A timeout is a limit on how long an operation should wait. Cancellation is a way to tell an operation that its result is no longer needed. For example, an interactive application may abandon a request because a user navigated away, cancelled a task, or no longer needs the generated response. A background process may also have a total deadline that should apply to the whole operation rather than just one network attempt. The OpenAI JavaScript SDK supports passing an AbortSignal through the request options. Here is a practical example. Node.js provides AbortController, which exposes a signal that can be used to cancel compatible asynchronous operations. The OpenAI JavaScript SDK accepts the signal through the request options object. import OpenAI from "openai"; const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY, }); const controller = new AbortController(); const deadline = setTimeout(() => { controller.abort(); }, 15_000); try { const response = await client.responses.create( { model: "YOUR_MODEL_ID", input: "Explain why request cancellation matters in API clients.", }, { signal: controller.signal, } ); console.log(response.output_text); } catch (error) { if (controller.signal.aborted) { console.error("Request cancelled or overall deadline reached."); } else { throw error; } } finally { clearTimeout(deadline); } Replace YOUR_MODEL_ID with a model available to your project. The example also requires a valid API key in OPENAI_API_KEY. The finally block clears the timer whether the request succeeds, fails, or is cancelled. SDK reference: https://github.com/openai/openai-node/blob/main/docs/configuration.md The example starts a 15-second timer that aborts the operation. This is useful when an application needs a total elapsed-time limit. The SDK also offers its own request timeout setting. Those settings should not be confused. A configured SDK timeout governs an individual request attempt. Since the SDK can retry certain failures, the total elapsed time can exceed a single attempt's timeout. An application-level AbortSignal can provide a cancellation boundary around the operation when the overall deadline matters. Choose the approach according to your needs. You may want an SDK timeout, an external cancellation signal, or both. The catch block checks whether the controller was aborted. If it was, the application can report that the operation was cancelled or its deadline was reached. Otherwise, the error is propagated. In a real application, you may want to distinguish user cancellation from deadline expiry by recording which event triggered the abort. Avoid silently treating every exception as cancellation. Authentication failures, invalid requests, rate limits, and provider errors still need appropriate handling. For a streamed request, pass the signal through the same request-options mechanism: const controller = new AbortController(); const stream = await client.responses.create( { model: "YOUR_MODEL_ID", input: "Explain asynchronous iteration.", stream: true, }, { signal: controller.signal, } ); for await (const event of stream) { if (event.type === "response.output_text.delta") { process.stdout.write(event.delta); } } If the application needs a deadline or user-cancellation action, it can call controller.abort() while the stream is being consumed. The consuming code should handle the resulting cancellation or error path. A web application should also connect cancellation to its own lifecycle—for example, stopping work when a result is no longer needed. Leaving timers running: Always clean up a manually created timer in a finally block. Treating every exception as cancellation: Check the cancellation signal and preserve other errors for appropriate handling. Assuming the timeout covers every retry automatically: Understand the difference between an attempt-level timeout and an overall deadline. Forgetting the UI or caller: Cancelling the network request is only part of the feature. The application must also stop waiting, update its state, and prevent stale results from replacing a newer result. Assuming cancellation proves that no work occurred: A request may already have reached the server before the client cancels it. Cancellation should not be treated as proof that no processing or cost occurred. Cancellation is an important part of an API client's contract. It lets applications stop waiting for work whose result is no longer useful and gives them a practical way to enforce operation deadlines. Use AbortSignal deliberately, clean up timers and application state, and test the cancellation path separately from ordinary success and failure behavior.
