**Short answer.** Providers price input and output tokens separately per million, with output several times more expensive than input, and discounts for cached input and batch processing. Prices change every few months; treat any table as a snapshot and check the provider's pricing page before estimating.

## What to compare (fill in current numbers)

| Provider | Model tier | Input $/M | Output $/M | Cached input | Batch discount |
| --- | --- | --- | --- | --- | --- |
| Anthropic | Frontier / mid / small | | | Yes | Yes |
| OpenAI | Frontier / mid / small | | | Yes | Yes |
| Google | Frontier / mid / small | | | Yes | Yes |
| Open models (hosted) | Various | | | Varies | Varies |

Record the date next to every number you add; this page is meant to be kept current by whoever looks it up next.

## Rules of thumb

- Output tokens usually cost 3 to 5 times input tokens.
- Prompt caching typically cuts cached-input cost by 75 to 90%; batch APIs cut both by about half at the cost of latency.
- Small models are often 10 to 30 times cheaper than frontier models and enough for classification and extraction.
