MagicPrompt TinyStories-33M (LoRA)
Info
Magic prompt completion model trained on a dataset of 80k Stable Diffusion prompts. Base model: TinyStories-33M. Inspired by MagicPrompt-Stable-Diffusion.
Model seems to be pretty decent for 33M params due to the TinyStories base, but it clearly lacks much of an understanding of pretty much anything. Still, considering the size, I think it's decent. Whether you would use this over a small GPT-2 based model is up to you.
Examples
Best generation settings I found: max_new_tokens=40, do_sample=True, temperature=1.2, num_beams=10, no_repeat_ngram_size=2, early_stopping=True, repetition_penalty=1.35, top_k=50, top_p=0.55, eos_token_id=tokenizer.eos_token_id, pad_token_id=0 (there may be better settings).
no_repeat_ngram_size is important for making sure the model doesn't repeat phrases (as it is quite small).

Next steps
- Larger dataset ie neuralworm/stable-diffusion-discord-prompts or daspartho/stable-diffusion-prompts
- More epochs
- Instead of going smaller than GPT-2 137M, fine tune a 1-7B param model
Training config
- Rank 16 LoRA
