Core Capabilities
Seven Ways Muse Spark Changes How You Work
From instant answers to parallel multi-agent research, Muse Spark is the first AI model built to truly adapt to the complexity of every task.
Instant Mode — Real-Time, Zero-Latency Responses
Muse Spark's Instant mode is engineered for speed. It answers everyday queries, handles real-time voice interactions, and powers high-frequency assistants with minimal overhead. Whether you're integrating it into a live chatbot, asking quick questions via the Meta AI app, or using voice on your Ray-Ban glasses, Instant mode delivers high-quality output the moment you need it — no waiting, no thinking pause.
Thinking Mode — Step-by-Step Logic That Adapts
When a problem requires more than a quick answer, Thinking mode kicks in. Muse Spark works through tasks in a step-by-step fashion, switching strategies if its initial approach doesn't work — the hallmark of a true reasoning model. Ideal for math derivations, code debugging, contract analysis, and multi-layered strategic questions where accuracy matters more than speed.
Contemplating Mode — Parallel Multi-Agent Orchestration
Muse Spark's most powerful mode is designed to compete directly with Gemini Deep Think and GPT Pro. It breaks complex tasks into sub-tasks and launches multiple AI sub-agents to work simultaneously. Planning a family trip? One agent drafts the itinerary, another compares destinations, a third finds local events, and a fourth optimizes the budget — all in parallel. This is why Muse Spark scored 50.2% on Humanity's Last Exam, the highest of any model globally.
Native Multimodal — Visual Chain-of-Thought
Muse Spark accepts voice, text, and image inputs natively — not as an add-on. Its Visual Chain-of-Thought capability annotates and analyzes images in real time as it reasons, rather than just describing them. It scored 86.4 on CharXiv (global #1 for chart and figure understanding), outperforming GPT-5.4 (82.8) and Gemini 3.1 Pro (80.2). Use it to analyze financial charts, interpret medical images, identify spatial objects, or extract data from any photo.
Health Intelligence — Trained with 1,000+ Physicians
Muse Spark's health capabilities were developed in collaboration with over 1,000 practicing physicians, making it uniquely qualified for medical reasoning. It scored 42.8 on HealthBench Hard — the global #1, ahead of GPT-5.4 (40.1) and significantly ahead of Gemini 3.1 Pro (20.6). Snap a photo of a meal to get detailed nutrition data, ask about exercise physiology, or explore open-ended medical questions with depth that rivals specialist knowledge.
Visual Programming — Build Apps and Games From a Prompt
Describe what you want, and Muse Spark builds it. Visual programming lets you create custom interactive websites, dashboards, and mini-games straight from a natural language prompt — no code required. Launch a party planning dashboard, spin up a retro arcade game, create a whimsical flight simulator, or build a data visualization tool for your team. It's full-stack creative output from a single sentence.
Shopping Mode & Ray-Ban Integration — AI in the Real World
Muse Spark powers a dedicated Shopping mode that draws on creator content and community signals across Meta's platforms — helping you discover what to wear, how to style a room, or what to gift someone, with contextual suggestions from people you already follow. On Ray-Ban Meta AI glasses, Muse Spark goes hands-free: providing real-time answers, visual analysis of your surroundings, live translations, guided navigation, and task assistance through voice and gesture — all without touching a screen.
