Validate the Thought,
Not Just the Answer.
LLMs can arrive at correct answers through flawed reasoning. QWED's Reasoning Engine validates every step of a Chain-of-Thought pipeline, ensuring logical coherence from premise to conclusion.

Why CoT Verification Matters
Chain-of-Thought prompting makes LLMs more powerful—but also more dangerously convincing when they reason incorrectly. A correct final answer doesn't mean the reasoning is sound.
Step-by-Step Audit
Each reasoning step is isolated, validated for logical consistency, and cross-referenced against known constraints and prior steps.
Multi-Provider Consensus
Cross-validate reasoning across multiple LLM providers. If GPT-4 and Claude disagree on a step, QWED flags the divergence for review.
Result Caching
Identical reasoning chains are cached and reused, significantly reducing latency and API costs for repeated queries.
How the Engine Works
Breaking reasoning into verifiable atomic steps.
CoT Decomposition
Parses LLM reasoning into discrete logical steps with dependency tracking.
Step Validation
Each step is checked for logical consistency, factual accuracy, and coherence with prior steps.
Consensus Engine
Multi-provider cross-validation confirms reasoning stability across different models.
Verdict & Cache
Returns a confidence score per step. Valid chains are cached for instant future lookups.
Where Reasoning Verification Matters
Any domain where the "why" matters as much as the "what." When a model explains its decision, you need to know the explanation is sound—not just persuasive.
Legal Analysis
Validate that AI-generated legal reasoning follows from cited statutes and precedents without logical leaps.
Medical Diagnosis
Ensure diagnostic reasoning follows clinical guidelines and doesn't skip critical differential diagnosis steps.
Education & Tutoring
Verify that AI tutors explain steps correctly, not just arrive at the right answer through flawed logic.
