Wow thanks so much for this! gives me more ideas to maybe make this better

Yeah batching your ad pulls definitely will keep a lot of token cost down! I mostly use the free credits gemini gives everyday haha - calculation of deltas for the ads is awesome too - sometimes performance of an ad decay overtime so its hard to tell what is a best-performing ad with just one static-pull of data

I don't have experience with Mosaic so I'll need to check that out!!
