Introducing Z.AI GLM-Image on WaveSpeedAI

The landscape of AI image generation just got more exciting. WaveSpeedAI is proud to announce the availability of Z.AI GLM-Image, a groundbreaking 16-billion parameter text-to-image model that’s redefining what’s possible in AI-generated imagery—particularly when it comes to rendering text and knowledge-dense content with unprecedented accuracy.

What is GLM-Image?

GLM-Image represents a significant departure from conventional image generation approaches. Developed by Zhipu AI (Z.AI), this model employs a revolutionary hybrid architecture that combines a 9-billion parameter autoregressive language model with a 7-billion parameter diffusion decoder. This dual-engine design allows GLM-Image to excel where other models struggle: generating images with precise text rendering and complex information layouts.

The autoregressive component, built upon the proven GLM-4-9B foundation, handles instruction understanding, semantic reasoning, and overall image composition. Meanwhile, the diffusion decoder—equipped with a specialized Glyph Encoder—transforms these semantic representations into high-fidelity visuals with remarkably accurate text rendering.

Key Features

Superior Text Rendering Accuracy GLM-Image achieves a Word Accuracy score of 0.9116 on the CVTG-2K benchmark, dramatically outperforming competitors. On the LongText-Bench leaderboard, it scored 0.9524 for English and an impressive 0.9788 for Chinese text rendering—ranking first among open-source models across eight different scenarios including signs, posters, and dialogue boxes.

Knowledge-Intensive Generation Need infographics, presentation slides, or technical diagrams? GLM-Image excels at generating visuals that require both semantic understanding and precise information display. The model understands context, hierarchy, and layout in ways that pure diffusion models simply cannot match.

Strong Prompt Understanding Thanks to its autoregressive foundation derived from the GLM-4 language model, GLM-Image accurately interprets detailed prompts and generates images with high fidelity to your descriptions. The model reasons about objects, relationships, and spatial arrangements before generating pixels.

Flexible Sizing Options Generate images at your required dimensions with custom width and height controls. Whether you need square social media posts, vertical stories, or wide banner graphics, GLM-Image adapts to your specifications.

Built-in Prompt Enhancement Not sure how to craft the perfect prompt? Enable the prompt expansion feature and let GLM-Image’s built-in LLM automatically enhance your descriptions for better generation results. This is especially useful when starting with simple concepts that need more detail.

Multiple Output Formats Choose between JPEG for smaller file sizes ideal for web use, or PNG for lossless quality when you need pristine graphics with potential transparency requirements.

Real-World Use Cases

Marketing and Advertising Create professional promotional materials with accurate brand names, taglines, and product descriptions rendered directly in your images. No more post-processing to add text—GLM-Image handles typography as part of the generation process.

Social Media Content Generate engaging visuals for posts, stories, and ads with embedded text that actually looks professional. Quote graphics, announcement posts, and branded content have never been easier to produce.

Educational Materials Develop infographics, explainer diagrams, and educational posters where text clarity is paramount. GLM-Image’s exceptional performance with information-dense layouts makes it ideal for visualizing complex concepts.

Presentation Graphics Generate slide-ready visuals, data visualization mockups, and presentation backgrounds with integrated text elements. The model understands heading hierarchies and information card layouts.

Product Visualization Create mockups, packaging concepts, and product imagery where brand names and descriptions need to appear naturally within the scene.

Concept Art and Ideation Rapidly visualize ideas for creative projects with the confidence that any text elements in your concepts will render clearly and legibly.

Getting Started on WaveSpeedAI

Using GLM-Image on WaveSpeedAI is straightforward. Here’s how to generate your first image:

import wavespeed

output = wavespeed.run(
    "z-ai/glm-image/text-to-image",
    {
        "prompt": "A professional business infographic about sustainable energy, featuring clear statistics and modern design"
    },
)

print(output["outputs"][0])

For more control over your generations, you can specify additional parameters:

import wavespeed

output = wavespeed.run(
    "z-ai/glm-image/text-to-image",
    {
        "prompt": "A vibrant movie poster for a sci-fi film titled 'STELLAR DAWN' with dramatic lighting and futuristic typography",
        "width": 1024,
        "height": 1536,
        "enable_prompt_expansion": True
    },
)

print(output["outputs"][0])

Why WaveSpeedAI?

Running a 16-billion parameter model typically requires either a single GPU with more than 80GB of memory or a multi-GPU setup—infrastructure that’s expensive and complex to maintain. With WaveSpeedAI, you get:

  • No Cold Starts: Your requests process immediately without waiting for model loading
  • Fast Inference: Optimized infrastructure delivers results quickly
  • Simple Pricing: Just $0.12 per image, regardless of size or output format
  • REST API Access: Integrate GLM-Image into your applications with standard HTTP requests
  • No Infrastructure Hassles: Skip the GPU procurement, maintenance, and scaling challenges

Conclusion

Z.AI GLM-Image represents a genuine advancement in text-to-image generation, particularly for applications requiring accurate text rendering and knowledge-intensive content. Its hybrid autoregressive-diffusion architecture delivers capabilities that pure diffusion models struggle to match, making it an essential tool for anyone creating visuals with integrated typography.

Whether you’re building marketing materials, educational content, or creative projects, GLM-Image on WaveSpeedAI gives you access to state-of-the-art image generation without the infrastructure complexity.
