Dr. Alan Becker, a deep learning scientist who previously led the development of Snapchat's 'My AI' chatbot, has recently come back to launch a new company called eSelf. This startup is focused on creating a real-time, video-based conversational AI assistant platform and has successfully secured $4.5 million in seed funding, officially entering the fierce competition in the field of AI assistants. eSelf's early goal is to provide a more realistic and interactive AI experience for verticals such as education, sales, financial services, real estate, and healthcare.

Generating high-quality, temporally continuous videos requires a significant amount of computational resources, especially for longer time spans. The latest Diffusion Transformer model (DiTs) has made significant progress in video generation, but its reliance on larger models and more complex attention mechanisms has resulted in slower inference speeds, exacerbating the challenge. To address this issue, researchers at Meta AI have proposed a training-free method called AdaCache to accelerate video DiTs.

Recently, OpenAI launched an important update that introduces the 'Predicted Outputs' feature for the GPT-4o model. This innovative technology significantly enhances the model's response speed, achieving up to 5 times the original speed in specific scenarios, providing developers with a completely new efficiency experience. This feature, developed in collaboration with FactoryAI, has a core advantage of bypassing the process of repeated generation of known content. In practical applications, especially in updating blog posts and iterating on existing content.

Large Language Models (LLMs) like GPT and Llama have sparked a revolution in the field of artificial intelligence, but efficiently training these massive models while aligning them with human values remains a challenge. Reinforcement Learning with Human Feedback (RLHF) has become an important training method for LLMs in recent years, but traditional RLHF frameworks have limitations in flexibility, efficiency, and scalability. To address these issues, the ByteDance Doubao Large Model Team has open-sourced an RLHF framework called HybridFlow.
