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.
