-Fill in the provider's form: a **Model Name** to recognize it later, **Input** and **Output Token Cost Per Million Tokens** for cost tracking, and the provider's credentials, an API key for Open AI, region and access keys for Bedrock or Sagemaker, a service account for Vertex AI, endpoint and key for Azure. A token cost can be 0, for a model you host yourself for example, but not negative. A **Form** and **JSON** toggle lets you fill the fields individually or paste a raw config.

+For AWS Bedrock, **Model Name is the invocation ID**, not a label you invent. Copy a chat foundation-model ID such as `anthropic.claude-3-haiku-20240307-v1:0`, or a system inference-profile ID such as `us.anthropic.claude-3-5-sonnet-20241022-v2:0`, from the AWS console. A family name such as `Claude` is rejected. Connecting a model does not train or import one in AWS. Save sends a small validation request to AWS and can incur provider charges. New application-profile ARNs, provisioned throughput, and session-token or role credentials are not supported by this form.
