| # probe-inference parity fixture |
|
|
| Test fixture for the `probe-inference` package's parity tests (`tests/test_parity.py`). The tests |
| download this dataset at a pinned revision and check that the package reproduces reference scores on |
| real activations. |
|
|
| For each model it holds a few rows of residual-stream activations and token masks, and the reference |
| score of each probe on each row. It holds no probes: the tests load them from |
| [`AlignmentResearch/probe-inference-weights`](https://huggingface.co/AlignmentResearch/probe-inference-weights) |
| at the package's pinned revision, exactly as users do. |
|
|
| | Directory | Model | Rows | Probes | |
| |---|---|---|---| |
| | `nemotron-3-super-120b/` | `nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16` | 80 | EFC, axial | |
| | `qwen3.5-9b/` | `Qwen/Qwen3.5-9B` | 32 | linear, MLP, EFC, axial | |
|
|
| Files in each model directory: |
|
|
| - `acts.pt`: `{layer: Tensor[rows, seq, d_model]}` in bfloat16, the outputs of decoder block `layer` |
| (Hugging Face `hidden_states[layer + 1]`), over each row's follow-up window. |
| - `masks.pt`: `tokens`, `prompt_mask`, `completion_mask` and `followup_start_positions` for the same rows. |
| - `reference.json`: per probe, `score` (EFC, axial), or `L<layer>` logits plus `combined` (the mean of |
| per-layer sigmoids) for linear and MLP, one value per row. |
|
|
| `manifest.json` lists the sets and, for each, the probes' paths in the weights repository (for example |
| `qwen3.5-9b/efc`). The Nemotron rows mix two follow-up lengths, so a batch has ragged read windows (27 |
| and 24 tokens). |
