Arbiter — T5 cybersecurity Q&A

What this is

A T5 conditional-generation checkpoint fine-tuned for Arbiter.

Used for general cybersecurity questions (phishing, ransomware, DDoS, etc.) when the input is not classified as a structured log. The app returns a short generated answer via T5ForConditionalGeneration.generate(...).

Project

Part of Arbiter (Django + React): paste a security log or ask a cybersecurity question.

This repository holds weights only. Application code: github.com/SentinelSage/arbiter.

Training note

This is a custom fine-tune, not an unmodified public T5 base/small checkpoint. A generic Hub T5 model is not a guaranteed substitute for this artifact.

Training data: custom-curated, unpublished project data. Training tables are not published with the app.

Intended use

• Running the Arbiter full-ML path locally
• Experimentation and educational use with the companion application

Not a production SOC product. No warranty. Generated text can be incomplete or incorrect; do not use for live security operations without your own validation.

How Arbiter loads it

Local path after download:

backend/models/cyber_qa_t5_model_general/

Loaded with T5ForConditionalGeneration.from_pretrained(<local_or_hub_id>) when ARBITER_DEMO_MODE=false.

Files

Expect a standard Transformers export, e.g. model.safetensors, config.json, spiece.model, tokenizer config files.
