Nitpick: RLHF and RLAIF provide preferences between candidate data from another source, they don't provide synthetic data themselves. Of course someone can train a model using synthetic data generated by another model, that's just not RLAIF.
And a serious issue: that's probably not copyright safe in the way Adobe wants.
Same pattern: - RHLF -> RLAIF using GPT4 - Firefly using Midjourney
When there's a "good enough" AI solution, the synthetic data will come from it.
