Grok Bot's persistent-agent pitch is something you can build yourself with a VPS and model routing

A Reddit user dissects xAI's Grok Bot pitch: persistent agents that outlive a session, run on their own compute, and start work unprompted. The direction is right, he argues, but the price is lock-in to one platform's compute, account system, and—more importantly—one model for every task.
Persistence isn't proprietary magic: it's just an agent on an always-on server. He runs his own on a cheap VPS with schedules and event reactions, fully under his control.
The bigger lock-in is the model, since tokens are the largest ongoing agent cost. Self-hosting lets you route per task: cheap models like Haiku, DeepSeek, or Qwen handle high-volume boring work (reading, sorting, extracting, summarizing), while expensive Opus/GPT-5-tier calls are reserved for the few moments needing hard reasoning. That split is the whole game—and exactly what a single-vendor platform can't offer.
