GPU Cloud Pricing Comparison 2026
If you're self-hosting models or running compute-intensive AI tasks:
| GPU | Provider | On-Demand $/hr | Spot $/hr | Best For |
|---|---|---|---|---|
| A100 80GB | RunPod | $1.89 | $0.99 | Llama 70B inference, fine-tuning |
| A100 80GB | Lambda Labs | $2.49 | N/A | Reliable, no spot interruption |
| A100 80GB | AWS (p4d) | $32.77 | $9.83 | Enterprise, compliance needed |
| H100 80GB | CoreWeave | $4.25 | N/A | Fastest inference, training |
| RTX 4090 24GB | RunPod | $0.74 | $0.40 | Llama 8B, 7B models, dev |
| A10 24GB | Vast.ai | $0.40 | $0.20 | Cheapest for small models |
Vector Database Pricing Comparison
| Provider | Free Tier | Paid (per month) | Vectors |
|---|---|---|---|
| pgvector (self-host) | Free (Postgres) | $0 variable | Unlimited |
| Pinecone Serverless | 100K vectors free | $0.096/1M vectors | 1M+ |
| Supabase pgvector | 500MB free | $25/month | 1M+ vectors |
| Weaviate Cloud | 14-day trial | $25+/month | Variable |
| Qdrant Cloud | 1GB cluster free | $25+/month | ~1M vectors |
Best choice for most startups: pgvector on Supabase or Neon — you get a vector database for free as part of your existing Postgres setup.
