Nobody is committing to one model vendor

Of the 45,274 repos that call a model provider's SDK directly, a fifth carry two. Counted from what is declared in package.json, pyproject.toml and requirements.txt — no inference.

27,186
OpenAI only
9,722
Both SDKs in the same repo
8,366
Anthropic only

That is 21% of everyone calling either one. Read the other way: 54% of repos using Anthropic also ship OpenAI, so the second SDK is usually added rather than swapped in.

Agent frameworks

GitHub Copilot5,460
Gemini CLI3,692

Counts committed config files, not market share: CLAUDE.md sits at the repo root, while .cursor/ is often gitignored. 103,034 repos have committed at least one; 33,549 have committed two or more.

Gateways and routers

A gateway makes the model provider a config value, so whatever it supports, these repos can reach.
