Muse Spark 1.1
Nobody called this one. On Thursday, Jul 9 — with no teaser, no leak trail and no prediction market — Meta shipped Muse Spark 1.1 and opened the Meta Model API to developers: the first time Meta has charged for a model, at roughly a quarter of Anthropic and OpenAI’s API rates. A multimodal, agent-focused reasoning model with a 1M-token context window, it upgrades April’s original Muse Spark from Meta Superintelligence Labs — and it landed on the busiest drop day of the year, opposite GPT-5.6 and Grok 4.5. Meta has since shipped Muse Spark 1.2 (Aug 5) and 1.3 (Sep 2), and the watch has moved to Muse Spark 2.

Muse Spark 1.3 ships — and open weights go on Meta’s roadmap
Meta released Muse Spark 1.3 in Muse Code and the Meta Model API. In comparisons by Meta engineers it used ~20% fewer tool calls and ~25% fewer tokens than 1.2. Meta says its roadmap includes “bigger models, the Muse Spark open weights release, and more” — no date given. via Meta
Muse Spark 1.2 ships with Muse Code, Meta’s coding agent
Meta released Muse Spark 1.2, a coding-focused update, alongside Muse Code, a terminal coding agent for macOS and Linux powered by it. Both are available through the Meta Model API with expanded global access. via Meta · 9to5Mac
Muse Spark 1.1 drops with zero warning — Meta’s first paid model
With no pre-announcement, Meta shipped Muse Spark 1.1 and opened the Meta Model API in public preview — the first time Meta has charged for a model, the same paid-API business Anthropic and OpenAI run. A multimodal reasoning model built for agentic tasks — tool use, computer use, coding — with a 1M-token context window. It shipped into the busiest drop day of the year, opposite GPT-5.6 and Grok 4.5. via Bloomberg · CNBC · Meta
The price is the strategy: ~¼ of Anthropic and OpenAI’s rates
The paid Meta Model API undercuts the incumbents at roughly one-quarter of Anthropic and OpenAI’s API pricing — a land-grab price for an agentic model with a 1M-token window. Still open: independent benchmarks (early first-party claims only) and where the closed Spark line leaves Llama 5’s expected open-weights release. Muse Spark 2 is already armed on the watchlist. via TechTimes · Quartz
The original Muse Spark debuted in April — free
Muse Spark 1.1 is the second model from Meta Superintelligence Labs, upgrading April’s original Muse Spark. The line itself wasn’t the surprise — charging for it was: a business-model turn no leak cycle called, landing while the watchlist carried Llama 5 (“open weights expected”) as Meta’s presumed next move. via Meta · DataCamp
