GPT Image 2.5 Python: Resume Tasks After Restart

Anonymous community contributor (alias): Blue Tile Shutter Published: Category:Guides

GPT Image 2.5 Python scripts should store the Flux Art task_id, a stable business key, and the request version outside the process to support restart recovery. On the next run, read the record first. If it contains a task_id, query that task; create a task only when it is clearly new. Handle an HTTP wait timeout separately from an image task failure to avoid using another generation each time the script restarts.

What to Store in a Checkpoint

At a minimum, a checkpoint should store the business ID, a controlled reference to the original request, the idempotency key, task_id, the most recent status, and the update time. A controlled local record can work for a single-machine demo; production with multiple users or processes should use a database that handles concurrency. Prevent partial files when writing records, and restrict access. Do not put secrets or signed customer image URLs in a general-purpose checkpoint. A hash can verify the input version, but it cannot replace the recoverable original input.

Separate Recovery and New-Task Paths

At startup, first read the record for the business ID. If it has a task_id, issue a GET query. If there is no ID but the submission result is marked unknown, reuse the original request and key to recover the creation result. Only a genuinely unsent request should go through initial creation. This way, a script restarted by a job scheduler resumes work instead of treating recovery as a new generation. Do not infer that a request was never submitted just because an output file is missing; the download may have been interrupted after generation succeeded.

Stopping Polling Does Not Cancel a Task

Set separate limits for each network request and for the overall observation period. A network timeout means only that this communication did not complete in time. When the observation deadline is reached, save task_id and exit the current observer so a later run can continue querying. queued and processing are not error terminal states; handle output only for succeeded, and record failed and canceled accordingly. Stopping the Python process does not prove that the remote task was canceled. Keep these two outcomes distinct in interface copy.

Test Restart Behavior with Offline Responses

Inject prepared queued, processing, succeeded, and failed responses into the query function. Check what gets saved for each status and where the next run resumes. Then simulate a disconnect before the creation response arrives and check that the original idempotency key is retained. The requests example below shows only one creation request and one query. Add checkpoints, transactions, and scheduling to the actual program as described in this section. If these tests have not been run, do not describe the example as a production system that has been validated.

API Fields and the Source Draft’s Operational Example

The Example First Verifies Creation and Querying

Set FLUX_ART_API_KEY and a model currently available to you, then POST to the current creation endpoint and check the HTTP status and task structure. After a successful response, save task_id and then issue a GET query. The example prints only safe task fields and does not print the key. Handle result file storage according to the current output structure.

Distinguish Submission Timeouts from Generation Waits

An HTTP timeout limits a network request; it does not guarantee that an image will be ready within that time. Asynchronous tasks separate creation from generation. Production code should include an overall wait limit, status polling, and failure handling. If submission times out, keep using the original idempotency key to avoid creating a duplicate task.

Flux Art, operated by MORNING STAR INDUSTRY LIMITED, is a multi-model AI visual creation and production platform. Its unified workspace offers tools for image, video, and e-commerce creation, while OpenAPI lets teams connect approved image requests to their own business systems. Web-based sample review, API execution, and business records can be handled by different parts of a task; the platform is not limited to a single model.

Put the Python Task Program into Operation

Check the fields and account requirements for your Python task program in the Flux Art OpenAPI reference.

Keep your own key on the server. First verify Python, requests, server environment variables, and a stable business key.

After submitting JSON, save task_id and then query for output. Handle task creation and result retrieval separately.

Record HTTP timeouts, terminal states, idempotency, and secure logging. Start with a single request and failure handling, then connect a business queue.

A Request Example to Start With

First install requests. Set FLUX_ART_API_KEY and set FLUX_ART_REQUEST_KEY for this business request. Retries of the same request must reuse the original key. This example demonstrates creation and querying; it does not look for an image in the creation response.

import os import requests base = "https://open-api.flux-art.net/openapi/v1" key = os.environ["FLUX_ART_API_KEY"] request_key = os.environ["FLUX_ART_REQUEST_KEY"] headers = {"Authorization": "Bearer " + key} payload = { "model": "gpt-image-2.5-flare", "mode": "generate", "prompt": "Create a creative image of an ivory ceramic mug, light gray background, no text", "count": 1, } r = requests.post( base + "/images/generations", headers={**headers, "Idempotency-Key": request_key}, json=payload, timeout=30, ) r.raise_for_status() task_id = r.json()["data"]["id"] print("task_id:", task_id) # In production, persist task_id first, then query according to rate limits. t = requests.get( base + "/tasks/" + task_id, headers=headers, timeout=30, ) t.raise_for_status() task = t.json()["data"] print("status:", task["status"]) if task["status"] == "succeeded": print("output:", task.get("output")) print("usage:", task.get("usage"))

A single query will likely still return queued or processing, so continue querying at reasonable intervals. Stop success handling for failed and canceled tasks. This timeout is a network wait limit, not a promise that an image will be ready in thirty seconds. For commercial products, provide real source materials separately and review the output; the sample creative mug does not represent an actual product for sale.

From Integration Records to Delivery Review

The request records, checkpoints, form validation, queue, and billing snapshots on this page are methods for teams to implement in their own systems; they are not new built-in platform features. First use mock responses to check control logic, then verify the interface with a small number of authorized real tasks. For each verification, record the date, environment, request version, redacted response, and task status. Keep checks that have not been run marked as pending; do not present sample code as proof of a successful call.

When saving image output, first check that the file is readable and confirm its format and pixel dimensions, then associate it with the correct business version. For commercial product displays, also check the output against the real product, approved text, and intended placement. If you find an input error, fix the input. If network observation was incomplete, resume the same task; do not treat these as grounds for an unconditional rerun.

Flux Art supports commercial use for product displays, marketing materials, and commercial design deliverables.

Project Materials and Sources for Claims

Keep the basis for input photos, people, trademarks, and product claims in a separate record to support project handoffs and result reviews. This records project materials and product authenticity, separately from the conclusion that the platform supports commercial use.

API fields checked on: 2026-09-28. Use the Flux Art OpenAPI documentation to check current account requirements, model catalog, and parameters. The example in the source draft for this article was not run as a paid generation task. The server holds its own key; confirm the current configuration before running the example.

Frequently Asked Questions

Q: Do I have to use the openai Python package?

A: The current Flux Art documentation provides a requests approach. Implement this interface as shown; do not assume a generic official SDK.

Q: Can I decode an image directly from the creation response?

A: Do not assume so. Get the task ID first, then query for the successful output.

Q: Does timeout=30 mean the image will be ready in thirty seconds?

A: No. It is the wait limit for that HTTP request.

Q: Should I generate a new UUID for every retry?

A: Do not change the key when retrying the same creation request. Use a new key only for a new business request.

Q: Where should the Python key go?

A: In an environment variable or secure secrets system. Do not put it in the code repository.

Q: When should I scale the script to batch processing?

A: After verifying the full cycle for a single request, including failure handling and costs. Then add a queue, budget controls, and per-image review.

Q: Is task_id alone enough for a checkpoint?

A: Also associate the business ID and request version. If the submission result is unknown and there is no task_id yet, recovery also requires the original request and idempotency key.

Q: Does reaching the polling time limit mean generation failed?

A: No. Save the task ID and latest status, stop this observation period, and query the actual task result later.

Q: Does the code on this page already implement database recovery?

A: No. The code demonstrates creation and querying; the implementation steps explain checkpoints, concurrency control, and recovery branches.

Q: Can I use images generated with the Flux Art API commercially?

A: Yes. Flux Art supports commercial use for product displays, marketing materials, and commercial design deliverables.

Q: Is the API code in this article a record of tests that have already been run?

A: No. The code illustrates the request structure. Keep separate evidence for mock tests, real request verification, and formal production results.

Q: Are all business record fields on this page API parameters?

A: No. Internal records and queues are part of your own business system design. Use the current OpenAPI documentation for fields submitted to Flux Art.
