What
Bedrock input tokens now include tokens read from and written to the prompt cache, for Converse, ConverseStream, and Claude InvokeModel (streamed or not).
Why
Bedrock and Anthropic report only uncached prompt tokens as input, so cached calls showed far fewer input tokens than were used.
Extracted from #26118.
