            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("josephmayo/gemma-4-E4B-it-Coder")
model = AutoModelForImageTextToText.from_pretrained("josephmayo/gemma-4-E4B-it-Coder")

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Gemma 4 E4B IT Coder

This is the full merged coding-tuned model from google/gemma-4-E4B-it plus the LoRA adapter josephmayo/gemma-4-E4B-it-coding-lora. The release is not adapter-only: the LoRA deltas were merged directly into the base safetensors and uploaded as a normal Transformers model.

Training Proof

Training ran on Kaggle with 2x Tesla T4 GPUs.

Item	Value
Safe coding rows	1024
LoRA steps	200
LoRA rank	16
LoRA alpha	32
Trainable parameters	50,499,584
Final train loss	1.1427
Merged LoRA tensors applied	592/592
Missing LoRA targets	0
Merged safetensor shards	5

HumanEval Results (50-Problem Subset)

Evaluated on Kaggle with 2x Tesla T4 GPUs using an executable 50-task HumanEval subset. Full generated before/after code is published in eval50_before_after_full_code.csv.

Metric	Base `google/gemma-4-E4B-it`	Coder
Pass count	34 / 50	42 / 50
Absolute lift	-	+16.0 pp
Relative pass-count lift	-	+23.53%

Proof files included in this repo:

eval50_summary.json: 50-problem HumanEval executable result.
eval50_before_after_full_code.csv: full generated before/after code for all 50 tasks.
EVAL50_README.md: evaluation methodology and scope.
nvidia_smi.txt: GPU environment proof.
eval_before_after.csv: fixed before/after coding prompt scores with output previews.
trainer_log_history.json: training loss and runtime logs.
merge_manifest.json: direct merge record, including 592 applied LoRA tensors and 0 missing targets.
model.safetensors.index.json: shard index for the full merged model.

This model is for benign coding assistance only. The training filter removed malware, phishing, exploit, credential theft, evasion, and destructive automation examples.
