Replicate is a cloud platform for running open-source AI models via a simple API. Thousands of models including Stable Diffusion, Llama, Whisper, and CodeLlama are available as hosted endpoints with pay-per-use pricing. Developers can push custom models using Cog, Replicate's containerisation tool for ML models. No GPU infrastructure management required. Ideal for startups and developers who want to integrate AI capabilities without building and maintaining their own model serving infrastructure.

RunPod is a cloud GPU platform that provides on-demand and spot GPU instances for AI model training, inference, and fine-tuning at competitive pricing with a simple deployment interface for containerized workloads. Its Serverless GPU product enables pay-per-second autoscaling inference endpoints that scale to zero when not in use, making it cost-effective for variable-traffic AI applications. AI startups, researchers, and developers building generative AI applications use RunPod to access affordable GPU compute with fast provisioning times and flexible pod configurations that match workload requirements without long-term commitments.

Google Vertex AI is Google Cloud's unified ML platform for building, deploying, and scaling AI models and applications. It provides access to Gemini models, AutoML, custom model training, vector search, model monitoring, and the Agent Builder for creating AI agents and RAG applications. Vertex AI Model Garden hosts 150+ foundation models from Google and third parties. Designed for enterprises building production AI systems on Google Cloud infrastructure with MLOps best practices built in.
