  "shortTitle": "Agent model share",
  "topic": "agentic",
  "abstract": "How much of coding agent spend goes to Claude? In April 2026, Claude models power 79% to 100% of spend across all nine coding agents observed through the Requesty gateway. Claude Code is nearly 100% locked to Claude (expected, as Anthropic's own product). Zed is the most model-diverse at 59% Claude / 41% OpenAI. OpenCode has the highest non-Claude adoption among open-source agents at 13% OpenAI.",
  "whyItMatters": "The near-total consolidation to Claude occurred organically across agents whose users freely choose their backend model. This is a revealed preference: when developers can pick any model for coding tasks, they overwhelmingly choose Claude. Gemini's share has declined from 34% (May 2025 via Cline) to under 6% across all agents, despite competitive pricing.",
  "questions": [
    "Which AI model do coding agents use most?",
    "What percentage of coding agent spend goes to Claude?",
    "Do coding agent users prefer Claude over GPT for coding?",
    "Which coding agent has the most model diversity?",
    "Why is Claude so dominant in AI coding tools?"

  "caveats": [
    "Share is measured by spend, not request count. High-cost models appear larger in spend share.",
    "Cursor and GitHub Copilot have minimal representation because they primarily connect directly to providers.",
    "Model share reflects user choice, not agent defaults. Most agents allow users to configure any model."
  ],
  "keyFindings": [
    "Claude Code: 99.5% Claude. Expected, as it is Anthropic's first-party tool.",
    "Roo Code: 92% Claude. Open-source, model-agnostic, yet users overwhelmingly choose Claude.",
    "OpenCode: 79% Claude, 13% OpenAI. The most experimental open-source user base.",
    "Zed: 59% Claude, 41% OpenAI. The most model-diverse agent overall.",
    "Gemini share is below 6% across all agents despite competitive pricing."
