Bedrock prompt cache models

Hi,

Page https://docs.aws.amazon.com/bedrock/latest/userguide/prompt-caching.html give the full list of supported model:

Nova comes at the top of this table but use scroll bar on the right to see the other models.

Based on the most recent information available, the Amazon foundation models that currently support prompt caching are:

1. Amazon Nova Micro
2. Amazon Nova Lite
3. Amazon Nova Pro

It's important to note that there appears to be a discrepancy in the information you've found. While the code example you referenced suggests that Amazon Titan Text Premier might support prompt caching, the official documentation indicates that only the Amazon Nova models currently have this capability.

As for the Anthropic models, Claude 3.5 Haiku and Claude 3.5 Sonnet v2 also support prompt caching.

Given the conflicting information, it's best to rely on the most recent official documentation. The support for prompt caching may be evolving, and features can change over time. If you need the most up-to-date and accurate information, I recommend checking the latest Amazon Bedrock documentation or contacting AWS support directly.

It's worth noting that prompt caching is a relatively new feature in Amazon Bedrock, and its availability may be expanding to more models over time. The feature is designed to significantly reduce costs and latency for supported models by caching frequently used prompts across multiple API calls.
