# SELI Auditor BF16

SELI Solidity audit artifact.

## Variant

**Merged BF16 Hugging Face model.** This variant contains the seed adapter plus the local SELI fine-tune merged into the Qwen2.5-Coder base.

Training stack:

```text
Qwen/Qwen2.5-Coder-7B-Instruct
  -> merge seed adapter: jhsu12/solidity-vulnerability-detector
  -> train local SELI LoRA on audit dataset
  -> merge local SELI LoRA
  -> artifact: BF16 safetensors model
```

Use this variant for highest quality Transformers/vLLM/SGLang serving when VRAM allows.

## Minimal Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "0xtoshi/seli_auditor-BF16"
tok = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="bfloat16",
    device_map="auto",
    trust_remote_code=True,
)
```


## Intended Use

Authorized smart-contract security review, local regression testing, PoC planning in owned/authorized scopes, audit triage, and invariant-focused code review. The dataset is intentionally proof-gated around finding classes such as shared-pool reentrancy, callback ordering, money-flow drift, AST/IR mapping, decompiler parity, transfer parity, stale accounting, bridge replay, oracle manipulation, access-control bypass, proxy/storage collision, and Foundry proof construction.
