# VisualEars FastConformer FA Full AB - QAT W2 Materialized
This repo contains the current 2-bit QAT materialized NeMo checkpoint from the VisualEars FastConformer Persian ASR quantization experiments.
Important: this is a **materialized float NeMo checkpoint**, not a packed 2-bit deployment artifact yet. The selected QAT linear weights are projected to their 2-bit values and saved back into normal NeMo/torch tensors, so the file size is still close to the full precision `.nemo`.

Default decoding:
| model | WER | CER |
|---|---:|---:|
| FP baseline | 32.64% | 13.30% |
| W2 materialized | 37.47% | 16.69% |
Forced CTC:
| model | WER | CER |
|---|---:|---:|
| FP baseline | 34.96% | 14.36% |
| W2 materialized | 40.65% | 17.78% |
This is useful as an experimental checkpoint, but it is not yet parity and not yet compressed/bit-packed.
