Lambda Labs
GPU cloud for ML researchers and AI developers - rent on-demand H100, A100, and A10 GPUs by the hour for model training, fine-tuning, and inference.
Lambda Labs is a GPU cloud provider built specifically for AI and ML workloads, offering on-demand access to H100, A100, and A10G instances without reserved instance commitments. Researchers and developers get a pre-installed stack with CUDA, cuDNN, PyTorch, and TensorFlow on every instance, eliminating hours of environment setup. Lambda also offers persistent cloud workstations for long-running ML research and a serverless inference API for hosting open-weight models like Llama 4 and Mistral. The platform is trusted by ML teams at academic institutions, AI labs, and startups who need GPU availability that consistently outperforms hyperscalers for ML-specific workloads.
Key Features
- On-demand GPU instances - H100 SXM5, A100 80GB, and A10G available by the hour with no minimum commitment
- One-click Jupyter notebooks - pre-configured ML environments with PyTorch, TensorFlow, and CUDA ready on boot
- Lambda Inference API - serverless endpoints for Llama 4, Llama 3.3, Mistral, and other open-weight models
- Persistent cloud workstations - long-running GPU workstations for continuous ML research and experimentation
- Team access controls - shared filesystems, per-user IAM, and spend tracking for ML research groups
- Pre-installed ML stack - Ubuntu instances with CUDA, cuDNN, PyTorch, TF, and Jupyter pre-configured on every boot
Use Cases
- ML researchers running GPU-intensive training jobs without maintaining on-premises hardware or reserved cloud instances
- AI startups fine-tuning open-source LLMs on proprietary datasets before deploying models to production
- Individual developers training image generation or NLP models on A10G instances at lower cost than AWS or GCP
- Research teams running hyperparameter sweeps and large-scale experiments that exceed local GPU capacity
Pros
- Better H100 availability at competitive hourly rates compared to AWS or Google Cloud for pure ML workloads
- No minimum spend or reserved instance commitment - pay only for the GPU hours actually used
- Pre-installed CUDA and ML framework stack saves hours of environment setup on every new instance launch
Cons
- No managed MLOps pipelines or experiment tracking built in - requires separate tools like W&B or MLflow
- No spot or preemptible instance pricing - costs more than preemptible options on AWS for interruptible jobs
- Limited geographic regions compared to AWS or Azure - may not satisfy data residency requirements in all markets
