What is ERNIE 4.5 VL API?

ERNIE 4.5 VL is part of Baidu’s ERNIE 4.5 family, a suite of multimodal models capable of interpreting complex data across multiple modalities. The VL variant specifically merges vision and language processing into a unified framework, allowing the model to analyze images, comprehend text, and generate detailed responses that connect both modalities. This model is suitable for applications ranging from interactive visual Q&A and content generation to document interpretation and visual reasoning. As an open-source solution under the Apache 2.0 license, it offers broad flexibility for research, development, and commercial applications.

Why ERNIE 4.5 VL Stands Out

ERNIE 4.5 VL combines cutting-edge multimodal reasoning with practical deployment flexibility. It offers open-source accessibility under Apache 2.0, a scalable architecture that ranges from efficient 28B models to high-capacity 424B models, and the ability to handle extremely long contexts for complex tasks. Its ecosystem includes tools and frameworks that accelerate development and integration, making it one of the most versatile solutions for vision-language AI available today.

ERNIE 4.5 VL 424B A47B

Activated parameters per token: ~47B
Architecture: MoE with modality‑isolated routing and high‑capacity expert layers
Tailored for high‑precision multimodal reasoning at scale.

Multimodal understanding

Joint processing of text prompts and images for grounded Q&A, captioning, retrieval-augmented reasoning and visual explanation.
Robust document and chart analysis: extraction of structure, trends, and insights from PDFs, reports, infographics and UI screenshots.

Advanced reasoning

Thinking mode with explicit multi-step reasoning over visual content, including zooming into regions, cross-referencing elements and performing symbolic reasoning (e.g., math over charts).
Strong performance on STEM-style tasks that integrate equations, diagrams and textual descriptions.

Multimodal Q&A and assistants

Knowledge assistants answering questions based on uploaded images, diagrams, dashboards, or scanned documents.
Technical support bots that read UI screenshots, error dialogs, schematics or machine photos to guide troubleshooting and repair workflows.

Use cases

Image, document, and chart understanding are documented use cases for ERNIE 4.5 VL 424B A47B, including visual reasoning and visual question answering.

It is also documented for cross-modal reasoning, with the model trained on text and image data to handle tasks that combine textual and visual information.

The model is documented as suitable for reasoning-centered multimodal tasks, with strong performance on benchmarks such as MathVista, MMMU, and VisualPuzzle.

It is also documented for perception-focused visual tasks, with good results on datasets such as CV-Bench and RealWorldQA.
