+# LLaVAction-7B
+
+## Model Summary
+The LLaVAction models are 7B parameter models trained on LLaVA-Video-178K and EPIC-KITCHENS-100-MQA, based on Qwen2 language model with a context window of 32K tokens.
+
+This model supports at most 64 frames.

+## Use
+
+### Intended use
+The model was trained on EPIC-KITCHENS-100-MQA and LLaVA-Video-178K (link). It has improved capability on understanding human egocentric actions from videos.

+
+### Generation
+We provide the simple generation process for using our model. For more details, you could refer to Github.
