Meta CEO Mark Zuckerberg, who has been inactive on X (formerly Twitter) for almost 3 years, returns to the platform to announce the launch of Muse Spark 1.1. This launch hints at an aggressive push into the paid AI market, which is designed to compete with OpenAI and Anthropic.

Meta launched Muse Spark, its first AI model from restructured Meta Superintelligence Labs, promising tenfold compute gains over Llama 4 Maverick.

Meta is upgrading its Muse Spark artificial intelligence model under the leadership of AI chief Alexandr Wang.
