What Modal does
Modal is a developer-first, serverless compute and infrastructure platform purpose-built for AI workloads. Modal’s core value proposition is that engineers can write application logic (including model inference, fine-tuning/training jobs, and other AI pipelines) using a code-first workflow, then scale from small runs to thousands of CPUs/GPUs without managing infrastructure.

Modal positions this as “cloud built for AI,” emphasizing primitives tailored to inference latency, secure execution of untrusted/agent-generated code, and scaling dynamics typical of modern ML workflows. Modal sells usage-based compute and higher-level platform capabilities (e.g., inference serving primitives, sandboxed execution for agents, and managed runtime primitives) to teams building production AI systems.
