OCR: speed, accuracy, and memory in vision models
A comparison published on November 11, 2025 evaluated two model sizes and formats for OCR and structured extraction, reporting trade-offs in speed, accuracy, and memory use.

What happened and what to do
The comparison published on November 11, 2025 evaluated 8B BF16 and 30B quantized Q8 vision models for OCR and structured data extraction. The author reported that the larger quantized model was faster and more accurate, but used more memory. The findings highlight trade-offs among model size, quantization, speed, accuracy, and memory resources.
A company can test these options on its own documents and quality criteria, while measuring latency and memory in the target environment. An evaluation pipeline can record results by document type and monitor errors, operating costs, and performance, helping select a configuration without assuming one model suits every case.
How the consultancy can help
Wendelmaques can assess the document workflow and its accuracy, latency, and memory requirements, define an evaluation using representative data, and implement the OCR, monitoring, and operations pipeline on the client’s infrastructure.
