Meta launched Muse Spark on April 8, 2026 — its most powerful AI model to date and the first to emerge from its newly formed Meta Superintelligence Labs. The model is live right now on the Meta AI app and meta.ai website, with a rollout to WhatsApp, Instagram, Facebook, and Messenger confirmed for the coming weeks.
For India, where over 500 million people use WhatsApp daily, this is not just another product launch — it lands directly in the hands of half a billion users.
This is Mark Zuckerberg’s most expensive bet yet. Over the past nine months, Meta rebuilt its entire AI stack from the ground up, led by Alexandr Wang — the 28-year-old founder of Scale AI, whom Meta hired as its first-ever Chief AI Officer after investing $14.3 billion for a 49% stake in Scale AI.
Muse Spark, internally codenamed “Avocado”, is the first model in Meta’s new “Muse” series. It runs in two modes — Instant for quick queries and Thinking for complex reasoning tasks — with a third “Contemplating” mode coming soon, where multiple AI sub-agents reason in parallel.
Meta’s stock jumped nearly 9% on the day of the announcement. The company has committed between $115 billion and $135 billion in AI-related capital spending in 2026 alone — nearly double what it spent in 2025.
What This Means for India
India is Meta’s largest market by users. WhatsApp alone has more than 500 million active users in the country, and Facebook and Instagram together add hundreds of millions more. When Muse Spark rolls out across these platforms in the coming weeks, it will become the AI model with the widest consumer reach in India — overnight.
For a country of 1.4 billion people where a majority of internet users access the web through Meta’s apps, this changes what everyday AI looks like. Indian developers and startups building on Meta’s ecosystem should watch the private API preview closely — paid API access to Muse Spark is expected to open to a wider audience after the initial partner preview ends.
At a time when India is racing to lead in AI, having a frontier model embedded inside the apps Indians use most is both an opportunity and a question about data privacy.

FAQs
Q1: What is Meta Muse Spark and how is it different from Llama?
Muse Spark is Meta’s newest and most capable AI model, built by its Meta Superintelligence Labs team under Alexandr Wang. Unlike the Llama series — which was open-source and freely downloadable — Muse Spark is proprietary and currently only available within Meta’s own apps and a restricted API preview. Meta has said it hopes to open-source future versions, but there is no confirmed timeline yet.
Q2: Will Muse Spark be available on WhatsApp in India?
Yes — Meta has officially confirmed that Muse Spark will roll out to WhatsApp, Instagram, Facebook, and Messenger in the coming weeks. India is one of WhatsApp’s largest markets with over 500 million users, making it one of the most significant deployments of any frontier AI model globally.
Q3: How does Muse Spark compare to ChatGPT and Google Gemini?
On most major benchmarks, Muse Spark is competitive but not the outright leader. It scored 89.5% on GPQA Diamond, trailing Gemini 3.1 Pro’s 94.3% and Claude Opus 4.6’s 92.7%. However, on HealthBench Hard — a test of health-related reasoning — Muse Spark scored 42.8%, beating all rivals. Meta itself acknowledged performance gaps in long-horizon agentic tasks and coding, and said it continues to invest in these areas.
