Azure OpenAI Pricing 2026:
GPT-5.4 Family & PTU Enterprise Costs
Azure OpenAI Service pricing for 2026 — GPT-5.4 family token pricing, Provisioned Throughput Units (PTU), and how Azure compares to OpenAI direct. Enterprise AI cost guide with compliance and data residency considerations. Last verified: 2026-04-01.
Azure OpenAI Pay-As-You-Go Pricing 2026
Azure OpenAI token pricing matches OpenAI's direct API pricing for the GPT-5.4 family:
| Model | Input / 1M tokens | Output / 1M tokens | Context |
|---|---|---|---|
| GPT-5.4 | $2.50 | $15.00 | 1M tokens |
| GPT-5.4 mini | $0.75 | $4.50 | 128K tokens |
| GPT-5.4 nano | $0.20 | $1.25 | 128K tokens |
| GPT-4o (legacy) | $2.50 | $10.00 | 128K tokens |
| GPT-4o mini (legacy) | $0.15 | $0.60 | 128K tokens |
| text-embedding-3-large | $0.13 | N/A | N/A |
| Whisper (speech-to-text) | $0.006/min | N/A | N/A |
For new projects, use the GPT-5.4 family. GPT-4o and GPT-4o mini remain available for existing integrations.
Azure Provisioned Throughput Units (PTU)
For high-volume, latency-sensitive workloads, Azure offers Provisioned Throughput Units — reserved capacity billed hourly or monthly:
| PTU Model | Approx. monthly cost/PTU | Throughput per PTU | Best for |
|---|---|---|---|
| GPT-5.4 PTU | ~$2,500/PTU/month | ~100K tokens/min | Enterprise, >5M tokens/day |
| GPT-5.4 mini PTU | ~$500/PTU/month | ~500K tokens/min | High-volume production, consistent latency |
| GPT-5.4 nano PTU | ~$150/PTU/month | ~2M tokens/min | Very high-volume simple tasks |
PTU break-even: If you're spending >$2,500/month on GPT-5.4 pay-as-you-go AND need guaranteed low latency, PTU is worth evaluating. Below this threshold, pay-as-you-go is cheaper and more flexible.
Azure OpenAI vs OpenAI Direct: Which to Choose?
| Factor | Azure OpenAI | OpenAI API Direct |
|---|---|---|
| Token pricing | Identical to OpenAI direct | Identical to Azure |
| Data residency | EU, US, Asia regions | US-based servers |
| GDPR / HIPAA compliance | Full enterprise compliance | Enterprise plan required |
| SLA guarantee | 99.9% uptime SLA | Best effort |
| Private networking (VNet) | VNet integration | Not available |
| Model availability | Slight lag behind OpenAI | Latest models first |
| Azure customers | One bill, Azure credits apply | Separate billing |
Hidden Costs in Azure OpenAI
- Egress costs: Transferring data out of Azure regions incurs standard Azure egress charges ($0.05–$0.09/GB)
- Azure API Management: If using APIM as a gateway, adds $0.035/10K calls
- Content Safety: Azure Content Safety filtering adds ~$1–3/1K transactions if enabled
- Storage for fine-tuning: Fine-tuned models incur storage costs ($0.023/GB/month)
Cost Example: Enterprise Chatbot (500K conversations/month)
- Average conversation: 800 tokens in + 500 tokens out = 1,300 tokens
- Total: 400M input + 250M output tokens
- GPT-5.4: $1,000 + $3,750 = $4,750/month
- GPT-5.4 mini: $300 + $1,125 = $1,425/month
- GPT-5.4 nano: $80 + $313 = $393/month
- Model selection saves $4,357/month choosing nano over GPT-5.4
