Retrieval updates the model context without changing weights. It would support rapidly updated source-backed answers, not pretrained models for ML experimentation.

Bedrock provides access to supported ready-to-invoke model families. That is useful for selecting a pretrained FM for API use, not pretrained models for ML experimentation.

Output token controls directly affect generated volume and per-call cost. Its primary purpose is unpredictable lengthy model output, not predictable high-volume model serving.

Request-based inference aligns charges with variable demand. It solves variable traffic without reserved capacity, not predictable high-volume model serving.

Prompt caching can reduce cost of recurring context portions where available. It would support reusable static prompt prefix cost, not predictable high-volume model serving.

Network distance and service placement contribute to observed request delay. Its primary purpose is geographically suitable serving latency, not regional data processing constraints.

Retrieval applications depend on the availability of both models and supporting data. It solves recovery of grounded data sources, not regional data processing constraints.

Redundancy and fault isolation reduce individual component outage impact. That addresses resilient access through local infrastructure failure, not regional data processing constraints.
