Imagen 4 Fast
Google Imagen 4 — faster and more affordable
Imagen 4 Fast is Google's speed-optimised AI image generation tier, delivering Imagen 4's strong natural language understanding and photorealistic quality at faster generation speed and lower credit cost. It's the practical choice for teams running structured A/B creative tests, producing high volumes of social content, and iterating on creative directions before committing to final-quality output. On Xarith, Imagen 4 Fast sits alongside Standard and Ultra tiers so you can move from rapid iteration to final quality in the same session.
Google image quality at faster speed
Imagen 4 Fast retains Google's core image generation capabilities — accurate prompt following, good photorealism, and reliable scene composition — at faster generation speed and lower cost. For teams generating dozens of variants per session, the throughput advantage compounds significantly across a production workflow.
Practical for A/B creative testing
Generate multiple prompt variants, lighting setups, and compositional approaches quickly to identify the creative direction with the strongest potential. Once identified, promote the best concept to Imagen 4 Standard or Ultra for final-quality output. This two-stage workflow avoids wasting high-quality compute on concepts that won't perform.
