Key Research Findings

✅ Major Discoveries

  • Only 3 providers offer real always-free compute worldwide
  • Oracle Cloud specs rival paid enterprise plans from other providers
  • Chinese cloud providers offer no meaningful always-free options
  • European providers focus on paid excellence, no free tiers

⚠️ Important Limitations

  • Oracle account risk: Suspension reports exist but affect minority
  • Technical complexity: Self-hosted options require DevOps knowledge
  • Resource constraints: Most free tiers insufficient for serious AI work
  • Geographic restrictions: Some providers limited to specific regions

🔍 Surprising Insights

  • Oracle 24GB RAM vs Google 1GB RAM shows massive gap in free offerings
  • Trial credits disappear but always-free resources continue indefinitely
  • ARM processors (Oracle) often outperform x86 for AI inference
  • Network egress can be expensive - Oracle’s 10TB free is generous

Final Recommendations

For €0 Budget (Always Free)

  • Oracle Cloud - Only viable option for serious AI systems (24GB RAM)
  • Google Cloud - Basic AI services and APIs only (1GB RAM)
  • IBM Cloud - Watson AI APIs without compute infrastructure

For €10 Budget (Paid Options)

  • Oracle Always Free + saved budget - Best overall value
  • Hetzner + Coolify - Reliable paid option within budget
  • Scaleway - European alternative, slightly over budget

For AI Development Strategy

  • Start with Oracle Cloud - Experiment with large models for free
  • Use trial credits from multiple providers for additional resources
  • Plan migration path to paid services if scaling beyond free limits

Conclusion

Oracle Cloud Always Free tier is unmatched in the cloud industry for AI development. No other provider offers 24GB RAM permanently free, making it the only realistic option for serious AI experimentation without budget constraints.

Key takeaway: For AI systems on cloud with €10 budget constraint, Oracle Cloud’s always-free tier provides enterprise-grade resources at €0, leaving your entire budget available for other tools, data, or paid services when needed.

Risk mitigation: While account suspension risk exists, the value proposition is extraordinary. Keep trial accounts with Google Cloud and Azure as backup options, and maintain good practices to minimize Oracle account risks.

Bottom line: Start with Oracle Cloud for AI development, experiment freely with large models, and upgrade to paid services only when scaling beyond the generous always-free limits.
