O'Reilly's November Radar notes Meta's Muse Spark Open, an open-weight model with 816 billion parameters and 42 billion active, claimed to compete with the best Chinese open models, plus Muse Wonder and Wonder Full claimed at frontier parity for financial and legal work. The same piece warns that Muse is a privacy and security risk in the author's view, a claim that remains opinion rather than an official finding.
