Provider comparison
Lambda vs Vast.ai
Lambda
Lambda Labs is purpose-built for ML teams - simple, transparent per-hour rates on H100, H200, B200, and GB200 instances with zero hidden fees. Known for responsive support and direct hardware access, it is a top choice for training runs that need predictable pricing without cloud-platform complexity.
Vast.ai
Vast.ai is a decentralized GPU marketplace where host operators list idle accelerators at market-driven prices - often the lowest spot rates anywhere. The trade-off is variable reliability, no compliance certs, and community-grade support; ideal for cost-sensitive experimentation, fine-tuning, and batch inference where occasional interruption is acceptable.
