Multi-LLM consensus engine. Pro £49/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.
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]
Every prompt passes through a fixed pipeline. Deterministic. Auditable. No black-box routing.
Yes, 13 named loops. The last three are housekeeping. Don't @ me.
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 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.
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.
Using the same logic behind the quorum heal self-repairing code daemon, Quorum scans hundreds of pages of contracts, detecting invisible loopholes and rewriting clauses before signatures are inked.
