“Meta says Muse Spark 1.3 has frontier performance — but its best results come from a model developers can’t broadly use yet”

Key points

• Muse Spark 1.3 offers faster, stronger benchmarks than 1.2 across long-running tasks.
• The max configuration ranks in the frontier cluster, though not the absolute leader.
• The shipping model uses existing reasoning settings; max variant awaits further safety testing.
• Price remains unchanged at $1.25 input, $4.25 output per million tokens.
• Enterprise users may value reduced tool calls and tokens, despite pricing stability.
