Google Imagen

Imagen 4 is Google's text-to-image model, strongest on photorealism and on rendering short text strings correctly — the failure mode where a sign or label comes out as plausible-looking gibberish is much rarer here than in most models.

Three tiers are available: Fast for iteration, standard Imagen 4, and Ultra for maximum fidelity. The quality gap between Fast and Ultra is real but not so large that Fast is unusable for finals.

Standard-tier pricing at 2 credits a generation, so the 100 free signup credits cover roughly fifty Imagen renders — enough to compare all three tiers on the same prompt before settling on one.
