Determined AI
Open-source ML training platform providing distributed training, automated hyperparameter search, experiment tracking, and GPU cluster management. Determined optimizes GPU utilization across teams with preemptible scheduling, gang scheduling for distributed jobs, and automatic cluster scaling. Supports PyTorch, TensorFlow, and custom frameworks via a unified training API. Acquired by HPE (Hewlett Packard Enterprise) — integrated into HPE Machine Learning Development Environment.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Apache 2.0, HPE-backed. OIDC/SAML SSO. RBAC at workspace level. SOC2 for enterprise. Self-hosted — no external data sharing. TLS for all API communication.
⚡ Reliability
Best When
You manage a shared GPU cluster for a team of ML engineers and need fair scheduling, hyperparameter search, and experiment tracking in one integrated system.
Avoid When
You have a single researcher or small team where scheduling complexity isn't needed — MLflow + standard PyTorch training is simpler.
Use Cases
- • Maximize GPU cluster utilization across multiple researchers with intelligent job scheduling, preemption, and resource sharing
- • Run automated hyperparameter search (Bayesian, ASHA, PBT) at scale on distributed GPU clusters with early stopping and resource recycling
- • Track ML experiments with built-in metrics, artifact storage, and model registry without a separate MLflow deployment
- • Implement distributed training (data parallelism, model parallelism) with automatic fault tolerance and checkpoint recovery
- • Schedule and manage agent ML training jobs on GPU clusters via Determined's REST API or Python SDK
Not For
- • Teams without GPU clusters — Determined's scheduling benefits require multi-GPU environments
- • Inference serving — Determined is a training platform; use KServe or TorchServe for model serving
- • Teams already using Kubeflow or MLflow — switching platforms has high migration cost unless specific Determined features are needed
Interface
Authentication
Username/password with JWT tokens. API keys for programmatic access. OIDC/SAML SSO available. RBAC at workspace and project level. Service accounts for CI/CD automation. Enterprise: fine-grained RBAC with custom roles.
Pricing
Apache 2.0 open source core. Enterprise support and features via HPE. Community edition is fully functional for most use cases.
Agent Metadata
Known Gotchas
- ⚠ Determined's training API wraps user code in Trial classes — refactoring standard PyTorch code to Trial API requires significant restructuring
- ⚠ Distributed training with Determined's multi-GPU setup uses different configuration than native PyTorch DDP — debugging distributed failures requires understanding Determined's architecture
- ⚠ Checkpoint storage requires shared filesystem or object storage configuration — without it, checkpoints may not be accessible after job completion
- ⚠ Preemptible jobs can be interrupted and resumed — training code must handle checkpoint save/restore correctly or data will be lost
- ⚠ Experiment configuration YAML has many options — incorrect resource pool names or slot configurations cause jobs to pend indefinitely
- ⚠ gRPC API (determined.api.v1) is the primary programmatic interface — REST API is a wrapper and may lag behind gRPC in features
- ⚠ Webhook payloads use Determined-specific schema — agents consuming webhooks must implement Determined-specific event parsing
