Lepton AI is a platform for deploying AI models and fine-tuning LLMs. Simple API, pay-per-token pricing, and managed GPU infrastructure. Built by ex-Meta researchers.

Lepton AI offers on-demand GPU access with per-second billing, eliminating idle costs. Deploy open-source models or custom code via simple APIs. Features include automatic scaling, built-in model caching, and support for various accelerators (NVIDIA GPUs, TPUs). Differentiator: competitive per-second pricing and faster cold starts compared to traditional cloud providers.

Pros

  • Pay per second—scale from zero to thousands of requests without minimum commitments
  • Deploy models instantly with pre-optimized templates for popular LLMs
  • Reduce latency through model caching and optimized inference
  • Access multiple GPU types and generations without vendor lock-in

Cons

  • Limited regional availability compared to major cloud providers
  • Smaller ecosystem and community than established alternatives like AWS/GCP
  • Per-second billing can be expensive for sustained, long-running workloads

Best For

ML engineers and startups running inference workloads who need low-latency, cost-efficient GPU access without managing infrastructure.
