## How they compare

This is a hyperscaler choice more than a model choice. Both platforms carry Anthropic's Claude, so the real split is the rest of the catalog and the cloud around it. Vertex AI brings Google's own Gemini 3.8 family, Gemma, and media models like Imagen, Veo and Chirp, with 200+ models in Model Garden. Bedrock reaches 100+ models from 18+ providers, and since April 2026 that includes OpenAI models up to GPT-6 Astra. Both have added agent platforms on top: Vertex has Agent Studio, the Agent Development Kit and a managed runtime with Memory Bank, while Bedrock has AgentCore with session isolation, an MCP gateway and Cedar-based policies.

Pricing favors Bedrock on predictability. It offers on-demand, batch at 50% off and provisioned throughput at 20 to 40% off, though third-party analyses put most models 20 to 35% above direct prices (Claude is the exception, at parity). Vertex pricing is usage-based and split across every service, which reviewers call hard to forecast. The deciding factor is usually where your data and security model already live. BigQuery shops and teams that train custom models on TPUs get more from Vertex. Teams whose posture is built on IAM, PrivateLink, KMS and CloudTrail get GPT and Claude on Bedrock without adding a vendor.

## 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.

### Amazon Bedrock

Amazon Bedrock is AWS's managed model service and has become the default AI control plane for many enterprises. One API reaches 100+ models from 18+ providers, including Anthropic's Claude family, Meta, Mistral, DeepSeek, Amazon's own Nova models, and, since an April 2026 partnership expansion, OpenAI models up to GPT-6 Astra. Switching models is usually just a new model ID. Every call inherits IAM, PrivateLink, KMS encryption and CloudTrail logging, and provider models never train on customer data.

## Which is best, and when

### Choose Google Vertex AI for

- Gemini 3.8 and Claude side by side on Google Cloud
- Teams whose data already sits in BigQuery
- Custom training on TPUs or GPUs next to inference

### Choose Amazon Bedrock for

- GPT-6 Astra and Claude under one AWS bill
- Regulated teams standardized on IAM, KMS and CloudTrail
- Provisioned throughput discounts for steady traffic
