Open-Gen Attempts to Replicate GEN 1.5 Embodied Model Architecture

KyeGomez launched Open-Gen, an open-source effort to reconstruct Generalist AI's embodied foundation model GEN 1.5. The project hypothesizes the architecture, including using Flow Matching for action chunking and masking rules for asynchronous sensor/action streams. The author clarifies this is an independent reconstruction based on public evidence and invites community validation.
