Wang says Meta is catching up to GPT-5.5, Opus with new «Watermelon»

Meta’s successor to «Avocado», or Muse Spark, is already in training and uses «an order of magnitude» more power, the head of the Superintelligence Lab, Alexandr Wang, said at an internal meeting.

The model is «coming soon» and will bring «big improvements in coding and agentic capabilities,» he adds in an X post.

The upcoming model has caught up with OpenAI’s GPT-5.5, he said, according to Business Insider, and added later on X that Opus is not far off.

Muse Spark was launched in April and performed sometimes on level with GPT-5.4, launched in March, quickly followed by GPT-5.5.

GPT-5.5 is, however, not the current state of the art any more, that would be Claude Fable or newly launched GPT-5.6, both of which face restrictions by the US government.

This isn’t discouraging the Superintelligence head, saying «I think you’ll like what we have cooking» on X.
