Meta AI Executive Insider Reveals: In-house training for the new model "Watermelon" has matched GPT-5.5

According to TrendForce's Beating Monitor, Alexandr Wang, Head of Meta's Superintelligence Labs, revealed during an internal staff meeting that the next-generation large model (codenamed "Watermelon") being trained has matched OpenAI's flagship GPT-5.5 in benchmark tests.

The new model is the successor to Meta's Muse Spark (internally known as "Avocado"), which was released in April, with a training computational power consumption increase of an order of magnitude compared to its predecessor.

Alexandr Wang also indicated on the X social platform that Muse Spark is about to receive an update focusing on enhancing programming and intelligence capabilities. When asked by users when it would match Anthropic's Claude Opus, he responded, "Soon."
