--- title: ERNIE-Image | Runware Docs url: https://runware.ai/docs/models/baidu-ernie-image description: General-purpose 8B text-to-image model with strong instruction following, text rendering, and structured layout control --- # ERNIE-Image ERNIE-Image is Baidu's 8B text-to-image model built on a single-stream Diffusion Transformer architecture. It is designed for strong prompt adherence, reliable text rendering, and structured visual generation, making it well suited to posters, comics, storyboards, multi-panel layouts, and other workflows where content accuracy and composition matter as much as aesthetics. The standard model emphasizes stronger general-purpose capability and instruction fidelity, typically running at around 50 inference steps. - **ID**: `baidu:ernie-image@0` - **Status**: live - **Creator**: Baidu - **Release Date**: April 15, 2026 - **Capabilities**: Text to Image, Checkpoint ## Pricing Pricing is highly dependent on number of parameters. The most significant cost multiplier is the use of promptEnhance(settings.promptEnhance) with an average price increase of 178%. Cost also scales approximately linearly with step count, baseline in use cases is 30 steps. - **1024x1024**: `$0.0109` - **2048×1024**: `$0.0160` ## Compatibility & Validation `acceleration` cannot be used with `acceleratorOptions`. --- `width` and `height` must be used together. ## Request Parameters **API Options** Platform-level options for task execution and delivery. ### [taskType](https://runware.ai/docs/models/baidu-ernie-image#request-tasktype) - **Type**: `string` - **Required**: true - **Value**: `imageInference` Identifier for the type of task being performed ### [taskUUID](https://runware.ai/docs/models/baidu-ernie-image#request-taskuuid) - **Type**: `string` - **Required**: true - **Format**: `UUID v4` UUID v4 identifier for tracking tasks and matching async responses.
