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 · Geminiunmatched practical knowledge of Solidity standards, upgradeability, access control, governance, and the widely used OpenZeppelin Contracts stack
  • maintaining foundational contract libraries Claude · Gemini · GPTmaintaining the web3 ecosystem's foundational contract libraries
  • long public track record Claudelong public track record auditing high-value systems
  • architecture and operational security GPTespecially 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 · Geminiexceptional cryptography, formal methods, fuzzing, protocol-design review

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.

Top alternatives per the models: Trail of Bits · Spearbit · Sherlock · Zellic
