Mysterious 'mona-lisa-1' model appears in blind test, likely new GPT-Image

A mysterious image model called 'mona-lisa-1' showed up in the blind test list on LM Arena. A tipster said that when they submitted images made by this model to OpenAI's official verification tool, it detected signals linked to OpenAI, so people think it might be a new GPT-Image model. OpenAI hasn't made any official announcement yet, and hasn't confirmed how it relates to their existing products.

Testers compared it with GPT-Image 2 using the same prompts and found that 'mona-lisa-1' gives richer details. Many testers said the model is only in blind testing for now, not available in ChatGPT, OpenAI API, or Codex. Some comparisons show it does better in realism and reducing the typical AI look, but some results still have noise or artifacts.

It's worth noting that GPT-Image 2 also appeared anonymously on Arena before its release. Right now, we don't know the technical details or release date of 'mona-lisa-1'. OpenAI's Verify page says that detecting a source signal only means the content might have been made with OpenAI tools, but it can't confirm which specific model. So we can't be sure 'mona-lisa-1' is the direct successor to GPT-Image 2.
