Meta Muse Spark 1.1

Announced July 9, 2026 as the second model from Meta Superintelligence Labs and the launch model for the Meta Model API, marking the end of Meta's open-weights-only era and its first paid API. A multimodal reasoning model built for agentic work: it accepts text, images, video, audio and PDFs, returns text, and is designed to orchestrate multi-agent workflows as either a planning main agent or a subagent. The API is OpenAI-compatible with structured output and parallel tool calling, and new accounts get $20 in free credits. Mark Zuckerberg pitched the pricing as roughly a quarter of what Anthropic and OpenAI charge for comparable models.

Meta Muse Spark 1.1 strengths

• Aggressive pricing for an agentic frontier-tier model
• Broad input support: text, image, video, audio, PDF
• 1M-token context window
• Built for multi-agent orchestration (main agent or subagent)
• OpenAI-compatible API with parallel tool calling

Pricing & context

Cost guide: a typical call of about 10K input + 2K output tokens costs roughly $0.021 at list prices. Worth modelling against cheaper tiers before committing high-volume traffic.

When to choose Meta Muse Spark 1.1

Meta Muse Spark 1.1 is best for cost-sensitive coding and computer-use agents that need long context and a drop-in OpenAI-compatible API. If your workload is more cost-sensitive, weigh it against gpt-oss-120b (≈$0.03 input /1M) first.
