Nobody is committing to one model vendor

Of the 41,108 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.

24,995
OpenAI only
8,947
Both SDKs in the same repo
7,166
Anthropic only

That is 22% of everyone calling either one. Read the other way: 56% of repos using Anthropic also ship OpenAI, so the second SDK is usually added rather than swapped in.

GitHub Copilot4,886
Gemini CLI2,986

Counts committed config files, not market share: CLAUDE.md sits at the repo root, while .cursor/ is often gitignored. 86,586 repos have committed at least one; 27,419 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.
