AI Prompt Syntax: Midjourney vs DALL-E vs SD

Side-by-side comparison of prompt syntax differences across all major AI tools. Reference guide for switching between platforms.

⏱️ 9 min read

Every AI creative platform speaks its own "dialect." What works beautifully in Midjourney produces garbage in Stable Diffusion. DALL-E wants natural language; Stable Diffusion wants keyword soup with parentheses. Suno's music prompts follow completely different rules than image generators. If you're switching platforms or using multiple tools, mismatched syntax wastes generations and burns through credits.

This reference guide shows you exactly how to translate concepts across platforms. Need to specify aspect ratio? Midjourney uses --ar 16:9, DALL-E wants "in landscape format", Stable Diffusion needs width/height parameters. Want to emphasize a style? Each platform has different syntax for weighting and emphasis. Use this as your quick-reference cheat sheet when adapting prompts between tools.

--stylize [0-1000]

Artistic interpretation strength (default: 100)

--chaos [0-100]

Variation amount between results

--quality [.25|.5|1|2]

Rendering quality/time (default: 1)

--no [items]

Things to avoid (e.g., --no hands, text)

--iw [0-2]

Stable Diffusion Prompt Weighting Syntax

▼

Emphasis with Parentheses:

(word)

1.1x emphasis (slight increase)

((word))

1.21x emphasis (1.1²)

(((word)))

1.33x emphasis (1.1³)

(word:1.5)

1.5x emphasis (explicit weight)

[word]

0.9x de-emphasis (decrease importance)

Example Prompt:

a ((beautiful woman)), highly detailed face, (blue eyes:1.3), long flowing hair, [background], photorealistic, 8k

Common mistake: Over-weighting (above 1.5) often creates artifacts. Start subtle.

(masterpiece:1.2), (best quality:1.3), 8k, RAW photo, highly detailed, sharp focus, professional lighting, intricate details, absurdres

Remember: Quality keywords work differently on each platform. Test what works for your use case.

How to Adapt Prompts Between Platforms

The syntax differences above reveal a deeper truth: each AI platform has its own "personality" that responds to different prompting styles. Midjourney loves concise, poetic descriptions with artistic references. DALL-E 3 prefers natural language explanations like you're talking to a human. Stable Diffusion wants keyword-dense prompts with explicit technical details. When migrating a prompt between platforms, don't just copy-paste — translate the intent.

Translation strategy: Start with your subject and core concept (this stays the same). Then adapt the style descriptors, quality keywords, and technical parameters to match the target platform's syntax. For example, a Midjourney prompt like majestic mountain landscape, golden hour, dramatic clouds --ar 16:9 --stylize 300 becomes A majestic mountain landscape photographed during golden hour with dramatic cloud formations, in wide landscape format, high quality and extremely detailed for DALL-E 3. The concept is identical, but the expression matches each platform's language. Practice this translation with our Prompt Generator, and read platform-specific guides: Midjourney Prompts Guide, Stable Diffusion Prompts, and AI Music Prompts Guide.
