Gemma4-E4B-SFT-Fable5-Glint

A LoRA fine-tune of `unsloth/gemma-4-E4B-it`, supervised fine-tuned on ermiaazarkhalili/Fable-5-Glint-Clean (private).

Base model`unsloth/gemma-4-E4B-it`
ArchitectureGemma4ForConditionalGeneration
Parameters8.0B
Training dataermiaazarkhalili/Fable-5-Glint-Clean (private)
MethodLoRA supervised fine-tuning via Unsloth + TRL
Licenseapache-2.0 (inherited from the base model)

Usage

python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "ermiaazarkhalili/Gemma4-E4B-SFT-Fable5-Glint"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype='auto', device_map='auto')

messages = [{"role": "user", "content": "Explain gradient checkpointing in two sentences."}]
inputs = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True, return_tensors='pt'
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Held-out evaluation

Next-token accuracy on a deterministic held-out split of ermiaazarkhalili/Fable-5-Glint-Clean (n = 199 samples), scored against the base model `unsloth/gemma-4-E4B-it`. Assistant tokens only; both models are scored identically.

A delta measures how far fine-tuning moved this model from its own starting point; it is not a ranking against other models, which start from different baselines.

Observed training loss

Measured from our SLURM logs for this configuration. These are training-loss observations only — see the held-out evaluation above for measured accuracy.

Limitations

  • —No benchmark evaluation has been run on this checkpoint. The only reported numbers are training-loss observations.
  • —Inherits the biases, knowledge cutoff and failure modes of the base model.
  • —Fine-tuned on a single instruction-following dataset; behaviour outside that distribution is untested.
  • —LoRA adapters were merged into the base weights, so the merged model cannot be detached from this fine-tune.

Reproducing

Trained by notebooks/fable_distillation_gemma4-e4b_fable-glint_unsloth.ipynb, executed non-interactively with papermill on a SLURM H100 partition (Unsloth + TRL, LoRA).
