[Muse Spark 1.1 Launches on OpenRouter, Still Limited to U.S. Users] According to monitoring by 动察 Beating, Meta's Muse Spark 1.1 has launched on OpenRouter and is currently only available to U.S. developers. Developers can access it via OpenAI-compatible interfaces without needing to integrate the Meta Model API separately. The model supports a 1 million token context and can handle text, images, audio, video, and PDFs. It is primarily designed for programming, tool invocation, and Agent tasks. The pricing for the model on OpenRouter is identical to Meta's official API: $1.25 per million input tokens, $0.15 for cached input, and $4.25 for output. Network searches are priced at $2.50 per 1,000 queries. However, OpenRouter charges an additional 5.5% service fee when purchasing credits, with a minimum fee of $0.80. [Original Link]
