DeepSeek backend notes

This document captures backend-specific constraints that affect auditability.

Key point

Providers differ in:

• supported parameters (temperature, max tokens),
• determinism guarantees,
• error modes and rate limits.

The system’s contract is defined in terms of recorded metadata and artifacts, not in terms of provider behavior.

Practical guidance

• Record model_metadata faithfully (provider/model/temperature/max tokens).
• Treat provider errors as operational failures (execution_error or resource_exhaustion) depending on the failure mode.
• Do not claim replayability when sampling is enabled.
