# Qwen2.5-14B Neon v1

RP finetune of Supernova-Medius. Turned out surprisingly nice on it's own, I honestly made it only as a merge fuel, but it impressed me and Prodeus enough to release it separately (history repeats I guess, Sugarquill also started out this way). Quite interesting prose, definitely quite distinct from Supernova or EVA for that matter.
Instruction following is decent as well. Not really much to say about this one, just a decent RP model, tbh. Euryale-inspired I guess.

Model was trained by Auri.

**Training notes**

Model was trained on a dataset consisting of 77M tokens of synthetic RP and short story gen data. Training took around 2 hours on 8xH100 SXM node. Training config was more or less reused from Sugarquill, and it worked fairly well again.
Had the node crash after finishing the training and merging in the LoRA, so I had to merge it with MergeKit on a separate node, otherwise everything was smooth.

Huge thanks to Retis Labs for sponsoring this run!

**Format**

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

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

**Recommended Samplers**

My classic stable Qwen setup works quite well:

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