What This Model Does

This model is purpose-trained to function as a debate agent — it can:

• Construct arguments for PRO or CON positions on any topic
• Rebut opponent arguments with logical counter-evidence
• Perform cross-examination with sharp, targeted questions
• Detect logical fallacies (ad hominem, straw man, false dichotomy, etc.)
• Cite reasoning chains rather than asserting unsupported claims

It is part of the Debate-AI project: a multi-agent debate system with separate specialized models for debating, fact-checking, and moderation.

Training Data

Trained on a mixed dataset of 35,000+ examples from:

• IBM Argument Quality corpus (30k human-annotated arguments)
• IBM Debate Speeches (human-scored opening speeches)
• args.me debate portal corpus (382k arguments, sampled)
• Reddit r/ChangeMyView, r/DebateReligion, r/PoliticalDiscussion threads
• Stanford Encyclopedia of Philosophy articles
• Wikipedia policy and ethics articles (80+ topics)
• FEVER fact-checking dataset

All data was filtered to quality score ≥ 3/5, deduplicated by content hash, and balanced across topic categories.
