Meta has launched Muse Spark, a new hosted AI model competitive with top models like GPT-5.4 and Gemini 3.1 Pro, accessible via meta.ai with 'Instant' and 'Thinking' modes. The chat interface includes embedded tools for rendering SVG/HTML content, hinting at advanced multimodal capabilities. This marks Meta's first major model release since Llama 4 and reflects ongoing investments in agentic systems and coding workflows.
