OpenSeek aims to unite global open-source communities to collaboratively advance algorithms, data, and systems for next-generation models. In stage one, we released CCI4.0, OpenSeek-small, and OpenSeek-Pipeline, developed the DualPipe-V strategy in FlagScale, and launched a collaborative task with the PAZHOU Competition to support community contributions. The initiative is organized into three dedicated working groups, focusing respectively on data, algorithms, and systems.
