The model is CogAgent-chat-18B finetuned (LoRA with rank 8 added to the language decoder) on 160K WebSight examples.

The model is in the format of SAT (SwissArmyTransformer).

Please refer to our paper and our codebase to run inference.

Use of the model must comply with the original model license and the original data license (CC-BY-4.0).
