Llama-3-13B-Instruct-ft
This is a QLoRA finetune of a merge of pre-trained language models created using mergekit.
The model is based on my passthrough merge of Llama-3-13B-Instruct
This was primarily an experiment to see how a passthrough merge will respond to further finetuning, though this was done on a small dataset.
The goal was to make a "mid" sized model like Meta has released in the past and the merge method was inspired by mlabonne's Llama-3-120B.
The model was finetuned on 8192 context length and is likely reliable using RoPE up to 32k.
It still cannot do math reliably; neither can Llama-3-8B, and in my tests only Llama-3-70B passes basic arithmetic, but it is a better storywriter/RP than Llama-3-8B from some side by side testing I conducted.
Further finetuning this model or finetuning the base model on more samples is encouraged.
Datasets
A small dataset was used to see how it affects performance. Originally I planned to do a larger dataset (196k samples), but wanted to start with a smaller one first to see how much the model improved with some additional finetuning.
Next steps would be finetuning on a larger dataset if through further testing, performance improvements are noticed.
Finetuning details
This is a QLoRA model and all modules were targeted.
lora_target_modules:
- gate_proj
- down_proj
- up_proj
- q_proj
- v_proj
- k_proj
- o_proj
lora_modules_to_save:
- embed_tokens
- lm_head
The following hyperparameters were used during training:
- learning_rate: 1e-05
- train_batch_size: 1
- eval_batch_size: 1
- seed: 42
- distributed_type: multi-GPU
- num_devices: 3
- total_train_batch_size: 3
- total_eval_batch_size: 3
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: cosine
- lr_scheduler_warmup_steps: 25
- num_epochs: 1
Optimizer paged_adamw_8bit and Deepspeed ZeRO 3 was used at a LR of 1e-5 using the cosine scheduler for 1 epoch on 3x3090s taking 4h 12m 13s total.
Sample packing and padding was disabled to reduce VRAM consumption significantly at the cost of speed.
