Troubleshooting

Why doesn’t Tabnine CLI work with the agent?

Tabnine CLI requires Tabnine Agents to be enabled for your team.

If Agents aren’t enabled for your team, agent workflows and tools won’t work (even if sign-in works).

Ask your Tabnine admin to enable Agents for your team in the Admin Console, then restart Tabnine CLI.

Why is Tabnine CLI slow?

Common causes:
