Meta Releases Muse Spark 1.3: Claims It Can Finally Compete with OpenAI and Anthropic

Meta has released Muse Spark 1.3, its most powerful AI model yet. Meta's Chief AI Officer calls it the company's biggest jump in model performance. The model uses 25% fewer tokens, handles multiple workflows simultaneously, and recognizes its own limitations, pausing to ask for clarification before irreversible actions. Whether Meta will open-source the model weights remains undecided, though older Muse Spark 1.2 weights are still planned for release.
