OpenAI launches GPT-4o and other multimodal AI models

OpenAI recently launched a multimodal AI model called GPT-4o, which combines multiple modal data such as vision, language and sound to achieve cross-modal learning. In addition, models such as Google's Project Astra, Musk's Gork-3, Zhipu AI's AutoGLM and DeepSeek's Janus-Pro have also made important progress in the field of multimodal AI.
