Modal has introduced "Sidecars," a new feature designed to enhance the security and performance of sandboxed environments for executing untrusted code, particularly for AI agents. Sidecars are isolated containers that run alongside the main sandbox on the same host, creating a stronger security boundary and enabling up to three times faster communication between trusted and untrusted code. This addresses the challenge of agents needing capabilities without direct access to sensitive credentials, a problem exacerbated by older agent designs that combined harness logic with tool calls.
