Llama 2 13b is a pretty decent language model. You know what's probably better? *Two* Llama 2 13b models. In a trenchcoat. |
|
|
|
Produced by [`bakllama.py`](https://github.com/cg123/mergekit/blob/main/bakllama.py) with this config file: |
|
```yml |
|
layer_slices: |
|
- model: TheBloke/Llama-2-13B-fp16 |
|
start: 0 |
|
end: 40 |
|
- model: TheBloke/Llama-2-13B-fp16 |
|
start: 0 |
|
end: 40 |
|
``` |
|
|
|
No fine tuning was done on this model. Yes, it's still coherent somehow. |

Benchmark results: |
|
| Benchmark | Llama2-13b | Llama2-26b-tcs | Percent Change | |
|
| --- | --- | --- | --- | |
|
| ARC | 59.3 | 55.03 | -7.2% | |
|
| HellaSwag | 82.15 | 79.9 | -2.74% | |
|
| MMLU | 55.67 | 53.73| -3.48% | |
|
| TruthfulQA | 37.39 | 40.48 | +5.59% | |
|
| Average | 58.63 | 57.29 | -2.29% | |
|
| Average Minus TQA | 65.70 | 62.85 | -4.34% | |
|

|
This tells us two very important things: |
|
1. TruthfulQA is a perfect benchmark in every way. |
|
2. Llama models are amazingly robust to being fed their own output. |
