      "zh": "Meta 9 月 2 日发布 Muse Spark 1.3，即日起进入 Muse Code 与 Meta Model API。主打长程智能体工作流：单个长线程里并行多项任务、遇到模糊指令主动追问、卡住时向用户求助、重大操作前先确认。按 Meta 工程师的内部对比，它编码更省——约少 20% 工具调用、约少 25% token，且对自身能力边界更自知，撞墙时承认而不是编造结果。max reasoning 模式待补充安全测试后上线；开放权重在路线图中，本次未发布。",
      "en": "Meta shipped Muse Spark 1.3 on Sep 2, now rolling out in Muse Code and the Meta Model API. It targets longer-horizon agentic work: juggling multiple workflows in one thread, asking clarifying questions, requesting help when stuck, confirming before consequential actions. In Meta engineers' internal comparisons it codes leaner (~20% fewer tool calls, ~25% fewer tokens) and is better calibrated about its limits instead of hallucinating outcomes. Max reasoning lands after more safety testing; open weights stay roadmap-only."
    },
    "why": {
      "zh": "Meta 主线模型第一次带上可对照的用量口径：约省 20% 工具调用、25% token 出自官方工程师对比，对已接入或正在评估 Meta Model API 的团队是即时的成本与适配信号；max reasoning 与开放权重两个未落地项，给出了明确的后续跟踪点。",
      "en": "Meta's mainline model now carries a comparable usage figure: ~20% fewer tool calls and ~25% fewer tokens from the vendor's own engineer comparisons — an immediate cost and adaptation signal for teams on or evaluating the Meta Model API. Max reasoning and open weights are two concrete follow-up points."

      "zh": "证据来源为 Meta 官方研究博客（厂商自述口径）与 AIHOT/AlphaSignal 同日聚合（BitShovel 于 2026-09-03 抓取核对原文）。约 20%/25% 的节省来自 Meta 工程师内部对比；「AA 智能指数 61-62」出自聚合端转述，非 Meta 官方页数字；两者都不是独立复测，上述内容不是独立评测，聚合端热度也不能证明质量或实际采用。",
      "en": "Evidence: Meta's official research blog (vendor self-report) plus same-day AIHOT/AlphaSignal aggregation (BitShovel fetched and checked the original on 2026-09-03). The ~20%/25% savings are Meta engineers' internal comparisons; the AA-index 61-62 figure is aggregator relay, not on Meta's page — neither is an independent re-test. This is not an independent review, and aggregator attention is not proof of quality or adoption."
