   MetaCircle raises hundreds of millions of yuan in seed and seed+ rounds

   InfoQ China reports that AI startup MetaCircle has closed seed and seed+ funding rounds totaling hundreds of millions of yuan, with the seed round led by Shunwei Capital and the seed+ round including Shanghai Semiconductor Industry Investment, 360 Strategic Investment and BV Baidu Ventures. The company says the money will go to core algorithm research, exploratory product work, hiring and evaluation benchmarks. Founded in May 2026, MetaCircle is led by Liu Ziming, an assistant professor at Tsinghua's Institute for AI who was a co-author of KAN; its "Meta Model" aims to learn relationships between architectures, training configurations and experimental outcomes to predict training performance and help design architectures. The report notes that predicting performance and autonomously designing better architectures are different capability levels, and that full evaluation conditions and reproducible results for its time-series and world-model experiments were not provided.

   OpenRSI Index benchmarks whether AI agents can improve real ML research

   OpenRSI Index, launched by the OpenRSI Foundation, has drawn attention on X, where its announcement post has passed 133,000 views. The benchmark draws tasks from real open-source research projects such as Marin, Qwen and GPIC, handing agents existing models, code, data and training recipes to improve, spanning pretraining, post-training and image generation, with the site listing representative single runs at roughly 5,815 to 20,864 H100-hours. Evaluation uses an RSI-Harness that separates the agent's workspace from a clean judging environment, pausing and snapshotting the workspace for scoring; advisers include Luke Zettlemoyer, Karthik Narasimhan, Yejin Choi and Dawn Song, and a companion RSI-Anything pipeline lets researchers turn their own open problems into runnable RSI tasks.
