Muse announced Spark 1.3, described by the company as its biggest jump yet on coding and agentic work, priced "almost too cheap to meter," available now in Muse Code and via API. Upcoming: a model codenamed 🍉 and open-weights releases. Aaron Levie notes that if open weights ship, it would reshape US open-weights competitiveness amid a breakneck week of AI releases.
