最新开源模型（第18期）：Arcee 400B MoE、LiquidAI 被低估的 1B 模型、新版 Kimi，以及本月密集发布的预期
阅读原文· interconnects.ai本期开源模型动态涵盖 Arcee 400B MoE、LiquidAI 1B 及新版 Kimi 等实用小众模型。Arcee 发布 4000 亿参数 MoE 架构模型，LiquidAI 推出性能被低估的 10 亿参数方案，Kimi 迎来重要更新。业界预期本月将迎来密集的大模型发布潮，多款重要产品即将面世。
January was on the slower side of open model releases compared to the record-setting year that was 2025. While there were still plenty of very strong and noteworthy models, most of the AI industry is looking ahead to models coming soon. There have been countless rumors of DeepSeek V4’s looming release and impressive capabilities alongside a far more competitive open model ecosystem.
In the general AI world, rumors for Claude Sonnet 5’s release potentially being tomorrow have been under debate all weekend. We’re excited for what comes next — for now, plenty of new open models to tinker with.
Our Picks
LFM2.5-1.2B-Instruct by LiquidAI: Liquid continued pretraining from 10T (of their 2.0 series) to 28T tokens and it shows! This model update really surprised us: In our vibe testing, it came very close to Qwen3 4B 2507 Instruct, which we use every day. And this model is over 3 times smaller! In a direct comparison against the (still bigger) Qwen3 1.6B, we preferred LFM2.5 basically every time. And this time, they released all the other variants at once, i.e., a Japanese version, a vision and an audio model.
