Superseded by Nano Banana 2 (Gemini 3.1 Flash Image). It no longer holds a current-board position.
This category board uses only published catalogue and deployment facts. It does not infer media-generation quality or compare incompatible media-unit prices.
This is a discovery ordering, not a capability benchmark. Category-compatible public evaluation evidence must be added before ModelCap can publish a media-quality rank.
Not yet published: a pinned repository revision, the architecture and model type, a parameter count, safetensors weight metadata, the base model it derives from, a declared licence, a link to the licence terms, admitted benchmark results, results across several capability areas, results from more than one source, a confident match to its benchmark entries, pinned evaluation dataset versions.
A metadata completeness and deployability index—not a safety certification, quality grade, or production-readiness claim.
