Chocoberry Avatar Bakeoff Round 2

Cheap stylized models only, with Nano Banana in the mix.

This round sticks to Chocoberry’s nonrealistic lane and tests four lower-cost image paths across the same three characters: Riverflow Fast, Riverflow Fast Preview, Gemini 2.5 Flash Image (Nano Banana), and GPT-5 Image Mini. Prompts are all stylized, but varied a bit to explore luminous, ornate, vibrant, and graphic directions.

Variant	Model	Count	Total Cost

OpenRouter price takeaway from this batch: Nano Banana was good, but not cheaper than Riverflow Fast here. Actual per-image averages in this run were about $0.0200 for Riverflow Fast, $0.0300 for Riverflow Fast Preview, $0.0388 for Nano Banana, and $0.0435 for GPT-5 Image Mini.
