Reka frames it as a direct replacement for agentic pipelines that pass work between modality-specific models. What Rho-1 Changes Most multimodal systems today are pipelines. A central model plans, then hands jobs to specialists for images, video or detection. Each handoff adds latency, and each specialist sees only a narrow request. Rho-1 removes those handoffs
