ServiceQuotaExceededException docs say you can resubmit later. Fix status: documented_behavior Misleading approaches: - Treating every 400 from Bedrock as a validation bug. - Assuming a 429 always means per-minute throttling. Unknowns: - Current idle-eviction window for imported models (not in fetched sources). Other error fragments: - The model specified in the request is not ready to serve inference requests. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/boto/botocore/develop/botocore/data/bedrock-runtime/2023-09-30/service-2.json (official_docs, unknown, documented_behavior): botocore Bedrock Runtime shapes: ServiceQuotaExceededException httpStatusCode 400 ("resubmit your request later"); ModelNotReadyException 429 ("AWS SDK will automatically retry the operation up to 5 times"); ModelStreamErrorException 424 ("Retry your request"); ThrottlingException 429. - https://github.com/aws-samples/bedrock-engineer/blob/main/docs/custom-model-import/README.md (official_docs, unknown, documented_workaround): AWS sample docs: "Model is not ready for inference" for imported models; wait minutes to tens of minutes and retry.
