Lumen vs Vivid vs Noir vs Glyph: Which Engine to Use

By MomentumTech Corporation · Updated June 24, 2026

Comparison of AI image engines

MomentumTech GPT ships four image engines, each tuned for a different job. Picking the right one is the fastest way to better results. Here is a simple guide.

Lumen — the all-purpose default

Your go-to for portraits, everyday images and editing photos you upload. If you are not sure which engine to use, start with Lumen.

Vivid — photoreal products & real estate

Built for crisp, accurate detail. Use Vivid for e-commerce product shots, catalog images and bright real-estate interiors where clean lines and true surfaces matter.

Noir — cinematic & stylized art

When you want mood, drama and a strong artistic point of view, reach for Noir. Great for posters, album art, moody portraits and concept visuals.

Glyph — designs with readable text

Most image models struggle with legible text. Glyph is purpose-built for it — logos, flyers, posters, ads and any design where the words must be clear.

Quick reference

Portrait or photo edit → Lumen. Product or property → Vivid. Cinematic art → Noir. Anything with text → Glyph. Still unsure? Let the studio auto-select based on your prompt.
