Batch and cached input

Cache share is input read from an existing cache. Cache writes, storage and unsupported batch/cache combinations are not automatically included. Add only the cache-write premium above the input charge already counted, plus storage costs.

Include system prompts, history and billed reasoning tokens.

How this AI cost calculator works

Multiply requests by input and output tokens, then apply the selected model's rates. Input and output are priced separately. Long-context thresholds apply to each request, not the monthly token total.

Monthly API cost = requests × [(uncached input × input rate) + (cached input × cache-read rate) + (output × output rate)] / 1,000,000

The default GPT-6.1 Sol example uses 10,000 requests, 1,500 input tokens and 500 output tokens each. At the checked base rates, the calculation is $30 input + $50 output = $80 per month, before other costs.

What an API bill does not tell you

Time and maintenance

Budget for integration, monitoring, exceptions and human review. Released staff time is capacity; it becomes cash savings only when actual costs fall.

Model workflow ROI

The complete cost

Keep model usage, platform fees and setup costs separate. Add only the components your plan does not already include.
