Get list of models
Amazon Bedrock provides two separate inference endpoints, each with its own API for listing the models available on it. For an overview of the endpoints, see Endpoints supported by Amazon Bedrock.
-
bedrock-mantle – Use the OpenAI-compatible /models endpoint (for example, client.models.list() with the OpenAI SDK) to list the models available on bedrock-mantle.
-
bedrock-runtime – Use the AWS-native ListFoundationModels API. The response returns a FoundationModelSummary object for each model, including its ARN, model ID, supported modalities and features, and deprecation status. To get details for a specific model, use GetFoundationModel, specifying the model ID.
The response also returns model IDs that aren't in the base model ID or base model IDs for Provisioned Throughput charts. These model IDs are deprecated or for backwards compatibility.

List models on bedrock-mantle
- OpenAI SDK (Python)
-
# List all available models using the OpenAI SDK
# Requires OPENAI_API_KEY and OPENAI_BASE_URL environment variables
from openai import OpenAI
client = OpenAI()
models = client.models.list()
for model in models.data:
print(model.id)
- Anthropic SDK (Python)
-
from anthropic import AnthropicBedrockMantle
client = AnthropicBedrockMantle(aws_region="us-east-1")
models = client.models.list()
for model in models.data:
print(model.id)
The bedrock-mantle /v1/models endpoint returns OpenAI-shaped model entries. Only model.id is reliable when using the Anthropic SDK; other fields on ModelInfo may be empty.
