# Qwen2.5-14B Sugarquill v1

A continued pretrain of SuperNova-Medius on assorted short story data from the web. Supernova already had a nice prose, but diversifying it a bit definitely doesn't hurt.
Also, finally a storywriter model with enough context for something more than a short story, that's also nice.

It's a fair bit more temperamental than Gemma, but can be tamed with some sampling.
Instruction following also stayed rather strong, so it works for both RP and storywriting, both in chat mode via back-and-forth co-writing and on raw completion.

Overall, I'd say it successfully transfers the essence of what I liked about Gemma Sugarquill. I will also make a Qwen version of Aletheia, but with a brand new LoRA, based on a brand new RP dataset that's in the making right now.


Model was trained by Auri.

**Training notes**

This model was trained for 2 epochs on 10k rows (~18.7M tokens), taken equally from Erebus-87k and r_shortstories_24k datasets. I've also normalized punctuation to ASCII on the train split, so mismatched quote marks should not be an issue anymore. Also normalized whitespaces, so double spaces after period should be gone as well.

It was trained on 5x3090Ti workstation for 7.5 hours with rsLoRA. I switched back to Axolotl for this run, as LF just plain refused to run at all on this workstation. Also, it's a bf16 LoRA this time. Overall training went much smoother than last time. I've attempted to train Qwen Sugarquill several times before, but loss jumped like crazy. Effective batch size of 40, rsLoRA and paged_ademamix_8bit optimizer seemingly completely solved this issue. 

Thanks to Kearm for providing compute for this training run!

**Format**

Model responds to ChatML instruct formatting, exactly like it's base model.

```
<|im_start|>user
{user message}<|im_end|>
<|im_start|>assistant
{response}<|im_end|>
```

**Recommended Samplers**

I found this configuration to be quite stable:

```
Temperature - 0.8
Min-P - 0.05
Top-A - 0.3
Repetition Penalty - 1.03
```

Feel free to toy around with samplers after you get a feel for it. It seems to like Top-A and Smooth Sampling quite a bit.
