Hi Pranav Gupta

Welcome to Microsoft Q&A and Thanks for sharing the details.

You’re reading the pricing correctly the image confirms the pay‑as‑you‑go rates for Claude Opus 4‑5 on Azure AI Foundry:

• Model input: $0.005 per 1,000 tokens
• Model output: $0.025 per 1,000 tokens

Cache-related costs (optional optimizations):

Write tokens: $0.00625 per 1,000

• Hit tokens: $0.0005 per 1,000
• 1‑hour cache write: $0.01 per 1,000

That translates roughly to $5 per million input tokens and $25 per million output tokens, which matches what you mentioned.

Deployment on Azure AI Foundry

• When you deploy Claude Opus 4‑5 as a base model, there’s no extra hosting fee—you only pay for API inference calls (token usage and any optional caching).
• No separate Anthropic contract; billing flows through your Azure subscription.
• Startup credits don't apply. It is only available for enterprise and MCA-E subscriptions.
