# Intended Use
|
108 |
+
|
109 |
+
This model is intended for:
|
110 |
+
|
111 |
+
* Document analysis and OCR from scanned images, PDFs, and camera input.
|
112 |
+
* Image-based question answering (e.g., educational content, diagrams, receipts).
|
113 |
+
* Math problem solving and LaTeX text generation from handwritten or printed math content.
|
114 |
+
* Long-context vision-text applications such as multi-slide document retrieval and dense information extraction.
|
115 |
+
* Multilingual OCR workflows for cross-lingual business documents and global data digitization.
|
116 |
+
* AI agents for mobile/robotic interaction through visual context.
|
117 |
+
|
118 |
+
# Limitations
|
119 |
+
|
120 |
+
* Performance may degrade on extremely noisy or low-resolution images.
|
121 |
+
* Not suitable for real-time inference on edge devices due to model size and memory demands.
|
122 |
+
* While multilingual, performance on low-resource or rare scripts may vary.
|
123 |
+
* Not optimized for high-speed processing of video streams in constrained environments.
|
124 |
+
* Contextual understanding depends on visual tokenization parameters; improper configuration may affect output quality.
|
125 |
+
* Outputs may occasionally include hallucinations or incomplete answers in long-context queries.
