### TINY Frankenstein of [SmolLM-135M](https://huggingface.co/HuggingFaceTB/SmolLM-135M) upped to 0.18b
Use this frankenbase for training. 
Sorry for the mislabelling, the model is a 0.18b 181m parameter, not 0.15. 
I did not except this repo to blow up and now all the training scripts depend on it.

* ## CITE WORK FROM THIS HF PAGE AND [@cognitivecompai](https://huggingface.co/ehartford)'s  OPTIMIZER ON YOUR FUTURE PAPERS OR I WILL DRAG YOUR ORG ON TWITTER LIKE I DID WITH COHERE LOL (we're cool now btw, visited them :)

>>[!TIP]🐧 If you're impppatient, get the trained checkpoint file that runs on 1 cpu core:
>>
>>wget https://huggingface.co/nisten/Biggie-SmoLlm-0.15B-Base/resolve/main/biggie_groked_int8_q8_0.gguf
>>
>>make sure to install latest llama.cpp first, it's easy on linux & mac:
>>
>> git clone https://github.com/ggerganov/llama.cpp && cd llama.cpp && make -j

Now for the magic trained finetune that runs at insane speeds:

The settings are very finicky so be careful with your experimentation
```verilog
./llama-cli -fa -b 512 -ctv q8_0 -ctk q8_0 --min-p 0.3 --top-p 0.85 --keep -1 \
  -p "You are a NASA JPL Scientists. Human: I want to bring my cat to mars." \
  --in-prefix "<|im_start|>Human:" --reverse-prompt "Human:" \
  -m biggie_groked_int8_q8_0.gguf -co -cnv \
  -c 1024 -n 700 --temp 1.5 -ngl 0 -t 1
```
Yup, that's no gpu, 1 cpu core. 

This base model was built one via semi-automated continuous merging to figure out the recipe.
Model is more coherent. 

The temperature settings and min p etc need to be adjusted but even at default temp0 it was coherent for first 100 tokens. 
Amazing option for further training. And this is a merge of the base, not the instruct!

## 🧠 What's Really Going Down Here?

We're talking about a convergence of whole bunch of stuff, more papers will be written about this:

1. **Evolutionary Merging**: 
2. **BitNet Integration**: 
4. **Experimental GrokAdamW Optimizer**:

## Prior work, from last week

Credits for optimizer go to [@cognitivecompai](https://github.com/cognitivecomputations/grokadamw) for laying the groundwork with the original GrokAdamW optimizer.

## LETS TRY OUT THE EXPERIMENTAL GROKKED FINETUNE:

```bash
wget https://huggingface.co/nisten/Biggie-SmoLlm-0.15B-Base/resolve/main/biggie_groked_int8_q8_0.gguf 
```

Yes we will be talking with a 164mb file that runs at 160 tokens per second on a single cpu core
## you read all of that correctly yes, 1 cpu core 160 tps https://x.com/nisten/status/1819752034305970649
![image/png](https://cdn-uploads.huggingface.co/production/uploads/6379683a81c1783a4a2ddba8/nTNISjByBkN7bJZzuOvOw.png)

## 🚀 run it with NO GPU and only one CPU core it with these settings 
```bash
./llama-cli -n -1 -fa -b 512 -ctv q8_0 -ctk q8_0 -fa --min-p 0.3 --top-p 0.85 --keep -1 -p "You are a NASA JPL Scientists. Human: I want to bring my cat to mars." -m biggie_groked_int8_q8_0.gguf -co -cnv --in-prefix "<|im_start|>Human:" --reverse-prompt "Human:" -c 1024 -n 512 --temp 1.5 -ngl 0
```


## 🏋️ Training Tutorial, MAKE YOUR OWN BIGGIE_SMOlLM


Clone the repo like you're stealing code from the future:
```bash
git clone https://github.com/nisten/grokadamw
cd grokadamw
```

Fire up the training script and watch the magic happen:
```bash
python smoltrainer.py
```

## 💻 Do it from scratch yourself
Install the secret sauce (dependencies):
```bash
pip install torch transformers datasets tqdm

make a file named meow.py , copy paste in this code, and then run it ```python meow.py```
