+# ViT for Multitask
+
+## Overview
+
+A small **ViT** implementation for **Multitask**, packaged with an explicit configuration and an initialization checkpoint. The **small** variant is a reproducible starting point, not a trained model release.
+
+## Repository status
+
+- The Python file contains the model and runnable example or training entry point.
+- `config.json` records the generated architecture settings.
+- `training_args.json` records the default experiment recipe.
+- `model.safetensors` is a valid initialization checkpoint for smoke tests; it is **not** presented as a trained benchmark checkpoint.
+- No benchmark score is claimed in this repository.
+
+## Architecture
+
+| Item | Value |
+|---|---|
+| Architecture | ViT |
+| Scale | small |
+| Attention | sliding window |
+| Fusion | tensor fusion |
+| Activation | swish |
+| Normalization | groupnorm |
+
+## Default experiment recipe
+
+The included configuration uses **rmsprop** with a **linear warmup** schedule. These are starting values in the script, not evidence of a completed run. For a meaningful evaluation, train all baselines with the same data exposure, tuning budget, and random seeds.
+
+## Quick check
+
+```bash
+python main.py --help
+```
+
+Inspect the script's `__main__` block for its generated smoke-test example. Because this is a custom implementation, generic automatic loading APIs require an explicit adapter before use.
+
+## Evaluation guidance
+
+A useful first evaluation would use **a task-specific held-out set**, report the task metric across at least three seeds, and include a matched-capacity baseline. Keep training logs and environment versions with any published result.
+
+## Limitations
+
+The initialization checkpoint has not been trained or audited for robustness, fairness, or domain transfer. The implementation should be treated as an experimental starting point. Results from a future trained checkpoint must be documented separately from the defaults shipped here.
