The official Grok Bot account announced on November 10 that xAI's AI assistant can now join personal and company tailnets through Tailscale. In practice, the Bot can now reach private MCP servers, internal tools and apps on the corporate network without those resources having to be exposed on the public internet.
What changes with Tailscale
Support for personal tailnets was already listed in the November 4 changelog for Grok Bot version 0.78.5. The new emphasis this week is on company networks: the Bot joins the tailnet as one more authorized device, and the network's access policies determine what it can reach.
A tailnet is the private network created by Tailscale: only approved devices and users join it, and access rules define who can talk to whom. Grok Bot, meanwhile, is xAI's agent product, in beta since August 2026 and described by the company as an “AI teammate” with its own computer, signing in to the tools you already use and working across apps and inboxes. With this integration, that teammate can now also reach what only exists inside the private network.
One caveat: neither the November 10 post nor the changelog says which subscription plans include the integration. And Tailscale's own documentation notes that a new tailnet's default policy lets devices talk to one another — administrators must narrow access themselves. For a company connecting an AI assistant to its internal network, defining exactly which tools it can reach matters as much as making the connection.
Grok 4.8 in the home stretch
The announcement lands the same week Elon Musk says Grok 4.8 is in the home stretch: according to him, pre-training is done and the model is in reinforcement learning, with a soft rollout to Bot users later this week. Musk also says xAI dropped JAX and SGLang and rewrote its reinforcement-learning and inference stacks from scratch in C and C++. These are Musk's statements, with no independent confirmation or firm date yet.
Background
Geekiki previously reported that Musk called Grok Bot's cost unsustainable after usage limits ran out before the end of the week (read here) and his promise that Grok 4.8 would be “incredibly useful” and would not prioritize benchmarks (read here).
