L40 on Vast.ai
Visit Vast.aiVast.ai provides access to the NVIDIA L40 GPU, equipped with 48GB GDDR6 VRAM on the Ada Lovelace architecture, optimized for enterprise data center workloads including AI inference, visualization, and rendering. This decentralized marketplace stands out by offering the absolute lowest rental costs—frequently under $1 per hour—through direct host competition, making high-VRAM GPUs accessible without enterprise contracts. Noteworthy for ML engineers and data scientists handling large-scale inference on models like Llama 70B or Stable Diffusion, it excels in cost-per-performance via granular filters such as DLPerf/$. Key value propositions include per-second billing, spot instances for up to 70% savings, and support for distributed experiments across global hosts. Ideal for budget-conscious teams prioritizing ROI on memory-intensive AI tasks over premium support.
Why NVIDIA L40 on Vast.ai?
Vast.ai paired with NVIDIA L40 offers unmatched cost efficiency for its 48GB VRAM and inference prowess, leveraging the decentralized marketplace to undercut traditional clouds by 50-80%. Hosts compete on price, enabling per-hour rates as low as $0.60-$1.20, with spot instances for interruptible workloads slashing costs further. Granular filters like DLPerf/$, VRAM/$, and host reliability ensure optimal selection for L40's strengths in FP8/FP16 inference and ray tracing. This combo suits short-term experiments or scale-outs, complementing L40's enterprise tier with flexible scaling, no egress fees, and Docker-based deployments for rapid PyTorch/TensorFlow setups—perfect for cost-sensitive ML teams avoiding lock-in.

Performance Notes
NVIDIA L40 on Vast.ai delivers robust Ada Lovelace performance: ~90 TFLOPS FP16, 181 TFLOPS sparse Tensor FP16, ideal for inference on 30-70B models with 48GB VRAM. Host-dependent factors include 10-100Gbps networking (adequate for most distributed jobs), NVMe SSD storage (1-20TB typical), and PCIe 4.0/NVLink for multi-GPU scaling up to 8x with near-linear efficiency in NCCL benchmarks. DLPerf scores (via Vast.ai filters) indicate reliable ML throughput, but variability exists due to host configs (CUDA 12+, driver 535+). Spot instances risk preemption; on-demand offers stability. Unknowns: exact inter-host InfiniBand prevalence—verify per listing for H100-like scaling.

Frequently Asked Questions
What is Vast.ai's billing model for NVIDIA L40?▾
Vast.ai bills per-hour for GPU instances including NVIDIA L40. Hourly billing means you pay for full hours even if your job completes mid-hour. Plan your workloads accordingly to maximize cost efficiency.
Does Vast.ai offer spot instances for NVIDIA L40?▾
Yes, Vast.ai offers spot/preemptible instances for NVIDIA L40, which can reduce costs by 50-80% compared to on-demand pricing. Spot instances are ideal for fault-tolerant workloads like batch inference, hyperparameter tuning, and training jobs with checkpointing. Note that spot instances can be interrupted when demand is high, so ensure your workflow can handle preemption gracefully.
