    🧵 Time for a short end-of-2025 wrap up 🧵 Genuinely aiming for this to be a short one for two reasons: 1. I'm doing it at the last moment 😅 2. Most of what I was involved in is not stuff that can be shared publicly (yet… or ever?). Or maybe I was just lazy... Let's go [1/12]

    Disappointed to hear the @TfL announcement system in King's Cross blast an @audible_com announcement formatted as a normal announcement. Misleading, tasteless, and unwelcome.

    It's recursive self-improvement if it works, reward hacking if it doesn't.

    I'm so happy to be able to announce the first general purpose sign-language-to-text translation (SL2T) model from my team that's out today and powering a new ASL input feature on @Android phones (and don't worry, we're not stopping at ASL).
