Which platform is best for training large models?

For training large foundation models or fine-tuning LLMs, the key factors are GPU availability, distributed training frameworks, and interconnect bandwidth. AWS SageMaker supports distributed training with EFA networking and p5/p4d instances (H100/A100). Azure ML integrates with ND H100 VMs and InfiniBand networking for large-scale training. GCP Vertex AI provides A3 (H100) instances with GPUDirect-TCPX and tight TPU integration for massive scale. OCI Data Science offers A100 GPU shapes with high-bandwidth RDMA networking. GCP's TPU access is unique and cost-effective for transformer architectures. For GPU training, all four are competitive — choose based on GPU availability in your region and existing cloud investments.

How do the foundation model marketplaces compare?

AWS Bedrock provides access to models from Anthropic, Meta, Mistral, Cohere, and Amazon Titan with a unified API. Azure OpenAI offers exclusive access to OpenAI models (GPT-4, DALL-E, Whisper) with enterprise security. GCP Vertex AI Model Garden hosts 150+ models including Gemini, Llama, and Mistral with one-click deployment. OCI Generative AI offers models from Cohere and Meta with dedicated GPU serving. The choice often depends on which model provider you need — Azure for OpenAI exclusivity, Bedrock for Anthropic Claude, Vertex AI for Gemini, or any platform for open-source models like Llama.
