Summary
Meta told employees its in-training Watermelon model has caught up with OpenAI's GPT-5.5, according to people familiar with an internal town hall led by superintelligence chief Alexandr Wang.
Watermelon follows April's Muse Spark release and uses an order of magnitude more compute than Avocado, Wang said, though the specific benchmarks behind the claim were not disclosed.
Wang also signaled a near-term Muse Spark update with major gains in coding and agentic capabilities, saying Meta could reach Anthropic Claude Opus-level coding performance "pretty soon."
The claim would mark Meta's clearest sign of progress after earlier models lagged OpenAI and Anthropic, as Zuckerberg ramps up hiring and plans $125 billion to $145 billion in infrastructure spending this year.
