Liquid AI 发布 LFM3 开放权重模型家族，共 6 个模型实例，覆盖文本、音频、视觉和 omni 模态，其中 LFM3-1.7B 文本模型支持 256k 上下文窗口。作者指出性能提升来自 tri-hybrid 设计，24 层中 13 层为短卷积、5 层使用 256 token 滑动窗口注意力、6 层做全局注意力。在 Liquid 自己运行的智能体基准中，1.7B 模型在 AutomationBench 上得分 41.29，Qwen3.5-9B 为 15.10。

Liquid AI just launched LFM3, an open-weight model family whose 1.7B text model beats its 2.6B predecessor.
The gain comes from a tri-hybrid design: of 24 layers, 13 are short convolutions, 5 use 256-token sliding-window attention and 6 attend globally.
That efficiency carries into agent benchmarks run by Liquid, where the 1.7B model scores 41.29 on AutomationBench while Qwen3.5-9B manages 15.10.
Introducing 𝙻𝙵𝙼𝟹: our new generation of Liquid Foundation Models.
