360VL is developed based on the LLama3 language model and is also the industry's first open source large multi-modal model based on
LLama3-70B[
🤗Meta-Llama-3-70B-Instruct]. In addition to applying the Llama3 language model, the 360VL model also designs a globally aware multi-branch projector architecture, which enables the model to have more sufficient image understanding capabilities.
360VL has released the following versions.
-
Multi-round text-image conversations: 360VL can take both text and images as inputs and produce text outputs. Currently, it supports multi-round visual question answering with one image.
-
Bilingual text support: 360VL supports conversations in both English and Chinese, including text recognition in images.
-
Strong image comprehension: 360VL is adept at analyzing visuals, making it an efficient tool for tasks like extracting, organizing, and summarizing information from images.
-
Fine-grained image resolution: 360VL supports image understanding at a higher resolution of 672×672.
