OpenZeppelin
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
OpenZeppelin appears in 1 AI-ranked category — best position #2 for smart contract audit firm.
Positioning brief — for the OpenZeppelin team
Why the models put OpenZeppelin at #2 for smart contract audit firm
- unmatched practical knowledge of Solidity standards GPT · Claude · Gemini“unmatched practical knowledge of Solidity standards, upgradeability, access control, governance, and the widely used OpenZeppelin Contracts stack”
- maintaining foundational contract libraries Claude · Gemini · GPT“maintaining the web3 ecosystem's foundational contract libraries”
- long public track record Claude“long public track record auditing high-value systems”
- architecture and operational security GPT“especially valuable when architecture and operational security matter alongside code defects”
What the models credit Trail of Bits (#1) with — and don’t credit OpenZeppelin
- cryptography, formal methods, fuzzing GPT · Gemini“exceptional cryptography, formal methods, fuzzing, protocol-design review”
- low-level security engineers Claude · Gemini“Deepest bench of low-level security engineers of any firm in the space”
- Solidity, Rust/Solana, Move, and node/client code Claude“audits span Solidity, Rust/Solana, Move, and node/client code”
What would move the rank — the models’ fix lines, unified
- queue long and pricing premium GPT · Claude · Gemini“Demand keeps the queue long and pricing premium”
- primary EVM focus GPT · Claude · Gemini“Premium fee structure and primary EVM focus”
- limited specialization for non-EVM ecosystems GPT · Claude · Gemini“limited specialization for non-EVM ecosystems like Solana or Move”

Audit arm sits next to the team that writes the contract libraries most protocols build on, giving unmatched context on upgradeability, proxy, and access-control pitfalls; long public track record auditing high-value systems (major L2s, governance, bridges) with clear, well-written reports.
Gemini Deepest domain mastery of EVM standards and secure smart contract architecture, drawing direct expertise from maintaining the web3 ecosystem's foundational contract libraries. Near-tie with Trail of Bits.
GPT Combines strong audits with unmatched practical knowledge of Solidity standards, upgradeability, access control, governance, and the widely used OpenZeppelin Contracts stack; especially valuable when architecture and operational security matter alongside code defects.
Where OpenZeppelin falls short, per the models
- GPT Expensive and sometimes difficult to schedule, while highly specialized ZK, consensus, or non-EVM work may fit a narrower specialist better.
- Claude Demand keeps the queue long and pricing premium; scope skews EVM/Solidity — less the pick for Solana, Move, or Cosmos-native codebases.
- Gemini Premium fee structure and primary EVM focus offer limited specialization for non-EVM ecosystems like Solana or Move.
