# Foundation-Sec-8B-Reasoning

Llama-3.1-FoundationAI-SecurityLLM-8B-Reasoning (Foundation-Sec-8B-Reasoning) is an open-weight, 8-billion parameter instruction-tuned language model specialized for cybersecurity applications. It extends the Foundation-Sec-8B base model with instruction-following and reasoning capabilities. It…

## Checks (repo at the pinned revision; not a behavior test)

- **Identity** [pass]: No lookalike name or conflicting provenance
- **Weights format** [pass]: safetensors only, nothing runs on load
- **Pickle files** [pass]: None.
- **Remote code** [pass]: None
- **Chat template** [info]: No parent template to compare
- **Refusals modified** [pass]: No
- **License** [warn]: Declares other, but derives from a llama3.1 model whose terms carry over
- **Lineage** [pass]: Derives from fdtn-ai/Foundation-Sec-8B
- **Model card** [pass]: 5 of 6, missing evaluation results
- **Safetensors headers** [pass]: Every byte is indexed, no hidden data
- **Tensor layout** [info]: Vocabulary resized vs fdtn-ai/Foundation-Sec-8B

## Variants

- BF16 safetensors (safetensors, 16.1 GB)
