OpenVINO/Phi-3-mini-4k-instruct-int4-ov warn
Weights only ship in a format that can run code when loaded; loading it runs custom code from the repo. Plus 1 minor note.

Findings
Scanned 2026-08-21 · published from a community scan.
medium Pickle-serialized weights, no safetensors
Weights ship only as pickle-based files (openvino_detokenizer.bin, openvino_model.bin, openvino_tokenizer.bin). Loading pickle executes arbitrary code from the file — prefer a safetensors release or load in a sandbox.
How to fix
Convert the weights to safetensors before loading them anywhere that matters.
- Do not load the pickle files in-process — pickle deserialization executes arbitrary code from the file.
- Convert locally in a sandbox: `pip install safetensors` and use `safetensors.torch.save_file` on a state dict loaded with `torch.load(..., weights_only=True)` (refuses most code-execution payloads), or use Hugging Face's `convert.py` space/script.
- Pin the exact revision hash you converted from, and load only your converted safetensors artifact from then on.
medium Repo ships executable Python (trust_remote_code)
The repository contains custom code files that run in-process when loaded with trust_remote_code=True. Pin the revision hash and review the code before loading.
How to fix
Review and pin the custom code; never float on `main` with trust_remote_code=True.
- Read every `.py` file in the repo before first load — this code runs in your process.
- Pin the revision: `from_pretrained(model_id, revision="<commit sha>", trust_remote_code=True)` so a later push can't swap the code under you.
- Prefer a version of the architecture already in `transformers` if one exists, which removes the remote-code requirement entirely.
info Pickle static analysis clean
Opcode-level parse of openvino_detokenizer.bin, openvino_model.bin, openvino_tokenizer.bin (no code executed) found only standard serialization globals (0 distinct, all torch/collections/numpy). Pickle remains an executable format — this verifies the current bytes, not future uploads; prefer a safetensors release.
low Pickle checkpoint only partially analyzable
Static analysis could not fully parse: openvino_detokenizer.bin: legacy parse stopped after 0 pickle(s): unsupported pickle opcode 0xb at 0, openvino_model.bin: legacy parse stopped after 0 pickle(s): unsupported pickle opcode 0x0 at 0, openvino_tokenizer.bin: legacy parse stopped after 0 pickle(s): unsupported pickle opcode 0x0 at 0. Unparsed content is unverified.
Remediation guidance addresses the documented findings only. It is evidence-driven repair, not a safety certification of the model.
