Price Estimate for Bedrock, is this correct?

Hi Joe, Based on the information provided, it seems your calculations for the estimated costs of using Amazon Bedrock's with RAG are correct. The key points are:

• For Titan Express : You estimated 4,000 input tokens and 27,000 output tokens per month. The aprox. pricing of only $0.05 per month for these usage levels.
• For Titan Text Embedding: You estimated a knowledge base of 40,000 tokens. The aprox. pricing of $0.005 per month.

It does seem that for the modest prototype you are considering, the costs would be effectively negligible. Your assumptions and calculations appear to be sound.

A few additional points to consider:

• The pricing for Amazon Bedrock is based on a pay-as-you-go model, so the costs will scale linearly as your usage increases.
• There are also charges for model customization, if you plan to create custom models beyond the pre-trained foundation models.
• It's always a good idea to monitor your actual usage and costs once you start using the service, as the pricing can change over time.

I suggest to reach out to AWS Support if you have any other questions about estimating or managing your costs further for the prototype.
