Break-Even Analysis

Understanding when Bud Foundry becomes more cost-effective

Cost Comparison by Token Volume

Daily Tokens Azure AI Foundry Bud Foundry Savings Recommendation
5M $1,435 $1,898 -32% Use Azure
10M (break-even) $2,870 $1,898 34% Either viable
25M $7,175 $1,898 74% Use Bud
50M $14,350 $2,190 85% Use Bud
100M $28,700 $3,796 87% Use Bud
200M $57,400 $7,286 87% Use Bud

Why Break-Even is ~10M Tokens/Day

Azure AI Foundry

  • Fixed Monthly Costs: ~$0 (pay-per-use)
  • Variable Costs: $2.87 per 1M tokens (GPT-4o avg)

Bud Foundry

  • Fixed Monthly Costs: $1,898 (1x A100 + license)
  • Variable Costs: ~$0 (owned compute)

Break-even: $1,898 ÷ $2.87/1M = ~661M tokens/month = ~22M tokens/day (conservative estimate: ~10M/day accounting for overhead)

When to Use Bud Foundry

Key decision criteria for your enterprise

High Token Volume

Token volume exceeds 10M/day consistently — significant savings begin immediately.

Quality Requirements Met

GPT OSS-20B quality meets your requirements (matches o1-mini benchmarks).

Voice AI Workloads

STT/TTS costs dominate your Azure bills — Whisper on GPU = $0 marginal cost.

Multi-Model Deployment

FCSP enables efficient GPU utilization — run LLM + STT + TTS + embeddings on same GPU.

Cost Predictability

Fixed compute costs vs variable API costs — essential for enterprise budgeting.

Data Sovereignty

On-premises requirements or data sovereignty needs — full control over your AI stack.

Summary

✓ 90% savings on Enterprise RAG: $28,701/mo → $2,782/mo
✓ 76% savings on Voice Agents: $18,850/mo → $4,438/mo
✓ Break-even at ~10M tokens/day — above this, Bud wins decisively
✓ GPT OSS-20B matches o1-mini — no quality compromise
✓ FCSP enables LLM + STT + TTS + embeddings on 1-2 GPUs
✓ 3-year savings: $518K-$935K depending on use case
