AI Gateways Let Teams Change Models Without Rebuilding Their Stack
As AI budgets face closer scrutiny, Remy Guercio of Tailscale argues that standardizing on one vendor is not a lasting answer to rising costs or AI lock-in. In his account, teams need room to change models, connectors, interfaces and execution environments without replacing the whole stack. An AI gateway, he says, can preserve that choice while giving organizations a central way to manage access, set model-specific budgets and inspect what agents do.
Network Identity Moves Agent Credentials Out of the Sandbox
Remy Guercio of Tailscale argues that many agent sandboxes protect the runtime while leaving the more dangerous object inside it: the credential. In his account, Aperture, Tailscale’s LLM gateway, separates execution isolation from access control by keeping provider keys at the network layer and giving the agent only a placeholder. Routed through Tailscale’s WireGuard-based identity network, each LLM call carries a verified user, group, or machine identity, giving Aperture a central point for policy, logging, cost controls, hooks, and visibility into tool use.
