# Tessera-1B-Nano vs Tessera-1B-Nano-Base
Side-by-side demo for the token-matched comparison described in the
[Tessera-1B-Nano repository](https://github.com/yava-code/Tessera-1B-Nano). Three generations per run:
the NTP-only baseline, the concept arm with predicted feedback, andthe concept arm with its concept feedback zeroed at inference. A readout panel reports the teacher-forced NTP
loss of each model on the prompt and the zero-feedback penalty of the concept arm.
Runs on ZeroGPU: the checkpoints load on CPU at startup and each request moves compute to
a shared A100 through the `spaces.GPU` decorator.
The checkpoints: [Tessera-1B-Nano](https://huggingface.co/yava-code/Tessera-1B-Nano) and
[Tessera-1B-Nano-Base](https://huggingface.co/yava-code/Tessera-1B-Nano-Base). The full
study, including the committed intervention numbers (zeroing costs +0.1050 nats on held-out
data, shuffling costs +0.0008), is in the repository whitepaper.
