# Google Vertex AI vs DeepSeek

> Google's governed AI platform against a Chinese open-weight lab with rock-bottom first-party prices. The call turns on data location, price and whether you need a platform or a model.

## How they compare

DeepSeek's first-party API is about price. It serves two models, V4.1 Flash and V4 Pro, both with 1M context and 384K max output, at $0.30 in and $1.20 out and $1.32 in and $3.96 out at peak, with every off-peak hour at exactly half. Cache hits cost a few cents per million or less. Vertex AI is a platform, not a model: Gemini 3.8, Claude and 200+ models in Model Garden, with training, evaluation, vector search and agent tooling on Google Cloud. Its pricing is harder to forecast, but it comes with Google Cloud's enterprise controls.

Data location is often the hard stop. DeepSeek's hosted API stores data in China, which rules it out for many enterprises, and frequent retirements and repricing keep cost models in flux. The weights are MIT licensed, though, so teams can self-host or fine-tune them, and most other hosts serve DeepSeek too. For a Google Cloud enterprise, Vertex is the safer default. For cost-sensitive agents and batch jobs that can run off-peak, where the data is allowed to leave the region, DeepSeek's own API is hard to beat.

## What each one does

### Google Vertex AI

Vertex AI is Google Cloud's enterprise AI platform. At Google Cloud Next on April 22, 2026, Google rebranded it the Gemini Enterprise Agent Platform with an agent-first structure, though the API endpoint and most docs still say Vertex. Model Garden offers 200+ models, including Google's Gemini 3.8 family, Anthropic's Claude models and open models like Gemma, alongside Imagen, Veo and Chirp for media and speech. Google's own TPUs sit underneath much of its first-party serving.

### DeepSeek

DeepSeek is the Chinese lab whose open-weight models reset price expectations for the whole market. Its API now serves two models, both with 1M context and 384K max output. V4.1 Flash shipped September 10, 2026 with built-in image understanding at $0.30 in and $1.20 out at peak. V4 Pro, generally available since August 13, costs $1.32 in and $3.96 out at peak. Cache hits cost a few cents per million or less, and the weights ship on Hugging Face under an MIT license.

## Which is best, and when
