Cons
- -Processing complex documents with advanced features may require significant computational resources
- -Limited information available about performance benchmarks and processing speed for large document batches
- -Requires GPU resources due to 7B parameter model, making it computationally intensive and potentially expensive to run
- -May require multiple retries for some documents to achieve optimal results
- -Limited to image-based document formats (PDF, PNG, JPEG) and requires technical expertise for setup and optimization
