Meta's AI team announced muse spark 1.3, available in muse code and the Meta model API. The company calls it its most capable model yet, with frontier-level performance "almost too cheap to meter."

Key claims: major jumps in agentic and coding ability, improved usability. A third-party reply also claims it beats GPT 5.6 Sol on long-context evals, though that comparison is unverified commentary rather than official numbers.
