According to CoinMeta and OneMillion.AI, Arena has recreated a mysterious image generation model, luna-lisa-alpha. The community regards this as the new gpt following mona-lisa-1, which is still in the training phase. Testers have noted three main improvements: a more realistic appearance, better consistency in character features, and less granular noise. When generating the same character repeatedly, the appearance and style become more stable, with the noticeable granular texture seen in earlier versions like mona-lisa now largely eliminated. However, there may still be slight discrepancies in the details of more complex characters. Previously, mona-lisa-1 was identified as originating from OpenAI using image verification tools, so it is widely speculated that luna-lisa-alpha is also part of the same series of test models.
