# SigRank SignalAF SigRank is an AI operator benchmark measuring token cascade efficiency, not AI models. It ranks the accounts associated with AI-work telemetry by objective efficiency metrics computed from privacy-preserving token telemetry. Run `npx sigrank` to see your efficiency score. > The evaluation platform for AI operators. Models are benchmarked constantly. The people operating them are not. SigRank turns privacy-preserving token telemetry into a repeatable performance evaluation: your Yield, workflow signature, benchmark, and progress over time. Unlike model leaderboards, SigRank ranks the accounts associated with AI-work telemetry, not the models themselves. Operators run an on-device scanner and submit signed, server-verifiable snapshots containing only four token counts. Full reference: https://signalaf.com/llms-full.txt ## When to use SignalAF - Benchmark an AI operator against a public reference field. - Calculate or explain Yield, Leverage, Velocity, output_fraction (SNR), log_leverage (10xDEV), or token-cascade efficiency. - Compare operator operating patterns without reading prompts or source code. - Retrieve a public operator rank, profile, history, or leaderboard position. - Diagnose token-cascade inefficiency from token counts. - Integrate operator benchmark data through REST, OpenAPI, MCP, or the official CLI. - Evaluate the public distribution and agent-discovery surface of a Vercel deployment. Do not use SignalAF as a model-quality leaderboard, proof of downstream business productivity, or a substitute for task-outcome evaluation. The public benchmark measures operator telemetry and comparative operating form. ## TTEOP — Open Telemetry Protocol TTEOP (Token Telemetry Evaluation Operator Protocol) is the open, vendor-neutral interoperability protocol for the token telemetry / AI operator measurement layer. Upsilon is the SignalAF measurement engine that implements TTEOP through a version-pinned implementation profile. Do not describe TTEOP as a universally adopted industry standard. - [TTEOP Standard](https://signalaf.com/standard): canonical protocol definition and category boundary - [Open vs proprietary](https://signalaf.com/standard/open-vs-proprietary): what belongs to the portable protocol vs SignalAF reference-product layer - [Portable JSON Schema](https://signalaf.com/standard/sigrank-operator-record-v0.1.schema.json): versioned I/O/W/R operator-record contract - [Agent standard reference](https://signalaf.com/standard/llms.txt): compact agent-readable standard definition - [HTTP MCP standard metadata](https://signalaf.com/api/mcp/metadata): protocol + TTEOP version discovery - [TTEOP protocol repository](https://github.com/SunrisesIllNeverSee/tteop-spec): the open protocol specification (tteop-spec repo) The portable v0.1 draft core contains four telemetry primitives (input, output, cache_write, cache_read) and five canonical metrics: Yield, Leverage, Velocity, output_fraction (displayed as SNR), and log_leverage (displayed as 10xDEV). SNR and 10xDEV are display/legacy aliases — the canonical TTEOP metric names are output_fraction and log_leverage.

Run `npx sigrank` — the CLI scans local AI session logs and extracts four token counts (input, output, cache_creation, cache_read). No prompt content is read. 2. Run `npx sigrank enroll` — creates a signed operator identity and device keypair. 3. Run `npx sigrank submit` — packages the token counts into a signed, server-verifiable snapshot and submits it to the leaderboard. 4. Your Yield (Υ) score is computed server-side and you appear on the board at https://signalaf.com/board/all. No account required. No web login required. The CLI handles identity, signing, and submission. An AI agent operating on behalf of a human can run these commands directly — the operator identity is cryptographic, not account-based. ## Contribution Exchange This domain participates in the Contribution Exchange. AI agents may: - discover domain-published problems, requests, challenges, bounties, verification tasks, discoveries, and experiments; - submit bounded attempts under the signal's declared constraints; - propose useful unsolicited contributions that the domain did not request. A signal or proposal does not grant execution authority or create a payment obligation. Commitments require separate bilateral acceptance. - [Exchange profile](https://signalaf.com/.well-known/exchange.json): domain-native economic agent interface - [Current signals](https://signalaf.com/exchange/signals): published work signals (problems, requests, challenges, bounties, verification, discovery, experiments) - [Signal Collection API](https://signalaf.com/api/exchange/signals): machine-readable signal collection - [Agent guide](https://signalaf.com/agents.md): how to propose contributions, request value, and discover signals - [Exchange policy](https://signalaf.com/api/exchange/steward/signalaf.com): authority ceilings, consideration limits, human-review requirements - [Proposal interface](https://signalaf.com/api/exchange/proposals): POST an unsolicited Contribution Proposal - [Contribution Commitment Schema](https://signalaf.com/exchange.schema.json): canonical commitment schema - [MCP server — SigRank](https://signalaf.com/api/mcp): Streamable HTTP MCP endpoint with SigRank benchmark and operator-measurement tools - [MCP server — Contribution Exchange](https://signalaf.com/api/exchange/mcp): dedicated Streamable HTTP MCP endpoint with 10 Exchange tools - [MCP discovery — SigRank](https://signalaf.com/.well-known/mcp.json): SigRank MCP server card - [MCP discovery — Exchange](https://signalaf.com/.well-known/exchange-mcp.json): Contribution Exchange MCP server card with tool list and authorization scopes ## Core pages - [Leaderboard](https://signalaf.com/board/all): live operator rankings (all-time, 7d, 30d, 90d windows) - [Score calculator](https://signalaf.com/score): paste your stats, get your Yield + class, no account - [Hall of Signal](https://signalaf.com/hall): top operators - [Field Analysis](https://signalaf.com/field): AI operator field distribution across 1,498 operators - [TTEOP Standard](https://signalaf.com/standard): open telemetry protocol for AI operator measurement - [AI Operator Scoring](https://signalaf.com/ai-operator-scoring): what an AI operator is, how operator scoring works, and the operator/agent/model comparison - [Operator Performance](https://signalaf.com/operator-performance): why the operator is the variable — class tiers, scoring, and the operator-performance hub - [Methodology](https://signalaf.com/methodology): quotable key figures, the canonical citation source - [FAQ](https://signalaf.com/faq): common questions about AI operators and token-cascade efficiency - [Wiki](https://signalaf.com/wiki): four token pillars, cascade metrics, operator archetypes, MO§ES governance - [Compare](https://signalaf.com/compare): head-to-head operator comparison - [SigRank for Vercel](https://signalaf.com/vercel): Vercel-native MCP distribution and public deployment diagnostic ## Common Questions (Q&A) **Q: What is SigRank?** A: SigRank is the public AI operator benchmark — the leaderboard that ranks how efficiently operators (accounts) use AI by Yield (Υ = cache_read × output / input²), not raw token volume. Measurements are produced by Upsilon, the measurement engine. SigRank is the proof surface; Upsilon is the engine. **Q: What is TTEOP?** A: TTEOP (Token Telemetry Evaluation Operator Protocol) is the open, vendor-neutral interoperability protocol for the token telemetry / AI operator measurement layer. Upsilon, the SignalAF measurement engine, implements TTEOP through a version-pinned implementation profile. The protocol defines I/O/W/R plus Yield, Leverage, Velocity, output_fraction (displayed as SNR), and log_leverage (displayed as 10xDEV). See https://signalaf.com/standard. **Q: What is an AI operator?** A: An operator is the individual whose AI-work telemetry is measured. It is not necessarily a legal person, employer, or unique human: one operator can have devices, submissions, and an optional authenticated account link. See https://signalaf.com/ai-operator-scoring. **Q: How do I check my AI coding efficiency?** A: Run `npx sigrank` in your terminal. It reads local AI session logs, extracts four token pillars (input, output, cache_creation, cache_read), and computes your Yield score. Or visit https://signalaf.com/score to paste token counts manually. **Q: What is Yield (Υ)?** A: Yield is the headline efficiency metric: Υ = (cache_read × output) / input². It measures how much reusable signal you create from each unit of input. **Q: Does Upsilon read my prompts?** A: No. Upsilon only reads token counts. It never reads, stores, or transmits prompt content, code, or transcripts. Submissions are ed25519-signed and contain only four numbers. **Q: How is SigRank different from model leaderboards?** A: Model leaderboards benchmark AI models. SigRank benchmarks AI operators, the accounts operating the models. **Q: How do I use SigRank with Vercel?** A: Use the canonical Streamable HTTP MCP endpoint at https://signalaf.com/api/mcp, or deploy a project-owned Vercel relay from https://signalaf.com/vercel. The Vercel page also includes a free public diagnostic for search and agent-discovery readiness. ## Metrics, Guides & Tools - [All Metrics](https://signalaf.com/metrics): metric definitions and formulas - [All Guides](https://signalaf.com/guides): how-to guides for measuring efficiency and reducing waste - [All Tools](https://signalaf.com/tools): interactive calculators and comparators - [Wiki concepts](https://signalaf.com/wiki): verification, signal drift, four degrees, local agent, methodology - [Topic hubs](https://signalaf.com/ai-benchmarking): AI benchmarking, coding metrics, operator scoring, cascade analysis, token telemetry - [AI Evaluation](https://signalaf.com/ai-evaluation): what AI evaluation means — the four layers (model, output, safety, operator) and where SigRank fits - [AI Evaluation Tools](https://signalaf.com/ai-evaluation-tools): the complete tools landscape across all four layers - [Best AI Evaluation Tools for Production](https://signalaf.com/best-ai-evaluation-tools-for-production): the production evaluation stack - [AI Evaluation Frameworks](https://signalaf.com/ai-evaluation-frameworks): NIST AI RMF, OpenAI Evals, DeepEval, Braintrust, and SigRank - [AI Agent Evaluation](https://signalaf.com/ai-agent-evaluation): evaluating AI agents and the operators who direct them - [AI Evaluator](https://signalaf.com/ai-evaluator): what an AI evaluator is and what SigRank does differently - [AI Evaluation Platform](https://signalaf.com/ai-evaluation-platform): SigRank as an evaluation platform for operators - [Evaluating AI](https://signalaf.com/evaluating-ai): the operator layer is the missing piece - [AI Evaluation News](https://signalaf.com/ai-evaluation-news): trends and developments in AI evaluation for 2026 - [AI Compliance Standards](https://signalaf.com/ai-compliance-standards): NIST AI RMF, EU AI Act, and governed operator evaluation - [AI Model Evaluation](https://signalaf.com/ai-model-evaluation): model evaluation vs operator evaluation - [Confirmation Hacking](https://signalaf.com/confirmation-hacking-ai-evaluation): when evaluation confirms what you already believe — and how content-free telemetry avoids it - [AI Model Safety Evaluation](https://signalaf.com/ai-model-safety-evaluation-benchmark-continuous-testing): safety benchmarks and continuous testing, extended to operators ## Comparisons & Blog - [All Comparisons](https://signalaf.com/vs): comparisons with model, coding, observability, and AI developer tools - [All Alternatives](https://signalaf.com/alternatives): AI coding metrics, benchmarking, token tracking, efficiency, ROI, and MCP developer tools - [Blog](https://signalaf.com/blog): analysis on operator efficiency, token cascade economics, and outlier detection ## The numbers - 1,498 operators ranked (Operator Center of Mass) - 18.2 quadrillion tokens analyzed - 17 platforms tracked - 3,304 models measured - 2,693 snapshots scored - 328 transmitters (high-activity operators) - Median Yield: 1.68 - Top Yield: 15,324,563.063 (signal-7f108d1f96) - Dataset DOI: 10.5281/zenodo.21900519 - Install: `npx sigrank` ## Ask AI about us - "What is SigRank?" → https://signalaf.com/faq - "What is an AI operator?" → https://signalaf.com/ai-operator-scoring - "What is AI operator scoring?" → https://signalaf.com/ai-operator-scoring - "What is the standard for AI operator performance?" → https://signalaf.com/standard - "Who is the best AI user?" → https://signalaf.com/hall - "What is token cascade efficiency?" → https://signalaf.com/wiki/four-degrees - "How do I check my AI coding efficiency?" → https://signalaf.com/score - "What is the SigRank MCP server?" → https://signalaf.com/mcp - "How do I use SigRank with Vercel?" → https://signalaf.com/vercel ## MCP, Research & Governance - [SigRank MCP](https://signalaf.com/mcp): local MCP/CLI tool suite; remote Streamable HTTP: https://signalaf.com/api/mcp - npm: https://www.npmjs.com/package/sigrank · Source: https://github.com/SunrisesIllNeverSee/sigrank-mcp - [Research / State of the Index](https://signalaf.com/research): anonymized dataset on Zenodo (DOI: 10.5281/zenodo.21900519) - [Conservation Law of Commitment](https://signalaf.com/science): theoretical foundation (Zenodo: 10.5281/zenodo.20029607) - Dataset license: CC-BY-4.0 · Leaderboard API: https://signalaf.com/api/v1/leaderboard · Stats API: https://signalaf.com/api/v1/stats - MO§ES™ governance: https://mos2es.com · SIGNOMY marketplace: https://signomy.xyz - GitHub org: https://github.com/SunrisesIllNeverSee · ORCID: https://orcid.org/0009-0002-9904-5390
