Muse Spark 1.2 Contributor Version Available for Free for a Limited Time

Meta's Muse Spark 1.2 Contributor version is rapidly being rolled out to third-party platforms. After integration with OpenRouter, the pricing aligns with Meta's official rates: $0.1 per million tokens for input, $0.2 for output, and only $0.002 for cached input. The standard version is priced at $1.25, $4.25, and $0.15. The Contributor version utilizes the same model and capabilities, with user input and output available for Meta's training, making it approximately 95% cheaper than the standard version based on output pricing. Currently, OpenCode Zen has made the Contributor version a limited-time free model, and Command Code has also integrated, with the lowest tier Go package available. Vercel AI Gateway and NanoGPT provide APIs, and Vercel can also integrate tools like Claude Code, Codex, Hermes, OpenCode, and OpenClaw. Artificial Analysis gives Muse Spark 1.2 xhigh an Intelligence Index of 57, with prices being remarkably low, but community feedback is mixed. Some view it as a low-cost alternative to DeepSeek V4 Flash, while others report that long tasks and tool calls are not reliable enough, making it suitable for public code and low-cost experiments, while private code requires consideration of whether data is willing to be shared with Meta.
