Quick answer
OpenAI's latest image generation model (GPT-Image-2.5 Sunburst) is currently available for free direct access on Arena.ai (under arena.ai/image/direct) during a limited 72-hour evaluation window ending September 13, 2026. You do not need a ChatGPT Plus (0/month) subscription or an OpenAI account to test prompts, but generations are subject to hourly traffic quotas, lack commercial copyright licenses, and disappear from your browser session upon page refresh.

- Casual hobbyists needing one-off conceptual image prompts without account signups
- Developers benchmarking prompt adherence against Imagen 3 and Midjourney side-by-side
Check before paying
- Outputs are stored temporarily in browser cache; you must manually save downloads immediately
- No private workspace; prompt inputs and image outputs may be utilized for academic LLM evaluation
- Zero commercial licensing; not legally cleared for client work or commercial merch prints
What Is the 72-Hour Free Window on Arena.ai?
Arena.ai (the independent text-to-image and model evaluation benchmark) frequently partners with frontier AI labs to stress-test cutting-edge models prior to broad commercial release. In this promotional benchmarking sprint, Arena.ai has unlocked a 72-hour free access window for OpenAI's GPT-Image generation model (specifically GPT-Image-2.5 Sunburst).
This temporary window allows creators, researchers, and hobbyists to test OpenAI's frontier visual generation capabilities directly inside Arena.ai without paying the standard 0/month ChatGPT Plus fee.
Direct Link and Step-by-Step Access on Arena.ai
1. Go directly to Arena.ai at arena.ai/image/direct?model_a=gpt-image-2.5-sunburst (or select Image Arena on arena.ai).
2. In the model dropdown, ensure the active model is set to the designated OpenAI GPT-Image preview model.
3. Enter your descriptive visual prompt into the text bar. The model generates photorealistic imagery, complex graphic typography, and multi-subject scenes directly in the browser stream.
4. Save your image immediately by right-clicking and downloading the file. Arena.ai does not maintain a persistent user gallery; your generated outputs vanish the moment you close or refresh the tab.
Crucial Limitations During the 72-Hour Event
Time-Limited Availability: This free access sprint is explicitly capped at 72 hours (ending September 13, 2026). Once the benchmark window closes, the model will either be rotated into blind side-by-side battles or restricted behind standard OpenAI API/ChatGPT subscriptions.
Dynamic Queue Capacity: Because global demand is extremely high during public evaluation windows, Arena.ai enforces real-time rate limiting. If the queue is saturated, you will see a temporary capacity warning. Waiting 5–10 minutes and retrying typically allows generation.
Zero Commercial Rights & Public Logging: All prompts and generated outputs on Arena.ai are public and can be used for model ranking leaderboards. Do not input proprietary company assets or confidential creative briefs.
