    Fully client-side GPT2 prediction visualizer▲153

    Hi HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…

    Hello HN, I made this simple notepad for writing down whatever comes to mind. The goal is to force you to not get hung up on what you’ve already written. There’s no formatting, you can’t edit what you’ve typed, you can’t select text or move your caret around. There’s no backspace, delete, undo/redo, or paste. You can’t even see any words except the one you’re currently typing, and when you’re done with it, it fades away. The text is all still there, just invisible. You can save everything you’ve written as a .txt if you want, or just empty your thoughts and let them disappear forever.…
