Libraries

How to use veriloop-lab/veriloop-coder-e1 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="veriloop-lab/veriloop-coder-e1")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("veriloop-lab/veriloop-coder-e1")
model = AutoModelForImageTextToText.from_pretrained("veriloop-lab/veriloop-coder-e1")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"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]:]))

# VeriLoop Coder-E1 Rollback Adapter

This folder contains the public-safe PEFT artifacts for `rollback_adapter` in VeriLoop Coder-E1.

## Role

Rollback/revision obedience, validator-aware repair boundaries, worktree-safe correction behavior.

## Included files

- `adapter/adapter_config.json`
- `adapter/adapter_model.safetensors`
- `adapter/README.md`
- Custom VeriLoop head file(s): rollback_head.pt
- `veriloop_adapter_manifest.json`
- `metrics_summary.json`

## Excluded from public release

Training JSONL files, evaluation JSONL files, logs, optimizer states, scheduler states, intermediate checkpoints, repeated tokenizer snapshots, and private absolute-path manifests are intentionally excluded.

## Quality summary

Best quality score: `0.7339887002259493`

This adapter is intended to be used under the VeriLoop Coder-E1 Harness runtime. It should not be treated as a standalone replacement for the full runtime, validator, evidence, rollback, sandbox, and observability stack.
