# TinyWay-1.1.0
|
| 2 |
+
|
| 3 |
+
**TinyWay-1.1.0** is a lightweight **decoder-only Transformer language model** trained **from scratch** on limited compute.
|
| 4 |
+
The project demonstrates that meaningful language modeling behavior can emerge from modest-scale models trained in constrained environments such as Kaggle.
|
| 5 |
+
|
| 6 |
+
> **Core idea:** *Understanding LLM training mechanics end-to-end by building, training, debugging, and deploying a Transformer LM without relying on pretrained weights.*

## Training
|
| 26 |
+
|
| 27 |
+
### Dataset
|
| 28 |
+
|
| 29 |
+

| 33 |
+
|
| 34 |
+
* GPT-2 BPE tokenizer
|
| 35 |
+
* Vocabulary size: 50,257
|
| 36 |
+
|
| 37 |
+
### Training Setup
|
| 38 |
+
|
| 39 |
+
* Optimizer: AdamW
|
| 40 |
+
* Learning rate: tuned for stable convergence
|
| 41 |
+
* Gradient accumulation: enabled
|
| 42 |
+
* Gradient clipping: enabled
|
| 43 |
+
* Mixed precision training (AMP)
|
| 44 |
+
* Training performed entirely on **Kaggle GPU environment (12-hour sessions)**
|
| 45 |
+
|
| 46 |
+
### Checkpoints
|
| 47 |
+
|
| 48 |
+
Models were saved at multiple training steps (5k → 30k).
|
| 49 |
+
**TinyWay-1.1.0** corresponds to the **~30k step checkpoint**, which showed the best balance of fluency and stability.

+
|
| 64 |
+
out = mdl.generate(
