It now also has a bearer mode, where a bearer token (a single access key sent with each request) is used to sign in.\n\nIn this build the value that would supply that token is always empty, so the new mode is never used.\n\n**Why**\n\nNothing changes for Vertex AI users yet. It is groundwork for signing in to Vertex AI with a bearer token.\n\n- Area: Cloud Providers\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 4\/5\n- Scope: org\n- Heads-up: no\n- Present in the build but not switched on"}
