Muse Spark 1.2 (also referred to as Musepark 1.2) is a proprietary language model from Meta, described by creators as focused on coding and agentic workflows. It reportedly supports a context window of about 1 million tokens and accepts multimodal input.
According to creator coverage, Meta's self-reported benchmarks look strong, but independent leaderboards place it lower. One reviewer cited 59.3% on Deep SWE, below top OpenAI and Anthropic models. In a creator's SVG benchmark test it took about 35 seconds and cost roughly 4.5 cents, and it was described as a cheap, solid alternative rather than a top-tier model.
It is reportedly available only through an API, with no open weights. No official page was available for verification, so pricing, exact release date, and regional availability details are unconfirmed.
