BYTEDANCE'S NEW AI VIDEO MODEL CAN MAKE 30-SECOND CLIPS FROM A SINGLE PROMPT

ByteDance's new Seedance 2.5 AI video generation model can generate 30-second, 4K videos with a single prompt. Users are able to provide up to 50 images, videos, or audio clips as reference pieces. Increasing the number of references gives users more control over the video creation process. The model will be available in China next month. ByteDance has not announced a release time window for other countries.

PROMPT INJECTION AS ROLE CONFUSION

Modern large language models use role tags as both a security architecture and cognitive scaffolding. Prompt injections are driven by a flaw in how AI models perceive roles. For LLMs, everything arrives through the same channel as one long token soup, so they can't distinguish between their own thoughts and speech. Unless AI models achieve genuine role perception, injection defense will remain a perpetual whack-a-mole game.

OPENAI PREPARES BIDIRECTIONAL VOICE MODE FOR ROLLOUT ON CHATGPT

OpenAI has started rolling out Bidirectional Voice Mode for ChatGPT. The company's new audio generation model, Bidi 1, lets the assistant speak, hear, and listen at the same time. It is able to hold the thread of a whole conversation and switch tasks on the fly if interrupted. The model can sing and beatbox, but there are some tight copyright restrictions. OpenAI has yet to make a formal announcement about the model, but some users are already seeing it in their model selectors.
