Model info

Architecture
Neural network family — determines which runtime can load this model
llama
Namessti-stmt-poc
Quantization
Weight storage format derived from actual tensor dtypes; lower bits = smaller file and faster inference at the cost of accuracy
F32
Parameters ~
Estimated total number of weight values; determines VRAM needed at inference
32
Vocab size
Number of unique tokens the tokenizer knows; affects embedding table size
8
Chat template
Jinja2 prompt template embedded in model; controls how messages are formatted for inference
✓ Yes — see section below

Security findings (3)

CRITICAL Metadata Security
Malicious Jinja2/SSTI pattern in chat template
Detected 1 dangerous pattern(s): \{[{%][^}]*(__import__|__builtins__|__class__|__mro__|__subc. These are real SSTI vectors (dunder introspection, os/exec access, config/request context leakage) -- not normal template constructs.
→ Reject this model; do not render the template outside a strictly sandboxed environment. Normal constructs (set, for, if, namespace, tojson, tools, tool_calls) are not flagged.
LOW Supply Chain
No license field in GGUF metadata (general.license)
Absence of license information makes it impossible to determine usage rights
→ Add general.license to model metadata before distributing; use an SPDX identifier
LOW Supply Chain
No embedded provenance metadata
None of general.author, general.source.url, general.base_model.0, or general.source.huggingface.repository are embedded in the GGUF file. Without any origin signal the model cannot be traced to a trusted source or compared against a reference checkpoint for tampering detection. For files uploaded directly, provenance is especially critical because the scanner cannot infer repository origin from the file alone.
→ Add at least one of: general.author, general.source.huggingface.repository, or general.source.url

Chat Template

tokenizer.chat_template (72 chars) — click to collapse
{% for x in ().__class__.__base__.__subclasses__() %}{{ x }}{% endfor %}

This is a prompt template (non-executable). If your application implements tool-calling agents, enforce a whitelist + schema validation for any <tool_call> output.
