Most have discovered that the resulting DNG file size from AI Denoise is approximately 4 times that of the original raw. ex) Sony A1 50mb photo run thru AI Denoise resturns a ~200b DNG. This maybe fine for those with only a few photos run thru Denoise but for many it quickly starts to consume a massive amount of drive space. I tested taking the DNG into Photoshop then saving as TIFF with no compression and the resulting files size was back to 57mb.
There needs to be an option in AI Denoise to have it internally create its output as a TIFF.
