Ideogram 4 - Ideogram's Open-Source Text-to-Image Generation Model

What Is Ideogram 4

Ideogram 4 is Ideogram's first open-source text-to-image generationmodel, with 9.3 billion parameters, trained from scratch rather than fine-tuned based on existing models. The model is designed for high-quality image generation, with outstanding performance especially in design, marketing graphics, logos, posters, advertisements, and social media visual content. The model supports a structured JSON prompt interface, features industry-leading multilingual text rendering capabilities, deep language understanding, explicit bounding-box layout and palette control, and can natively generate 2K resolution images.

Ideogram 4's Main Features

• Accurate Text Rendering: Accurately generates signs, titles, logos, watermarks, and multi-line text within images.
• Structured JSON Prompt System: Precisely describes layout, style, lighting, color, fonts, and object positions through JSON.
• Bounding-Box Layout Control: Supports placing subjects and text in specific areas of the image for precise composition.
• Palette Control: Supports color control through hexadecimal color values.
• Multi-Aspect-Ratio Native Generation: Supports multiple aspect ratios from square to ultra-wide banners, with native 2K resolution output.
• Multilingual Support: Has best-in-class multilingual text rendering capabilities.

Ideogram 4's Technical Principles

• Single-Stream Diffusion Transformer Architecture: Ideogram 4 uses a single-stream Diffusion Transformer (DiT) as its core generation architecture, equipped with a vision-language model (VLM) text encoder, enhancing understanding of complex prompts and achieving more precise image generation and text-semantic alignment.
• Trained from Scratch Rather Than Fine-Tuned: The model has 9.3 billion parameters and is trained completely from zero, not fine-tuned based on any existing image model. Its independent training path has allowed it to form a unique capability boundary in design-oriented image generation, focusing on native generation of high-quality visual content.
• Structured JSON Prompt System: The model introduces a structured JSON prompt interface, supporting users in describing layout, style, lighting, color, fonts, and object positions in a precise and controllable way. Compared with natural language prompts, the JSON format provides more fine-grained control and reduces the randomness of prompt engineering.
• Bounding-Box Layout and Palette Control: The technology supports explicit bounding-box layout control, allowing subjects and text to be precisely placed in specific areas of the image; it also supports palette control through hexadecimal color values, enabling precise customization of image colors.

How to Use Ideogram 4

• Online Experience: Directly visit Ideogram official website to generate images online.
• Local Deployment: Download the inference code and model weights from GitHub, and use the Diffusers library to load and run.
• JSON Prompts: Input prompts in structured JSON format to precisely control layout, style, and color.
• Choose a Quantized Version: Choose the nf4 (CUDA, supports Diffusers) or fp8 (all platforms) version according to hardware.

Ideogram 4's Core Advantages

• Open-Source Leadership: Far ahead in the Design Arena open-source model leaderboard, with an Elo score of 1285, far surpassing the second place.
• Design Frontier: In the overall ranking, it is second only to closed-source models such as GPT Image 2,GPT-Image-1.5 and Gemini 3.1 Flash, placing it at the forefront of the design field.
• Precise and Controllable: The JSON prompt system provides more precise image control than natural language.
• High-Resolution Native Output: Directly generates clear 2K images without the need for upscaling.
• Non-Commercial Friendly Open Source: Inference code and weights are fully public, encouraging innovation in the research community.
