Meta Muse Spark 1.2 and Muse Code: Persistent Async Agents, Co-Trained Harness, and the $0.10/M Data-Share Pricing Play
On August 5, 2026, Meta released Muse Spark 1.2 and Muse Code — a coding-specialized model co-trained with its own terminal agent harness, featuring persistent async background agents, replay-exact event logging, and a controversial contributor pricing tier at $0.10/M input tokens in exchange for training data rights. Covers the co-training methodology, benchmark results (82.9% Terminal-Bench 2.1, 59.3% DeepSWE 1.1), the GPU kernel optimization case study, the two-tier pricing strategy, and strategic implications for the agentic coding landscape.
