| # ReCAP-8B-Instruct | |
| ReCAP-8B-Instruct is a vision-language model fine-tuned from | |
| [Qwen/Qwen3-VL-8B-Instruct](https://huggingface.co/Qwen/Qwen3-VL-8B-Instruct), designed to enable robust CAPTCHA solving within native GUI agents while preserving general GUI interaction capabilities. | |
| This model is introduced in β[CAPTCHA Solving for Native GUI Agents: Automated Reasoning-Action Data Generation and Self-Corrective Training](https://arxiv.org/abs/2603.23559)β, accepted at ICML 2026. | |
| --- | |
| ## π Overview | |
| ReCAP-8B-Instruct extends a general-purpose GUI agent with CAPTCHA-solving ability by learning from structured reasoning-action trajectories. | |
| It operates end-to-end: | |
| - Input: raw screenshots | |
| - Output: reasoning + executable GUI actions (click, type, drag) | |
| --- | |
| ## β¨ Key Features | |
| - Unified agent: Handles both CAPTCHA and general GUI tasks | |
| - Reasoning-action modeling: Learns both decisions and execution | |
| - Self-correction: Improves robustness by learning from failures | |
| - Efficient interaction: Generates multiple actions per step | |
| --- | |
| ## π§ Capabilities | |
| Supports diverse CAPTCHA types: | |
| - Text / OCR | |
| - Icon selection & matching | |
| - Image grid reasoning | |
| - Slider / drag tasks | |
| - Multi-step interaction challenges | |
| Core skills: | |
| - Visual understanding | |
| - Spatial reasoning | |
| - Continuous control | |
| - Multi-step planning | |
| --- | |
| ## π Performance | |
| - ~78.6% success rate on synthetic CAPTCHA benchmark | |
| - 14.50 percentage-point average improvement over Qwen3-VL-8B-Instruct across 26 real-world CAPTCHA types in zero-shot evaluation | |
| - Strong improvements on interaction-heavy tasks (e.g., slider, image grid) | |
| - Maintains competitive performance on general GUI benchmarks | |
| --- | |
| ## β οΈ Ethical Considerations | |
| This model is released for research purposes only. | |
| It is intended to study and improve the robustness of human-verification systems, not to bypass them. |
