Token estimate helper
Useful when you know document size before you know request tokens.
Estimated total tokens
0
Estimate only. Default assumptions: 1 token ~= 0.75 English words, 1 token ~= 1.5 Chinese characters, 1 page ~= 500 English words.
How the calculator interprets inputs
- `Cache hit ratio` discounts only the cached share of input tokens.
- `Batch discount` applies only when the stored snapshot lists a batch ratio for that model.
- `Budget fit` means the maximum monthly requests you can afford with the exact request shape above.
Estimated results
Monthly cost stays sorted low to high. Added fields help answer budget fit, cache value, and request-level economics.
| Model | Monthly cost | 1k requests | Blend / 1M | Cache savings / month | Batch savings / month | Budget fit |
|---|---|---|---|---|---|---|

Official OpenAI pricing baseline manually verified against https://openai.com/api/pricing/ and https://developers.openai.com/api/docs/models/all on 2026-03-30. Stored as a bootstrap snapshot because the official pricing page may return an anti-bot challenge to server-side crawlers. Batch pricing is modeled as 50% of normal input/output pricing where OpenAI lists Batch API support.
