What GPT-6 Astra costs in practice

Take a typical request with 2,000 input tokens and 400 output tokens. On GPT-6 Astra:

1,000 requests cost $40.00 at standard prices.
1 million requests a month cost $40,000.
If half of each prompt is read from cache, 1,000 requests cost $31.00.
On the Batch API, with the same caching, they cost $15.50.

How to pay less for GPT-6 Astra

Cached input costs $1.00 instead of $10.00: keep system prompts, tools and documents at the start of the prompt so they cache.
Batch halves the price of work no one is waiting on.
Model choice: test cheaper GPT-6 models on the requests that don't need this one.

apicuts switches these on for you, routes each request to the lowest-cost route that passes your quality checks, and guarantees at least 20% lower cost after our fee. See pricing.
