The gap in generative AI
Text-to-image models like Midjourney, DALL-E, or Nanobanana Pro represent a breakthrough in digital art. They are incredible at generating a surreal concept art or a stock photo replacement.
However, for businesses, they fail at one critical task: Design.
The problem?
Text-to-image models generate flat raster images. The text they generate is often Hallucinated, buttons are just colored rectangles you can't click, and you cannot move a single element. If you need to change a headline, you have to regenerate the entire image and hope for the best.
The Solution
The Large Design Model. By treating design as a structured system of components rather than a grid of pixels, an LDM bridges the gap between chaos and control.

Why the industry needs LDM
Editable & Layered
Real design work is iterative. Marketing teams need the ability to swap a product image or rewrite a headline without breaking the composition. LDMs generate layers, making this instant.
Brand Consistent
Text-to-image models struggle to perfectly replicate a logo or a specific hex code because they dream the image. An LDM constructs the design using your exact brand assets.
Any Size
There is no one size fits all. Text-to-image models are fixed to specific aspect ratios. Text-to-design outputs generate in any size, from a mobile banner to a billboard to a custom size such as 328 x 244.
Use cases for LDM
High-CTR Display Ads
Generate hundreds of variations for A/B testing. Because the text is real, the LDM allows for instant copy swapping.
Social Media Content
Feed the LDM a blog post, and it generates a summary. It understands the essence of content.
Eye-catching Thumbnails
Describe a YouTube thumbnail for a crypto channel, and the LDM builds the composition, key visuals, and headlines in the correct positions.
The evolution of LDMs - Sivi's journey
Sivi has been the Large Design Model category creator.
Sivi Gen-1
The first text-to-design model. Proved that AI could lay out elements based on a text prompt. Launched on 6 Jun, 2023 on Product Hunt and emerged as the #1 product.
Sivi Gen-2
Introduced "Style Cards" and "Composition Guides," giving users control over the aesthetic direction of the LDM. Launched in 2024, 10 months from Sivi Gen-1.
Incremental releases: Sivi Gen-2E and Sivi Gen-2.5.
Sivi Gen-3
The component-based Large Design Model with agentic reasoning to create editable, on-brand designs. Sivi Gen-3 is coming soon in Q1 2026.
Common questions about LDM
What is a Large Design Model (LDM)?
A Large Design Model (LDM) is a type of generative AI trained to create structural graphic designs (ads, email headers, banners, social posts) rather than just flat images. It understands the relationships between visual elements.
How is LDM different from LLM or Image Models?
While LLMs (Large Language Models) generate text and image models generate raw pixels, LDMs generate design structure combining text, vectors, and images into a cohesive, editable design.
What is the difference between text-to-image and text-to-design?
Text-to-image creates a picture of a design (like a photograph of a poster). Text-to-design creates the actual digital file of the poster (with separate layers for text, background, and logo).
Is Sivi an LDM?
Yes, Sivi is the world's first dedicated Large Design Model. It natively generates layered, vector-based designs from text prompts.
What is the difference between an LDM and an LLM?
An LLM processes linguistic tokens (words) to predict the next word. An LDM processes visual tokens (components, styles, spacing) to predict the next design element.
Can an LDM generate editable text?
Yes. Unlike image models that generate "gibberish" pixels that look like text, an LDM places actual text boxes with real fonts that you can edit, copy, and paste.
Is text-to-design the same as text-to-image?
No. Text-to-image creates a static raster file. Text-to-design creates a dynamic, multi-layered composition.
What is the best Large Design Model available?
Sivi is currently the leading LDM, offering the ability to specific brand guidelines, generate designs, and export to editable formats.
Do Large Design Models follow brand guidelines?
Yes. Because they understand "components" rather than just pixels, LDMs like Sivi can be instructed to strictly use your specific font files, color codes, and logo rules.
Experience the power of LDM.
Start generating real designs rather than wrestling with prompts that give you unusable images.
