Mona Lisa 1 is an unannounced image model name reported in Arena blind battles. A follow-up codename, luna-lisa-alpha, appeared on August 20, 2026. OpenAI shipped ChatGPT Images 2.5 on September 8, but has not connected either codename to that release — the match remains community speculation.

Water cycle illustration
Lucas van de Runstraat · Arena observation
Create a friendly educational illustration showing the complete journey of water through the natural water cycle in one coherent landscape: ocean evaporation, cloud formation, rainfall over mountains, streams, groundwater and rivers returning to the sea. Visually easy for children aged 8–10 to understand, scientifically sensible, no text.
Geometrically consistent mirror
Lucas van de Runstraat · Arena observation
A person stands in front of a large mirror cracked into 18 irregular pieces, with none missing. Each fragment remains in the original mirror plane but reflects a different portion of the same person and room according to its exact position. The combined fragments must reconstruct one geometrically consistent reflection rather than 18 independent portraits.
Seven-line metro map
Lucas van de Runstraat · Arena observation
Design a fictional metro map containing exactly 7 lines and 42 uniquely named stations. Every line must have two endpoints. Exactly 9 stations are interchanges, including one station where four lines meet. Below the map include a complete alphabetical station index whose names correspond exactly to the stations shown on the map. Clean professional transit-design typography, no duplicate station names.

Two codenames appeared in Arena, OpenAI has since shipped a major image release, and the link between them is still an inference.
Testers reported mona-lisa-1 from August 9, 2026, and luna-lisa-alpha as a follow-up checkpoint from August 20. EvoLink also documented one Arena battle under the exact mona-lisa-1 label on August 11. Both names stayed inside anonymous battles and never reached the public leaderboard.
On September 8, 2026, OpenAI released ChatGPT Images 2.5 with the gpt-image-2.5-flare and gpt-image-2.5-sunburst API models. The announcement never mentions Arena testing or either codename, so it confirms the release, not the codename match.
OpenAI has not said that mona-lisa-1 or luna-lisa-alpha is a test checkpoint of Images 2.5. Attribution to OpenAI itself still rests on provenance reports that could not be independently reproduced, so both links remain community speculation.

The early sample set highlights four areas worth watching. These are observations to test against more evidence, not verified model capabilities.
Early comparisons draw attention to ordinary skin, sensor noise, imperfect framing, and unpolished light instead of a uniformly synthetic campaign look.
Dense scenes provide a useful test of signs, vehicles, storefront details, reflections, and requested text appearing in the right place.
Constraint-heavy prompts show which requested details survive the full image and where plausible but incorrect substitutions still appear.
Repeated tests can reveal whether the requested photographic language holds across outputs or shifts enough to change the creative decision.

Mona Lisa 1 is an unannounced image model name reported by community testers in Arena. Its developer, final identity, capabilities, and release status have not been officially confirmed.
It may be, and several community posts explicitly make that attribution. However, this remains community speculation. OpenAI has not announced Mona Lisa 1, and the September 8 ChatGPT Images 2.5 release notes never mention either Arena codename.
A tester reported that an Arena output was detected by OpenAI Verify as likely originating from OpenAI tools. The original file and result have not been independently reproduced, and even a valid provenance signal would not identify the model, its product name, or its release plan.
Yes. EvoLink documented one Arena Battle Mode session on August 11, 2026 where the revealed candidate label was mona-lisa-1. This confirms one callable Arena session, not public access, stable availability, or a controlled quality result.
That is the leading community hypothesis, still unconfirmed. OpenAI shipped ChatGPT Images 2.5 on September 8, 2026 with the gpt-image-2.5-flare and gpt-image-2.5-sunburst API models, but has never connected Mona Lisa 1 to them, and no official material uses either Arena codename.
A second anonymous codename reported in Arena battles from August 20, 2026, after mona-lisa-1. Testers describe it as a newer checkpoint of the same line, with stronger realism and text rendering but still some artifacts on small details. It carries the same evidence level: an Arena observation with no official confirmation.
No. There is no public Mona Lisa 1 endpoint on this site. The separate Create workspace uses the publicly available GPT Image 2 service and labels that model directly.
The name itself has nothing to wait for: OpenAI shipped ChatGPT Images 2.5 on September 8, 2026 without mentioning it. What stays open is whether the codename link is ever confirmed, and the waitlist only sends that kind of source-backed change.
No. Arena images on this site are community-sourced observations. Each published item must retain its author, original post, prompt when available, and evidence level.
No. mona-lisa-1.app is an independent model watch and image-creation product. It is not affiliated with OpenAI, Arena, or another model provider.
The working image generator uses GPT Image 2. Mona Lisa 1 is not offered as a model option.
