Auto-generated by model-addition-agent for aws-bedrock-mantle/anthropic.claude-opus-4-6.


Note

Low Risk
Metadata-only addition with no application logic; incomplete regional pricing may affect cost estimates until rates are added.

Overview
Adds a new aws-bedrock-mantle provider definition for anthropic.claude-opus-4-6, marking it active and serverless chat with thinking enabled.

The entry documents a 1M context window, 128k max output, text/image input, and standard Claude capabilities (prompt caching, tools, structured output). Cost blocks for us-west-2 and us-east-2 are placeholders only—no per-token rates until bedrock-mantle pricing is published—with links to AWS and Anthropic docs as sources.

Missing Anthropic mantle path prefix

High Severity

The file omits extra_configuration.bedrock_mantle_adhoc_prefix. Every other Anthropic model in this provider sets it to /anthropic, matching AWS's /anthropic/v1/messages path. Without it the gateway calls the plain /v1 path and requests fail.

Structured output unsupported on mantle

High Severity

structured_output is listed as a feature, but AWS rejects structured outputs on the bedrock-mantle Anthropic Messages path with a 400. Sibling Anthropic mantle models omit this flag for that reason. Callers who enable structured output from this catalog entry will get failed requests.

Incomplete Anthropic feature flags

Medium Severity

The features list is missing parallel_function_calling and assistant_prefill. Every other Anthropic model in this provider declares both, and Claude Opus 4.6 supports them on Anthropic and Bedrock. The catalog will hide those capabilities from callers.
