Quorum

Multi-LLM consensus engine. Pro £149/mo for solo devs.

One prompt, N models, a scored verdict. Quorum is a vendor-neutral consensus engine that asks frontier LLMs the same question, measures agreement, and tells you when they disagree — so you stop trusting a single oracle.

30-second demo

A real session, lightly trimmed. No hand-waving.

$ quorum ask "What is L-Cysteine?" --models gpt5,claude4,gemini3,llama4,grok3
[*] fanning out to 5 backends... 1.8s

gpt5           Non-essential proteinogenic amino acid. Thiol side chain (-SH).
                Precursor to glutathione; used in keratin disulfide bonds.
claude4        Sulfur-containing alpha-amino acid (C3H7NO2S). Forms disulfide
                bridges via cysteine residues; key in hair/keratin structure.
gemini3        Semi-essential amino acid. Contains a thiol group, central to
                redox biology, glutathione synthesis, and protein folding.
llama4-local   Amino acid w/ -SH group. Important in keratin (hair), antioxidant
                pathways, and NAC (N-acetyl-cysteine) supplements.
grok3          Sulfur amino acid. Builds disulfide bonds in keratin; precursor
                of glutathione; semi-essential in humans.

[*] scoring agreement (Jaccard + semantic embed)...

  consensus     0.91   (strong agreement on 4/5 claims)
  divergence    0.09   essential vs semi-essential (gpt5 vs gemini3/grok3)
  verdict       CONSENSUS  use synthesis below; flag the divergence

> synthesis  L-Cysteine is a sulfur-containing amino acid (thiol -SH side
            chain) that forms disulfide bonds in keratin, is a precursor
            to glutathione, and is generally classified as semi-essential
            in humans. [disputed: gpt5 says non-essential]

The 13 loops

Every prompt passes through a fixed pipeline. Deterministic. Auditable. No black-box routing.

01 / intakeNormalize prompt, strip PII, attach context.
02 / classifyDomain tag: code, med, legal, math, chat.
03 / policyApply jurisdiction + vendor allowlist.
04 / fanoutDispatch to N backends in parallel.
05 / collectBounded wait, partial-tolerant.
06 / normalizeStrip refusals, unify whitespace, dedupe.
07 / embedLocal embeddings, no vendor leak.
08 / scoreLexical (Dice) + semantic (cosine).
09 / clusterGroup answers, surface minority view.
10 / verdictCONSENSUS / SPLIT / NO-ANSWER.
11 / synthesizeCompose final answer, mark disputes.
12 / traceHash + sign run, tamper-evident traceability log.
13 / billPer-token, per-backend, per-tenant.
14 / feedback(opt-in) Update calibration priors.
15 / decayDrop stale evidence after TTL.
16 / exportJSON, JSONL, SARIF, PDF.

Yes, 13 named loops. The last three are housekeeping. Don't @ me.

Zero-Risk Enterprise Consensus

Would you trust a $10M trade or a cancer diagnosis to a single human analyst? If the answer is no, why are you trusting your critical enterprise data to a single AI model?

AI hallucinates. It makes silent errors. In high-stakes markets, a single hallucination costs millions. Quorum forces the world's most powerful AIs (Claude, GPT, Gemini) to debate each other, spot each other's flaws, and only deliver a result when they reach "Zero-Error" consensus.

A fracturing single AI node vs a secure, unified Quorum swarm shield.
Quorum orchestrating medical and financial data.

🏥 Healthcare

A false positive in an MRI scan can cost lives. Quorum routes medical imaging to 3 specialized models. If Model A diagnoses a lesion but Model B disagrees, an Autonomous Debate resolves the divergence before a final report is issued.

💰 Finance & Hedge Funds

Quorum orchestrates dense financial reports. While one model extracts raw data, another analyzes market sentiment, and a third acts as the "Judge", vetoing ghost metrics hallucinated by a single node.

⚖️ Legal Document Review

Using the same logic behind the quorum heal self-repairing code daemon, Quorum scans hundreds of pages of contracts, surfacing ambiguous clauses and inconsistencies as advisory technical input for human legal review. Not legal advice; lawyer review still required.
