Cause (Documented platform behavior): Only openai, anthropic and cohere define a dedicated 403 class. google-genai uses ClientError with code 403 and status PERMISSION_DENIED; botocore produces a ClientError whose error code is AccessDeniedException (modeled with httpStatusCode 403 in the bedrock-runtime service model); azure-ai-inference's error_map omits 403 so HttpResponseError is raised; mistralai raises SDKError. None of the SDKs retry 403.
Fix status: documented_behavior
Misleading approaches:
- Assuming a 409 surfaced to your code happened once — openai/anthropic/cohere already retried it up to max_retries (default 2).
- Adding an outer tenacity loop on top of openai/anthropic default retries — effective attempts become (outer x 3).
Limitations:
- Compared from wheel source at the pinned versions only; messages and mappings change between SDK majors.
- Python SDKs only; the TypeScript/Java/Go SDKs of the same vendors have different class names.
Other error fragments:
- An error occurred ({error_code}) when calling the {operation_name} operation{retry_info}: {error_message}
- Operation returned an invalid status '{}'
- API error occurred
- headers: {self.headers}, status_code: {self.status_code}, body: {self.body}
- The requested resource could not be found.

Problem details
- Observed symptom
- Entitlement failures (model not enabled, region/workspace restriction, IAM missing bedrock:InvokeModel) surface under a different class per SDK; azure-ai-inference has no 403 subclass, so it looks like any other HttpResponseError.

Proposed fix: [LLM provider Python SDKs] 403 permission comparison: PermissionDeniedError (openai/anthropic) vs genai ClientError 403 PERMISSION_DENIED vs Bedrock AccessDeniedException vs plain azure
Recommended action: Classify 403 by (status_code, provider error code) — e.g. err.response['Error']['Code']=='AccessDeniedException' for Bedrock, err.status=='PERMISSION_DENIED' for genai, err.status_code==403 for azure/mistral — and surface an entitlement/IAM action instead of retrying or failing over blindly.
