Meta's 'Watermelon' AI model reportedly matches OpenAI's GPT-5.5

Meta is reportedly training a new AI model named 'Watermelon' that its superintelligence chief Alexandr Wang claims is on par with OpenAI's GPT-5.5. This development comes as Meta continues its significant investment in AI, with Wang suggesting an "Opus-level" coding model could be released soon. While Watermelon is still in training and requires substantial compute, its performance could mark a notable improvement for Meta's AI capabilities, though the rapidly advancing frontier of AI models presents ongoing competition.
