AI Image Generators Comparison

Jun 25, 2025

Overview

The video reviews five leading AI image generators, explaining their features, free usage limits, and performance under similar testing conditions. A side-by-side comparison highlights strengths, weaknesses, and ideal use cases for each tool.

Rev (preview.rev.art)

  • Free account gives 100 initial credits and 20 daily credits, each image costs 1 credit.
  • Simple interface; no predefined styles, users must specify desired style in prompt.
  • Can enhance prompts for more detailed results; aspect ratio adjustable.
  • Supports generating up to eight images at once; “Instruct” lets users alter parts of an image.
  • Image-to-image feature copies aspect ratio but doesn’t use uploaded prompts.
  • Best at realistic close-up portraits, but struggles with faces at distance.

Runway

  • Known for video creation, but also provides image generation (≈15 free images).
  • Offers predefined styles, aspect ratio adjustment, aesthetic range, and reference images.
  • Reference images enable consistent character generation; can save and reuse named characters.
  • Can generate variations and turn images into videos.
  • Produces very consistent characters from references; good with complex prompts and real objects/brands.
  • Blocked some generations due to policy restrictions.

Google Image Generators (ImageFX & Wisk)

  • ImageFX requires VPN in some regions; allows style/effect keywords and seed locking for character consistency.
  • Detailed prompts and locked seeds help achieve similar characters.
  • Wisk adds support for object, environment, and style references; Imagin 4 model available.
  • Strong censorship, especially with images of people.
  • Realism and consistency vary; reference images less effective for exact character replication.
  • Struggled with complex hand prompts; otherwise offers generous free plans.

Ideogram AI

  • Provides 10 weekly credits; latest model offers higher quality at higher credit cost.
  • Users can browse and reuse others’ prompts/settings; aspect ratio and quality (render speed) adjustable.
  • “Magic prompt” enhances descriptions; negative prompts and advanced options are paid.
  • Faces look best when closer to the camera; issues with distant faces and multiple objects in complex scenes.

ChatGPT-4 (Image Generation)

  • Up to three free images per day; accepts prompts or reference images.
  • High image quality, but images often have a yellow tint unless color temperature is specified in prompt.
  • Consistency in realistic characters is limited; better suited for cartoonish or less-detailed faces.
  • Effective at close-ups and complex scenes; accuracy issues with distant faces/hands and real places.
  • Offers prompt-based workarounds for color cast issues.

Feature Comparison and Results

  • Best close-up portraits: Rev, Runway, Ideogram.
  • Best at hands: ChatGPT and Rev (but multiple attempts may be needed).
  • Complex scenes: Runway and ChatGPT provide most accurate and prompt-adherent images.
  • Real objects/places: Runway and Google limit real people images for policy reasons; all did well with places/brands except ChatGPT, which had lower fidelity for cityscapes.
  • Only Runway and Google allow consistent character generation via references; prompts alone are needed for ImageFX.

Summary & Conclusions

  • No perfect universal image generator; each tool excels in different scenarios.
  • Runway and Google tools are best for consistent characters; ChatGPT stands out for complex scenes with some limitations.
  • Free plans and feature sets vary; users should select based on personal needs and priorities.
