Llama-3-13B-Instruct-ft

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

• Chat-Error/Pure-dove-sharegpt

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.
