Frequently Asked Questions (FAQ)

Q1. Which is better — Midjourney or DALL-E 3? A. Midjourney v7 has the edge in image quality and artistry, but if you already subscribe to ChatGPT Plus, DALL-E 3 is available at no extra cost. Midjourney is recommended for professional creators; DALL-E 3 within ChatGPT is recommended for casual users.

Q2. Can I use images created with AI image generation tools commercially? A. It depends on the tool. Adobe Firefly fully allows commercial use. Midjourney allows commercial use on paid plans (Pro plan and above is also allowed for businesses). DALL-E 3 and Stable Diffusion generally allow commercial use. However, Adobe Firefly is the safest option to minimize copyright dispute risk.

Q3. What GPU is good for getting started with Stable Diffusion? A. For beginners, the NVIDIA RTX 4060 (8GB VRAM) offers the best value. With the 4060, generating an SD 3.5 image takes about 10–20 seconds. 12GB VRAM or more (e.g., RTX 4070) allows faster generation and support for higher resolutions.

Q4. Which tool can accurately embed Korean text in AI images? A. As of 2026, Ideogram is the best for inserting Korean text. Midjourney and DALL-E 3 often produce garbled or inaccurate characters when Korean text is requested. Ideogram is strongly recommended for creating thumbnails or posters that include Korean text.

Q5. Can I get good images even if I'm not good at writing prompts? A. DALL-E 3 internally auto-enhances prompts, so speaking naturally as if in a conversation still yields great results. Midjourney also generates excellent images from simple word combinations. With Stable Diffusion, your ability to write detailed prompts directly affects output quality.

Q6. How do I specify a particular style (watercolor, photo, etc.)? A. In Midjourney, use the --style and --stylize parameters along with the Reference Image feature. For DALL-E 3, simply describe it in natural language, like "in a watercolor style." In Stable Diffusion, you can install LoRA models to precisely control specific styles.

Q7. How can I generate high-quality images for free? A. Bing Image Creator (powered by DALL-E 3, free) is the best free option for quality. Ideogram's free plan (25 credits/day) is also excellent. Installing Stable Diffusion locally on your PC allows unlimited free generation as long as you have a GPU.

Q8. What new features in AI image generation are worth watching in 2026? A. The convergence of video generation and AI is receiving the most attention. Text-to-video tools like Sora, Kling, and Runway Gen-3 have advanced rapidly. On the image generation side, consistent character generation (Character Consistency) and real-time image editing are the key trends for 2026.
