If you're choosing a cloud provider for enterprise AI/ML workloads in 2026, the decision comes down to three: AWS SageMaker, Google Cloud Vertex AI, or Microsoft Azure Machine Learning.
All three offer model hosting, custom training, MLOps, and access to frontier models. But the differences in pricing, model access, and developer experience can swing your total cost of ownership by 40-60% and your team's productivity by weeks per project.
⚡ Quick Decision Guide
- [OpenAI](/tools/openai-frontier)-focused? → Azure OpenAI Service (enterprise SLA)
- [Claude](/tools/claude) + multi-model? → AWS Bedrock (widest selection)
- [Gemini](/tools/gemini) 3 + BigQuery? → GCP Vertex AI (native integration)
- Cost optimization? → AWS (spot instances save 70-90%)
- Microsoft shop? → Azure (bundled discounts)
Here's the data-driven breakdown.
Model Hosting & Access: Who Has Which Models?
| Provider | Available Models | Exclusive Access | Winner For |
|---|---|---|---|
| AWS SageMaker | GPT-5.4, Claude Opus/Sonnet, Llama 3.3, Cohere, Mistral, Stability AI, Amazon Titan | Amazon Titan models | 🏆 Widest selection, multi-model strategies |
| Google Vertex AI | Gemini 3 Pro, Claude, Llama 3.3, Mistral, Imagen, Chirp, Veo | ✨ Gemini 3 (2M context, video) | 🏆 Multimodal AI, BigQuery users |
| Azure ML | GPT-5.4, o3, GPT-5 mini, Llama 3.3, Mistral, Cohere | ✨ OpenAI enterprise SLA | 🏆 OpenAI + Microsoft ecosystem |
⚠️ Key Limitation: No provider offers all frontier models. Azure lacks Claude, GCP lacks GPT-5.4. Only AWS offers both OpenAI and Anthropic.
