# Which AI API SDKs developers installed in August 2026

Published 2026-09-01 · covers August 2026

In August 2026, google had the most-installed first-party AI API SDK at 336,160,425 downloads across PyPI and npm. Installs are not latency — they are the other question a developer asks: is anyone actually using this. Which AI provider SDKs were installed most?

Because it is the client of a protocol , not of a vendor. Groq, Together, DeepInfra, OpenRouter and most others document their own APIs through it, so its download count measures how far the OpenAI-compatible interface has spread, not how much OpenAI is used. Counting it as one provider’s popularity would be the single easiest way to publish a wrong number here, so it is reported separately and never ranked.
