Meta ships Muse Spark 1.3, predicts rival model access cutoff and industry-wide token price war

Zuck announced Muse Spark 1.3, calling it Meta's biggest jump yet on coding and agentic work, with near-free frontier pricing, plus open-weights releases (Watermelon, Muse Spark) coming.

The quoted analysis argues Watermelon will hit 'Fable' class, proving Meta's experiment of having employees generate tens of thousands of RL environments works — no shortcut: compute + data + RL envs + good people. It predicts Meta will soon cut employees' access to Anthropic/OpenAI models, drive down per-token prices industry-wide, and that this could affect Anthropic's and OpenAI's IPOs.
