Audited feedback from ML engineers running active workloads on Vast.ai.
Unbeatable spot pricing for overnight LLM pretraining and batch runs
Verified: Qwen 2.5 Batch Fine-Tuning“You simply cannot beat $0.20/hr for an RTX 4090. As long as you write resilient checkpointing to Cloudflare R2 to handle occasional spot host interruptions, Vast.ai is the highest ROI platform on earth.”

Amazing cost savings, just make sure to filter for verified hosts with >99% reliability
Verified: SDXL & FLUX Prototype“Renting 3090 instances at $0.14/hr let me bootstrap my SaaS for under $100/mo. Just use the filter to pick hosts with high bandwidth scores.”
