## 📋 Model Description

**AdaReasoner-7B** is a vision-language model trained with dynamic tool orchestration capabilities for iterative visual reasoning. This model is AdaReasoner-7B-Non-Randomized.


We provide three variants of AdaReasoner-7B, each optimized for different use cases:

| Model | Description | Hugging Face |
|------|-------------|--------------|
| **AdaReasoner-7B-Randomized** | Trained with the *adaptive learning* method, enabling strong generalization to **unseen tools and tasks**. Designed for open-ended and evolving tool environments where adaptability is required. | [🤗 Link](https://huggingface.co/AdaReasoner/AdaReasoner-7B-Randomized) |
| **AdaReasoner-7B-Non-Randomized** | Trained **without adaptive learning**, providing **more stable and reliable performance on known tools and tasks**, but limited generalization to unseen tools or task settings. | [🤗 Link](https://huggingface.co/AdaReasoner/AdaReasoner-7B-Non-Randomized) |
| **AdaReasoner-VSP-7B** | Task-specialized model trained **exclusively on the Visual Spatial Planning (VSP) task**, achieving strong performance on VSP benchmarks but not intended for cross-task generalization. | [🤗 Link](https://huggingface.co/AdaReasoner/AdaReasoner-VSP-7B) |



**Key Differences:**
- **Randomized**: Trained with adaptive learning method, enabling zero-shot generalization to novel tools and task configurations
- **Non-Randomized**: Trained without adaptive learning, offering more predictable behavior on familiar tools but lacking generalization
- **VSP-7B**: Task-specific model fine-tuned exclusively on Visual Spatial Planning (VSP) benchmarks for optimal performance on navigation tasks

## 🚀 Quick Start

AdaReasoner-7B can be deployed for single-turn inference using standard inference frameworks such as vLLM.
However, AdaReasoner is a tool-planning model whose full capabilities require interaction with an external tool environment.
To fully evaluate or utilize its tool-planning behavior, we recommend using [AdaEval](https://github.com/ssmisya/AdaReasoner/tree/main/tool_server/tf_eval) provided in our repository for batch inference and evaluation, or trying the [Demo](https://github.com/ssmisya/AdaReasoner/tree/main/tool_server/tf_eval/demo) interface for interactive, single-instance GUI-based reasoning.

## 🎯 Capabilities

The model supports a diverse set of visual reasoning tasks, covering both structured reasoning and open-ended visual understanding:
-	**Visual Spatial Planning**
Navigation and verification tasks based on grid-world environments (VSPO and VSP), evaluating fine-grained spatial perception, multi-step path planning, and safety verification under out-of-distribution map configurations.
-	**Compositional Visual Reasoning (Jigsaw)**
Image reconstruction from shuffled patches (Jigsaw-COCO and BLINK-J), testing local–global consistency, part–whole reasoning, and visual compositional understanding.
-	**GUI Question Answering (GUIQA)**
Fine-grained reasoning over GUI screenshots, including interactive webpage understanding (GUIChat) and agent-centric UI reasoning from WebMMU (Agentic Action subset), emphasizing element grounding, action planning, and multi-step inference.
-	**General Visual Question Answering (General VQA)**
Open-ended visual reasoning beyond structured settings, evaluated on V* and HRBench, focusing on fine-grained visual search, attribute recognition, spatial relationship reasoning, and robustness to high-resolution, complex real-world scenes.

## 🛠️ Tool Integration
