes the form of the output; a function request describes an action for a tool to perform.

In a multi-stage workflow, give nano a bounded supporting task and a clear completion criterion. For example, extract the required facts from several messages, then pass those facts to the next stage for a broader decision. Check the returned fields against the original input and refine the rule when a category boundary is unclear. A concise category, set of values, ranked list or proposed tool arguments is a useful final artifact when its purpose and source evidence remain explicit.
