Best VPS for Deep Research (Self-Hosted)

Deep Research is an open-source AI agent that autonomously conducts comprehensive research on any topic. It iteratively refines its search queries, scrapes web content, and synthesizes findings using LLMs (GPT, Claude, O3-mini). Unlike traditional search, it dives deeper with each iteration — following threads, cross-referencing sources, and producing a structured research report. Self-host it with Docker for full privacy and unlimited usage.
