AI Models Behind Each Tool
Bing Image Creator runs on DALL-E 2 / DALL-E 3 — optimized for photorealistic compositions and realistic photo scenes.
ChatGPT uses DALL-E 3 with no visible watermark, making it one of the cleanest outputs in the free tier — limited by generation quota on the free plan.
Google Gemini uses Nano Banana Pro for image generation, integrated directly into the chat interface.
Adobe Firefly runs on Firefly Image Model 5 — one of the most powerful free-tier models, with built-in style controls.
Raphael AI uses FLUX.1-Dev — a high-quality open-weight model capable of both photorealism and artistic styles. Fully free, no login.
Krea.ai runs on FLUX.1 — same model family as Raphael AI, strong on photorealism. DeepAI runs on Stable Diffusion. Craiyon V3 produces more stylized, illustrative output.
