DeepSeek-OCR demonstrates a significant compression capability where 100 vision tokens can represent approximately 1000 text tokens with over 97% accuracy, suggesting a 10× compression ratio. This compression is possible due to the fundamental differences between vision and text tokens; vision tokens encapsulate much more information, such as words, layout, font style, and size, within a 64×64 pixel area, compared to text tokens that typically represent single words. Despite the varying information density, both vision and text tokens are mapped to the same 4096-dimensional space, which provides a rich representation for capturing semantic relationships. While text tokens go through a vocabulary space to reach this dimension, vision tokens undergo direct compression, making the process seamless and continuous without the need for vocabulary expansion. This approach highlights how vision tokens can efficiently compress and represent a substantial amount of information compared to text tokens.

The Retrieval Embedding Benchmark (RTEB) introduces a new standard for evaluating the retrieval accuracy of embedding models, addressing limitations found in existing benchmarks. RTEB employs a hybrid strategy that combines open and private datasets, aiming to provide a fair and transparent measure of models' generalization capabilities on unseen data. This approach helps mitigate overfitting by revealing performance discrepancies between open and private datasets, thereby encouraging robust model development. RTEB is designed with a focus on real-world applications, covering 20 languages and encompassing critical enterprise domains such as law, healthcare, code, and finance. It uses datasets that are large enough to be meaningful without being overly cumbersome for evaluation, and it employs NDCG@10 as the default metric for assessing search result quality. The benchmark is multilingual and domain-specific, supporting enterprise use cases and encouraging community involvement to expand language coverage and dataset variety.
