Fable 5.2 登顶 LiveBench 榜首
Fable 5.2 刚上了 LiveBench 第一名，跑长智能体任务比 Astra 稳，token 价格还更便宜。做智能体应用的开发者可以在 ChatLLM 的 Max 模式里直接试用，和 Astra 对比一下再决定用哪个。
Fable 5.2 发布，在 LiveBench 排行榜上拿下第一名，整体成绩超过 Astra。该模型在长程智能体任务循环中表现出色，适合需要多步工具调用和持续执行的场景。价格方面，Fable 5.2 的每百万 token 成本低于 Astra，性能与成本同时占优。模型现已上架 ChatLLM 平台，并可在 Max 模式下使用。
LiveBench 是一个持续更新的基准榜单，登顶意味着 Fable 5.2 在当前版本的评测集中综合能力领先。对于构建智能体应用的开发者来说，长 agentic loop 能力和更低的 token 成本是两个直接相关的选型指标：前者决定任务能否稳定跑完，后者决定规模化运行的成本。如果需要对比选型，可以把 Fable 5.2 与 Astra 放在同一工作负载下测试，验证榜单成绩在实际场景中是否成立。
🚨 Fable 5.2 Takes #1 Spot On LiveBench
- extremely good at long agentic loops - outperforms Astra overall - cheaper cost per 1M tokens
