Muse Spark 1.3Muse Spark 1.3（Meta）
Meta Superintelligence Labs 2026-09-02 发布的闭源多模态推理模型，主攻长周期智能体与编码：1M 上下文、131K 输出，输入 $1.25 / 输出 $4.25 每百万 tokens（缓存读 $0.15）。Meta 自测 DeepSWE v1.1 75.4、Terminal-Bench 2.1 88.8、MRCR 512K-1M 长文档召回 98.1；官方开放 xhigh 推理档，max 档待安全测试后放行。另设「贡献者」低价端点 $0.10/$0.20，代价是 Meta 可用你的流量训练模型。适合整仓检索、长文档一次性读完的场景。Meta Superintelligence Labs' closed multimodal reasoning model, released 2026-09-02 for long-horizon agents and coding: 1M context, 131K output, at $1.25 input / $4.25 output per million tokens (cache reads $0.15). Meta reports 75.4 on DeepSWE v1.1, 88.8 on Terminal-Bench 2.1 and 98.1 long-document recall on MRCR 512K-1M. The xhigh reasoning tier ships today; max remains gated pending safety testing. A 'contributor' endpoint at $0.10/$0.20 trades data rights for a steep discount. Best suited to whole-repo retrieval and single-pass long-document reading.
