# Topaz CGI IMAGEFeaturedtopaz-cgi-upscale-image CGI is the tier of Topaz Labs’ Gigapixel precision upscaler built for rendered and illustrated images rather than photographs, enlarging up to 4x while keeping flat colour, clean lines and hard edges intact. Best for game art, concept work and CG renders. Best for Rendered art, game assets and concept work, Illustration and CG that should stay clean No parameters published for this model This model's inference form declares no fields, so the request body below is documented as an empty object — any input asset it needs is not described by the published schema. Fetch the authoritative form at runtime with [Get a model's inference input schema](/docs/v2/rest-api/operations/getinferenceschema).
