AI is happening. The future is updating.LightOnOCR-3-1B
**Same architecture as LightOnOCR-2-1B, new capabilities.** LightOnOCR-3-1B keeps the architecture of **LightOn's** previous LightOnOCR-2 models, so switching requires no change, and adds the new grounding, image description and chart extraction features. LightOnOCR-3 is a new family of highly performant lightweight OCR models. Compared to the previous generation, they bring significant improvements in speed and transcription quality and introduce new visual understanding features: the models now output bounding box coordinates with labels for all visual elements of a document, short descriptions of images, and the numerical data of figures and charts. With these capabilities, they offer a ready-to-use, easier-to-maintain alternative to complex document understanding pipelines. The models come in three sizes. The 1B keeps the LightOnOCR-2-1B architecture, while the 0.8B and 4B adopt the Qwen3.5 vision-language architecture, which simplifies integration with existing tools and brings a significant speed-up. All models are released under the Apache 2.0 license for research and commercial use.
