# Blip for Multitask

## Overview

A small **Blip** implementation for **Multitask**, packaged with an explicit configuration and an initialization checkpoint. The **giant** 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 | Blip |
| Scale | giant |
| Attention | sliding window |
| Fusion | concat mlp |
| Activation | approx gelu |
| Normalization | layernorm |

## Default experiment recipe

The included configuration uses **adafactor** with a **exponential** 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 train.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.
