Modal Labs

Modal LabsSince 2022-11

Modal Labs is a high-performance serverless cloud platform that enables AI engineers and developers to run Python code in the cloud with instant access to thousands of CPUs, GPUs, and persistent network volumes. Founded by former Spotify CTO Erik Bernhardsson, Modal reimagines cloud computing with sub-second cold starts and zero infrastructure configuration. With Modal, you define your container image, dependencies, and GPU hardware directly inside standard Python code using simple decorators (e.g. `@app.function(gpu="H100")`). Modal handles container building, volume mounting, GPU scheduling, and automatic scaling down to zero in milliseconds, making it the premier choice for running generative AI models, ComfyUI video pipelines, and massive parallel batch jobs.

Modal operates a custom container runtime built in Rust that bypasses standard Docker daemon overhead, allowing container images to spawn in under 900 milliseconds. Its distributed filesystem mounts shared NetworkFileSystem (NFS) volumes across thousands of simultaneous workers with near-local NVMe read speeds. Modal supports NVIDIA T4, L4, A10G, A100 (40GB/80GB), and H100 SXM5 GPUs. Developers can attach web endpoints (`@app.web_endpoint`), schedule recurring cron tasks, execute distributed map-reduce jobs across tens of thousands of cores, and monitor live streaming logs via the interactive web console.

NVIDIA DGX Cloud LeptonSince 2023-08

NVIDIA DGX Cloud Lepton (formerly Lepton AI, acquired by NVIDIA) is an AI-centric compute marketplace and model serving platform that connects developers to tens of thousands of GPUs across a global network of NVIDIA Cloud Partners (including CoreWeave, Lambda, and tier-1 clouds). Founded by Yangqing Jia (creator of Caffe) and acquired by NVIDIA, DGX Cloud Lepton functions like a high-performance compute marketplace for AI engineering teams. It allows developers to discover available GPU compute across regions and seamlessly deploy, fine-tune, and scale AI workloads with zero Kubernetes overhead.

DGX Cloud Lepton integrates directly with the full NVIDIA enterprise software stack, including NVIDIA NIM (Inference Microservices), NeMo, and NVIDIA Cloud Functions. Developers use Python Photons and simple CLI commands to turn arbitrary PyTorch scripts into auto-scaling microservices running on NVIDIA H100, H200, and Blackwell B200 clusters. The platform provides heterogeneous multi-cloud abstraction, automatic load balancing, scale-to-zero serverless runtimes, and distributed key-value storage, giving enterprise teams instant access to reserved and spot GPU capacity with guaranteed NVIDIA driver and CUDA acceleration.
