I forgot about the continuous pre-training thing. How long and how much did they cost on Bedrock? I had tried to suggest continuous pre-training to my client but it seemed expensive and when I mentioned that he lost interest and just kept wanting me to do fine tuning. Also to clarify, did you do the continuous pre-training or RAG? And did you compare the efficacy of one or the other or both?
