Modal vs Replicate
Updated March 10, 2026
Overview
Modal is a serverless cloud platform for running AI workloads with zero infrastructure management. Developers write Python code and Modal handles containerization, GPU provisioning, scaling, and scheduling automatically. The platform supports GPU-accelerated functions, scheduled jobs, web endpoints, and batch processing, making it particularly popular for ML pipelines, model serving, and data processing tasks.
Replicate is a platform for running AI models in the cloud with a simple API. It hosts thousands of open-source models including Llama, Stable Diffusion, and Whisper, letting developers run them with a single API call. Replicate handles GPU provisioning, scaling, and model optimization automatically.
