Available models

Claude Platform on AWS offers the same set of Claude models as the first-party Claude API.

For the current list of models, model IDs, context window sizes, and capabilities, see Models overview in the Anthropic documentation.

Model IDs

Model IDs on Claude Platform on AWS are identical to those used on the first-party Claude API (for example, claude-opus-4-6, claude-sonnet-4-6, claude-haiku-4-5). There are no Bedrock-style ARNs or anthropic. prefixes — use the model ID exactly as Anthropic publishes it.
