The Gemini API is Google's direct, first-party channel for the Gemini model family — 2.5/3.x Pro and Flash, plus the Flash-Image line — accessed through AI Studio with a personal API key.
Most current Gemini models are natively multimodal on input (text, image, audio, video), and a free tier is available for prototyping before moving to paid usage.
Google also serves the same underlying models through Vertex AI, its enterprise cloud channel — see that provider page for the difference.
Affiliate program: 5% commission per sale via Google Cloud's CJ Affiliate program. This is a Google-Cloud-wide program, not specific to the Gemini API, and self-serve signup is currently limited to the US and Canada. Program details
This is what Google Gemini API / AI Studio itself charges for each model — not the cheapest price across every provider (that's what the cards above show). Prompt tokens range $0.04–$2.00 per 1M across 3 priced models.

Latency: Per-provider latency isn't independently measured yet — the probe rig currently tests one route per model, not one per provider (see PROBE_RIG.md ledger #10).
