Meta's AI chief, Alexandr Wang, said in an internal town hall that Meta's upcoming AI model, codenamed Watermelon, has caught up with OpenAI's flagship GPT-5.5 model, based on closely followed AI model benchmarks. Wang stated that Watermelon, the next model after Avocado, is currently in training and uses an order of magnitude more compute than Avocado. In a post on X, Wang said an update to the current model Muse Spark is coming soon with major gains in coding and agentic capabilities. When asked when Meta would have a coding model on par with Anthropic's Claude Opus, Wang replied "pretty soon." GPT-5.5 is a model OpenAI released in April of this year; OpenAI debuted its most powerful model yet, GPT-5.6, late last month but has not released it generally. Meta declined to comment, and OpenAI did not respond to a request for comment.
