Meta has released its most powerful AI model to date, Muse Spark 1.3. Developers can access this model on a paid basis starting Wednesday, and Meta will soon roll out this update to its social media platforms and Meta AI users. Meta's Chief AI Officer stated that this represents the company's biggest leap in model performance. The new model has made significant advancements in programming and agent capabilities, with performance comparable to that of the AI models recently released by OpenAI and Anthropic. In programming tasks, Muse Spark 1.3 outperforms OpenAI's GPT-5.6 Sol and is competitive with Anthropic's Claude Fable 5.1. However, OpenAI is about to release an even more advanced new model, Astra.
