Google adds AlphaEvolve agent as a billed SKU on Vertex AI
Google added AlphaEvolve, the DeepMind evolutionary coding agent, to Vertex AI pricing, billed as the Gemini model rate plus a 2x agent surcharge (3x all-in), e.g. 6 USD / 36 USD per 1M on Gemini 3.1 Pro Preview.
Vertex AI billed Gemini models on Standard/Priority/Flex token rates only; no AlphaEvolve line item.
AlphaEvolve agent priced as base Gemini model plus a 2x agent surcharge (total 3x base): Gemini 3.1 Pro Preview 6 USD/1M input, 36 USD/1M output; Gemini 3.5 Flash 4.50 USD/1M input, 27 USD/1M output.
Proof of change
Google's pricing pages, as we captured them on two dates.
These values appear in only one of the two captures. That can mean a page-layout difference rather than a price move — read the images, not just the list.

The Vertex AI generative-AI pricing page gained a new AlphaEvolve agent SKU during the week of 2026-07-14. AlphaEvolve is the DeepMind evolutionary coding/optimization agent, and it is billed as a composite of two charges: the underlying Gemini model standard token rate plus a separate AlphaEvolve agent surcharge equal to 2x the base model rate. The all-in cost is therefore 3x the standard model price.
Two underlying models are published:
- Gemini 3.1 Pro Preview — 2 USD model + 4 USD agent = 6 USD per 1M input tokens; 12 USD model + 24 USD agent = 36 USD per 1M output/thinking tokens.
- Gemini 3.5 Flash — 1.50 USD model + 3 USD agent = 4.50 USD per 1M input tokens; 9 USD model + 18 USD agent = 27 USD per 1M output/thinking tokens.
Headline Gemini API and Vertex AI token prices were verified unchanged versus the 2026-07-06 capture, and the consumer Google AI Plus / Pro / Ultra subscription lineup was also unchanged. The AlphaEvolve addition is the only new billable line item this run.
Google added AlphaEvolve, DeepMind's evolutionary coding/optimization agent, as a separately-billed agentic SKU on the Vertex AI pricing page. Its cost is the underlying Gemini model rate plus an AlphaEvolve agent surcharge (agent = 2× base model, so the all-in total is 3× standard): e.g. Gemini 3.1 Pro Preview totals $6/1M input and $36/1M output; Gemini 3.5 Flash totals $4.50/1M input and $27/1M output. Headline Gemini API and Vertex token prices were verified unchanged vs 2026-07-06; the consumer AI Plus/Pro/Ultra lineup was also unchanged.
