Nvidia is in talks to backstop roughly $250B in financing for OpenAI’s 10-GW data-center project, while a new diffusion-based LLM called Celeris-1 claims near-GPT-5 intelligence with 157ms latency. NSW Liberals face ICAC scrutiny over secret tapes and sham payments, SpaceX’s 13th Starship splashdown sets up a tower-catch attempt, and Jodrell Bank Observatory faces closure after losing major funding.
