Trained with compute from [Backyard.ai](https://backyard.ai/) | Thanks to them and @dynafire for helping me out. |

Training Details: |
|
<br>Trained at 8K Context -> Expanded to 32K Context with PoSE training. |
|
|
|
Dataset Modifications: |
|
<br>\- Further Cleaned up Roleplaying Samples -> Quality Check |
|
<br>\- Removed Low Quality Samples from Manual Check -> Increased Baseline Quality Floor |
|
<br>\- More Creative Writing Samples -> 2x Samples |
|
<br>\- Remade and Refined Detailed Instruct Data |
|
|
|
Notes: |
|
<br>\- Training run is much less aggressive than previous Stheno versions. |
|
<br>\- This model works when tested in bf16 with the same configs as within the file. |
|
<br>\- I do not know the effects quantisation has on it. |
|
<br>\- Roleplays pretty well. Feels nice in my opinion. |
|
<br>\- It has some issues on long context understanding and reasoning. Much better vs rope scaling normally though, so that is a plus. |
|
<br>\- Reminder, this isn't a native 32K model. It has it's issues, but it's coherent and working well. |

Relevant Axolotl Configurations: |
|
<br>-> Taken from [winglian/Llama-3-8b-64k-PoSE](https://huggingface.co/winglian/Llama-3-8b-64k-PoSE) |
|
<br>\- I tried to find my own configs, hours of tinkering but the one he used worked best, so I stuck to it. |
|
<br>\- 2M Rope Theta had the best loss results during training compared to other values. |
|
<br>\- Leaving it at 500K rope wasn't that much worse, but 4M and 8M Theta made the grad_norm values worsen even if loss drops fast. |
|
<br>\- Mixing in Pretraining Data was a PITA. Made it a lot worse with formatting. -> Tried at low value mixes, eg. <20% and lower. |
|
<br>\- Improper / Bad Rope Theta shows in Grad_Norm exploding to thousands. It'll drop to low values alright, but it's a scary fast drop even with gradient clipping. |
