The Best Place to Build and Run AI with Ray
From the creators of Ray – Anyscale gives you a platform to run and scale all your ML and AI workloads, from data processing to training and inference.
Announcing First-Party Service on Azure Cloud
We’re excited to announce a new AI-native compute service co-engineered with Microsoft delivered as a fully managed, first-party offering on Azure. Now in private preview.
Ray is the Unified Compute Engine for the AI Era
Ray is an open-source framework that helps developers scale data processing, training, and inference workloads from laptops to tens or thousands of nodes.
- Python-native. Distribute Python functions using familiar frameworks and data structures.
- Multimodal. Process all data modalities, including images, video, text, audio, tabular datasets, and more.
- Heterogeneous. Coordinate task execution across CPUs, GPUs, or other accelerators in a single cluster.
Anyscale is the Best Platform for Ray
Ready from day one to help you build faster, scale easier, and operate with confidence.
DEVELOPER AGILITY
Build. Debug. Deploy. Repeat.
Interactive dev console with advanced workload observability to help you debug quickly, and seamlessly transition from dev to prod.
Built-in IDE. Cloud-based, scalable dev environments with idle termination to reduce costs accessible via VSCode, Jupyter, and Cursor.
Workload Observability. Debug faster with profiling tools built for distributed workloads.
Dependency Management. Auto propagate container and uv dependencies across Ray nodes.
PRODUCTION RESILIENCE
Deploy Anywhere. Scale Reliably.
Deploy fault-tolerant Ray clusters in your cloud of choice with built-in resilience, auto-scaling, and no manual ops.
Fault Tolerant. Heterogeneous (CPU/GPU) VM or K8s cluster deployments with proactive unhealthy node draining and replacement
Zero-downtime upgrades. Upgrade with confidence using built-in rollback and seamless transitions.
Monitoring & Alerting. Managed Prometheus and Grafana dashboards, backed by persistent logs.
COST EFFICIENCY
Keep GPUs Busy – and Budgets Lean
Boost performance with Anyscale optimizations. Efficiently manage jobs or users with built-in governance and cost controls.
Anyscale Runtime. Proprietary optimizations for every stage of the AI pipeline, from data preparation to training and inference.
Spot Instances. Reduce costs with reliable spot instance management, orchestration, and fall back to on-demand.
Cost Governance. Monitor usage across teams and keep costs in check with budgets and quotas.
One Platform. Every AI Workload.
From data prep to inference — if it’s Python, it runs better with Ray on Anyscale.
Starting with Ray for distributed AI/ML
Explore Ray core AI libraries, such as Ray Data and Ray Train, and learn how to use them for large-scale training and batch inference with GenAI and LLMs.
LLM training and inference
Fine-tune an LLM to perform batch inference and online serving for entity recognition.
Audio batch inference
Use LLMs as judges to curate and filter audio datasets for quality and relevance.
Reinforcement Learning for LLMs with SkyRL
Reinforcement Learning for LLMs using SkyRL and Ray.
Built with Ray. Deployed on Anyscale.
