75| `gen_ai.provider.name` | `string` | The platform that serves the request: `aws.bedrock` on Amazon Bedrock (Mantle included), `gcp.vertex_ai` on Google Cloud’s Agent Platform, and `anthropic` everywhere else. On every span. |

It appears on the request’s API span and on every API span under it, such as the session turns that the request starts.<br />Use an opaque ID, such as your database’s key for the user.<br />**Do not put an email address in this value.** To protect user privacy, the API drops any `user.id` that contains one. |
