Model Details

Model Details

Seedream 4.5 is a state-of-the-art text-to-image model developed by ByteDance, designed to generate stunning, high-fidelity visuals from descriptive text prompts. Built on an advanced, unified architecture, it excels at understanding complex instructions, enabling creators to craft detailed scenes, unique visual styles, and precise compositions effortlessly.

You can run this model directly via the application UI. Simply enter your descriptive prompt, choose your desired output size, and securely download your generated images using the built-in interface components.

**Features** * **Precise Text Rendering:** Reliably generates legible, clearly visible typography directly within your images based on specific prompt instructions. * **Stylistic Versatility:** Seamlessly adapts to distinct photographic styles, specific camera angles (such as selfies or wide shots), and nuanced post-processing effects (like motion blur or overexposure). * **High-Resolution Output:** Capable of generating vibrant, detailed images in various dimensions, supporting automated 2K and 4K optimizations for pristine quality.

**What it’s good at** * Creating highly stylized, photorealistic, or imaginative artistic imagery with intricate details. * Following complex, multi-layered prompts that combine specific character traits, dynamic environmental settings, and text placements simultaneously. * Generating dynamic scenes that require highly specific framing, lighting, or unique visual treatments.

**Tips** * Be as descriptive as possible. Specify the lighting, camera angles, emotional tone, and subject focus to guide the model accurately. * When adding text to your generation, explicitly place the exact phrase in quotation marks within your prompt and describe its placement and typography (e.g., *The text "Hello World" written in crisp lettering at the top*). * Use the app's UI to experiment with different detailed descriptions, and easily download multiple variations to find the perfect composition.

To run via ModelRunner JavaScript client: ```javascript import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe("bytedance/seedream-v4.5/text-to-image", { input: { prompt: "A selfie of a happy cat at twilight near the Eiffel Tower, holding a piece of baklava. The photo has slight motion blur and is slightly overexposed. The text \"Seedream 4.5\" is clearly written at the top.", image_size: "auto_2K" }, });
