Meta's Watermelon AI Catches GPT-5.5, Wang Says

At an internal town hall, Meta AI chief Alexandr Wang said Watermelon—the successor to Muse Spark’s Avocado—is in training and has caught up with OpenAI's GPT-5.5 on benchmarks, with Watermelon using an order-of-magnitude more compute than Avocado. Meta also signaled a Muse Spark update to boost coding and agentic capabilities to close the gap with rivals like OpenAI and Anthropic, as the company continues heavy investment in chips, data centers, and talent despite ongoing adoption challenges.
