## Training Details
|
| 68 |
-
|
| 69 |
-
I trained this model from scratch using:
|
| 70 |
-
- Custom BPE tokenizer (trained on the same data)
|
| 71 |
-
- GPT-2 architecture (just way smaller)
|
| 72 |
-
- AdamW optimizer with a learning rate of 0.0005
|
| 73 |
-
- Batch size of 8
|
| 74 |
-
- Trained for 10 epochs
|
| 75 |
-
|
| 76 |
-
The whole thing runs on a regular laptop - no fancy GPU clusters needed!
|
| 77 |
-
|
| 78 |
-
## Limitations
|
| 79 |
-
|
| 80 |
-
Let's be real here:
|
| 81 |
-
- This model is TINY. Like, really tiny. It has 1,065,728 parameters vs GPT-3's 175 billion.
|
| 82 |
-
- It was only trained on 5,000 Wikipedia samples, so its knowledge is... limited.
|
| 83 |
-
- It might generate weird or nonsensical text sometimes. That's part of the charm!
|
| 84 |
-
- Maximum context length is only 128 tokens, so don't expect long conversations.
|
| 85 |
-
- It's a base model with no instruction tuning, so it just continues text rather than following commands.
|
| 86 |
-
|
| 87 |
-
## Why I Made This
|
| 88 |
-
|
| 89 |
-
I wanted to understand how language models work by building one myself. Sure, I could've just fine-tuned a pre-trained model, but where's the fun in that? This project taught me about:
|
| 90 |
-
- Tokenizer training
|
| 91 |
-
- Transformer architecture
|
| 92 |
-
- Training dynamics
|
| 93 |
-
- How LLMs actually generate text
|
| 94 |
-
|
| 95 |
-
Plus, now I can say I trained a language model from scratch on my laptop. Pretty cool, right?
|
| 96 |
-
|
| 97 |
-
## Future Improvements
|
| 98 |
-
|
| 99 |
-
Some things I might try:
|
| 100 |
-
- Train on more data (maybe the full WikiText dataset)
|
| 101 |
-
- Experiment with different model sizes
|
| 102 |
-
- Try different tokenizer configurations
|
| 103 |
-
- Add instruction tuning
|
| 104 |
-
- Fine-tune it for specific tasks
|
| 105 |
-
|
| 106 |
