What is 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.
The platform goes far past inference. Agent Studio covers low-code agent building, the Agent Development Kit handles code-first agents, and a managed agent runtime with Memory Bank handles deployment and cross-session memory, with Agent2Agent protocol support for interop. The older MLOps foundation remains: custom training on GPUs or TPUs, pipelines, a feature store, model registry, evaluation, vector search and deep BigQuery integration. Pricing is usage-based and split across every service, and new accounts get up to $300 in credits.
Google Vertex AI pros, cons and use cases
Upsides
- Gemini and Claude side by side, next to training, MLOps and governance in one stack.
- Deep BigQuery integration keeps models close to enterprise data.
Core use cases
- Enterprises on Google Cloud building governed production agents.
- Long-context and multimodal work on Gemini, including video.
Downsides
- Fragmented, hard-to-forecast pricing and a sprawling product surface with names in flux.
- Real lock-in, since pipelines, features and registries are Vertex-native, and support often draws unfavorable comparisons with AWS.
