Video AI startup RunwayML has introduced a new "Expand Video" feature. It allows users to change video aspect ratios by generating additional content around the original footage using text prompts. The system aims to maintain visual consistency while adding new areas to the frame. The company says users can create camera movements like crash zooms and pull-back shots by combining multiple video expansions. This allows static footage to be transformed into sequences with cinematic camera motion. RunwayML plans to roll out Expand Video gradually for Gen-3 Alpha Turbo users. The company's Runway Academy provides tutorials on using the new feature.

OpenAI is reportedly considering developing a web browser that would work with its chatbot technology. According to a report from The Information, the AI company has started discussions with various partners to integrate search functions for travel, food, real estate, and retail websites. In addition, Darin Fisher, co-developer of the Chrome browser, joined OpenAI in November. Sources say the whole project is still in its early stages with no clear launch timeline. OpenAI has already made steps toward competing with Google through its ChatGPT desktop app and ChatGPT search. A dedicated browser would mark a significant expansion of these efforts. Google currently maintains its grip on the search market in part through its Chrome browser, although this advantage could be weakened if U.S. regulators are successful in their efforts to force Google to sell Chrome.

DeepSeek has launched its new AI model "DeepSeek-R1-Lite-Preview" on chat.deepseek.com. The language model specializes in mathematical thinking and logical reasoning. According to DeepSeek, the model shows strong performance on AIME and MATH benchmarks, which test mathematical abilities, matching the level of OpenAI's o1-preview. This performance is by design: Like OpenAI's model, DeepSeek-R1 is a "reasoning model," meaning the quality of its answers improves with longer thinking processes. One key difference is transparency - users can watch the system's thinking process in real time, while OpenAI only shows a summary. The company has previously released high-performing open-source models and plans to make both an API and R1 available as open source. DeepSeek hasn't announced a specific date for the open-source release.
