Developers also use this package with other vendors, because those vendors copy OpenAI's API. The true OpenAI number is lower.

Sourcegraph renamed this package in May 2026. This line adds @sourcegraph/amp and @ampcode/cli together, so it stays continuous.

Model-vendor adapters (Vercel AI SDK)

Each package connects the Vercel AI SDK to one model vendor. The lines compare vendors, but only inside JavaScript projects that use this SDK.
