ZTC probe for Darwin-180B-RSI is now in the repo (early release)

The Zero-Token Confidence (ZTC) probe for Darwin-180B-RSI is now available in the model repository.

ZTC estimates how likely the model is to answer a question correctly, before it generates a single token. It reads the final-layer hidden state at the last prompt token and maps it to a probability with a small calibrated linear probe. It costs one forward pass over the prompt, with no extra generation and no second model.

What's in the repo:

  • ztc/ztc_probe_darwin180rsi.npz: the probe weights
  • handler.py: returns the answer and its confidence together as JSON
  • ztc/usage.py: a minimal example
  • ztc/README.md: how it works and its limits

This is an early probe. It reaches an AUROC of 0.64 on our held-out validation split, which makes it a coarse signal. It's useful for routing, such as deciding where to spend extra samples or which cases to send for review, but not as a correctness guarantee. A retrained version with more data will replace it, and we'll post the new numbers when it ships.
