Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "ermiaazarkhalili/Carnice-9B-SFT-Fable5"
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-Complete-2M-Clean (n = 19,994 samples), scored against the base model kai-os/Carnice-9b. Assistant tokens only; both models are scored identically.
| Metric | Base | This model | Δ |
|---|---|---|---|
| Top-1 accuracy | 0.7317 | 0.7745 | +0.0428 |
| Top-5 accuracy | 0.9188 | 0.9436 | +0.0247 |
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.
| SLURM job | Steps | First loss | Final loss |

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_carnice-9b_fable_unsloth.ipynb, executed non-interactively with
papermill on a SLURM H100 partition (Unsloth + TRL, LoRA).
