Base Model Information

openbmb/MiniCPM-V-4.6-Thinking is the reasoning-enabled variant of OpenBMB’s 1.3B-parameter MiniCPM-V-4.6 series. It uses SigLIP2-400M as the vision encoder and Qwen3.5-0.8B as the language backbone, supporting multimodal reasoning across text, image, and video inputs with up to 262K context length, and enabling explicit step-by-step reasoning for complex tasks.

Intended Use

• Multimodal Reasoning Research Studying reasoning behaviors across text, image, and video inputs.

• Evaluation & Benchmarking Testing multimodal model performance across structured reasoning tasks.

• Edge & Local Deployment Running compact multimodal systems efficiently on consumer hardware.

• Research Prototyping Experimenting with multimodal reasoning architectures and workflows.

Limitations & Risks

Important Note: This model inherits the behavior and characteristics of its base model.

• Reasoning Hallucinations Step-by-step reasoning may occasionally include incorrect or fabricated steps.

• Output Reliability Results should be verified before use in critical applications.

• Multimodal Constraints Performance depends on input quality, context length, and task complexity.

• Deployment Considerations High-resolution multimodal inference may require significant compute resources.
