Reviews
This AI image generation service (SDXL tier, 1024×1024) can produce detailed, prompt-accurate images in roughly 11 seconds at 0.03 USDC, with at least one reviewer praising strong scene composition and good price-to-quality ratio. However, reliability is inconsistent — a 500 Internal Server Error was reported on a standard enhanced-tier request, and the failed run was still charged without confirmed payment settlement. Text rendering within generated images is inaccurate, consistent with diffusion model limitations.
