class JanusForMultiModal extends AnnotatorModel[JanusForMultiModal] with HasBatchedAnnotateImage[JanusForMultiModal] with HasImageFeatureProperties with WriteOpenvinoModel with HasGeneratorProperties with HasEngine

JanusForMultiModal can load Janus models for unified multimodal understanding and generation. The model consists of a vision encoder, a text encoder, and a text decoder. Janus decouples visual encoding for enhanced flexibility, leveraging a unified transformer architecture for both understanding and generation tasks.

Janus uses SigLIP-L as the vision encoder, supporting 384 x 384 image inputs. For image generation, it utilizes a tokenizer with a downsample rate of 16. The framework is based on DeepSeek-LLM-1.3b-base, trained on approximately 500B text tokens.

Pretrained models can be loaded with pretrained from the companion object: {{ val visualQA = JanusForMultiModal.pretrained() .setInputCols("image_assembler") .setOutputCol("answer") }} The default model is "janus_1_3b_int4" if no name is provided.

For available pretrained models, please refer to the Models Hub.

Models from the HuggingFace 🤗 Transformers library are also compatible with Spark NLP 🚀. For compatibility details and import instructions, see https://github.com/JohnSnowLabs/spark-nlp/discussions/5669. For extended examples, refer to https://github.com/JohnSnowLabs/spark-nlp/blob/master/src/test/scala/com/johnsnowlabs/nlp/annotators/cv/JanusForMultiModalTest.scala.

Example

{{ import spark.implicits._
