OpenAI has added a character field to the ChatGPT interface, allowing users to specify the chatbot's characteristics, communication style, and rules it should follow. The update is currently being rolled out on chatgpt.com and the Windows desktop version, with plans to expand to mobile apps, MacOS, and EU countries in the coming weeks. Existing user-defined instructions will not be affected by this change. The new feature is part of OpenAI's ongoing efforts to personalize ChatGPT, alongside recently added Tasks and Memory capabilities, bringing AI systems closer to becoming personal assistants.
Luma has released Ray2, its latest AI model for video generation. The new model has been scaled to 10 times the compute power of its predecessor and uses a new multimodal architecture. Luma says it's better at natural-looking movement and fine details, while maintaining consistency throughout each scene. Text-to-video generation is available to subscribers through Luma's Dream Machine platform, with image-to-video, video-to-video, and editing tools in upcoming releases. The company also plans to make Ray2 accessible through its API soon.
