0ARCH Core

Our AI starts with a model we trained from nothing.

Core is the AI line at 0ARCH. This is the real training record of Kisoku, the language model we built from scratch, step by step.

  1. Stage 1: learning language

    199,000 steps of general text. The loss falls fast, then slowly, as the model works out how language fits together. The preview you can download today was cut at the end of this stage.

  2. Stage 2: math and code

    25,000 steps with much more math and code in the mix, aimed at the preview's weakest spots. Part of the sudden drop is the new data being easier to predict.

  3. Stage 3: cool-down

    The last 19,000 steps. The learning rate winds down and reasoning examples come in, so what it learned settles. The October release is built on the end of this line.

Training loss, lower is better. Each point averages 1,000 training steps, about 1.5 billion words, from our run log. The log starts at step 28,650; earlier steps weren't kept.

Kisoku

A small, free language model that runs offline on your own laptop, so nothing you type leaves your computer. Good at everyday questions, short writing and simple code. Still a preview, so it gets math wrong and can sound sure when it isn't.
