{"answer":"Recommended action: Switch the Bedrock Region (settings or AWS_REGION) to one where the model is enabled; for Mantle models attach bedrock-mantle permissions and use a Mantle-supported Region; configure either access keys or an API key, not both.\n\nOption: Switch the Bedrock Region (settings or AWS_REGION) to one where the model is enabled; for Mantle models attach bedrock-mantle permissions and use a Mantle-supported Region; configure either access keys or an API key, not both. [evidence: official_recommended_action]\nApplies when: Selecting Bedrock models in Zed's agent, especially Mantle-routed ones\nSteps:\n1. Check model access in the Bedrock console for your Region.\n2. For Mantle models attach AmazonBedrockMantleInferenceAccess (or equivalent).\n3. Use a Region from the Mantle list (e.g. us-east-1, us-west-2, eu-west-1).\nExpected: The error no longer appears.","applicability":{"state":"unknown"},"limitations":{"state":"unknown"},"risk_notes":null,"success_criteria":null,"sources":[],"id":"f769fccd-a10f-4f76-906d-ddec3eecac05","kind":"solution","title":"Proposed fix: [Zed + Amazon Bedrock] '<model> is not available in <region>.
