Pros
  • Substantially cheaper H100/A100/B200 hours than AWS, GCP or Azure
  • Per-minute billing with no egress fees
  • Pre-installed Lambda Stack means instances are training-ready in minutes
  • Offers both single on-demand GPUs and full multi-thousand-GPU clusters
  • SOC 2 Type II with single-tenant hardware isolation on clusters
  • Easiest fine-tuning UX
  • Vision FT now supported
  • Works inside the OpenAI ecosystem
  • Same infra/SLA as base models
Cons
  • Popular GPUs (H100, B200) are frequently sold out
  • No managed fine-tuning-as-a-service API - you run your own training stack
  • Fewer managed services and regions than AWS/GCP/Azure
  • Pricier than open-model FT
  • No weights export
