Lambda Labs Cloud API
GPU cloud computing API providing on-demand and reserved access to NVIDIA H100, A100, and V100 GPU clusters for ML training, fine-tuning, and inference workloads.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API key auth. GPU instance provider — instances have full GPU and network access. SSH key management for instance access. SOC2 Type II. GPU instances can run arbitrary code — agent-provisioned instances require careful monitoring.
⚡ Reliability
Best When
You need dedicated GPU instances at competitive prices for ML training or long-running inference, with simple REST API management.
Avoid When
You need serverless GPU compute (use Modal), multi-cloud availability, or enterprise support.
Use Cases
- • Launching GPU instances for ML model training via REST API from agent pipelines
- • Programmatically managing GPU cluster lifecycle (start, stop, terminate)
- • Automated provisioning of GPU clusters for batch fine-tuning jobs
- • Cost-optimized GPU compute as an alternative to AWS/Azure for ML workloads
- • Persistent GPU instance management for long-running inference servers
Not For
- • Serverless or auto-scaling compute (Lambda Labs is always-on instance management)
- • Non-GPU CPU workloads (overpriced for CPU-only work)
- • Teams requiring enterprise SLA beyond what Lambda Labs provides
Interface
Authentication
API key via Bearer token in Authorization header. Keys have full account access. Generate in Lambda Labs dashboard. No fine-grained scopes.
Pricing
Per-hour billing for GPU instances. Significantly cheaper than AWS/Azure/GCP for comparable GPU hardware. Reserved instances offer further discounts. On-demand availability varies.
Agent Metadata
Known Gotchas
- ⚠ GPU availability is limited and on-demand instances may not be available — always handle 'insufficient capacity' errors
- ⚠ Instances are not terminated when SSH session ends — must explicitly call DELETE to avoid ongoing charges
- ⚠ SSH keys must be pre-registered in the Lambda Labs dashboard before launching instances
- ⚠ No auto-scaling or managed containers — must handle all instance lifecycle management manually
- ⚠ On-demand availability varies significantly by GPU type and region — plan with reserved instances for critical workloads
- ⚠ Storage is ephemeral on instances — persistent storage must use filesystems or external object storage
