GPT cache and batch pricing
How caching and batch processing affect your GPT API costs.
Cache read discount
When a prompt prefix is already cached, the provider charges a reduced rate for those tokens. GPT cache read discounts range from 0% to 95% off the standard input rate, depending on the model.
Cache write cost
Cache write pricing varies across GPT models. Some charge a surcharge on the first cache write while others charge standard input rates. Check the table above for per-model details.
Batch discount
All GPT models offer a 50% batch discount. Batch requests are processed asynchronously and cost 50% of the standard rate.
GPT long-context pricing
Some GPT models apply higher rates once the total prompt exceeds a threshold. Both input and output tokens may be re-priced for the entire request.
| Model | Threshold | Input multiplier | Output multiplier |
|---|---|---|---|
| GPT 6 Luna | 272.001K tokens | 2x | 1.5x |
| GPT 5.6 Luna | 272.001K tokens | 2x | 1.5x |
| GPT 5.6 Terra | 272.001K tokens | 2x | 1.5x |

| GPT 5.4 | 272.001K tokens | 2x | 1.5x |
| GPT 5.6 Sol | 272.001K tokens | 2x | 1.5x |
| GPT 5.5 | 272.001K tokens | 2x | 1.5x |
| GPT 6 Astra | 272.001K tokens | 2x | 1.5x |

GPT API pricing FAQ
How much does the GPT API cost?
GPT API pricing starts at $0.05/MTok for input and $0.40/MTok for output. Prices vary by model tier: flagship models cost more but deliver higher quality, while fast/budget models are significantly cheaper for high-volume workloads.
Does GPT offer batch discounts?
Yes. GPT supports batch processing, which sends requests asynchronously at a reduced rate. The batch discount is 50% off standard pricing across all GPT models.
What is the GPT cache read discount?
GPT cache read discounts vary by model, ranging from 0% to 95% off the standard input rate.
How many GPT models are available?
There are currently 38 GPT models available through the API, spanning 3 tiers: Fast / Budget, Mid-tier, Flagship.
Is there a free tier for the GPT API?
GPT API pricing is pay-per-use based on token consumption. There is no permanent free tier, but new accounts typically receive introductory credits. Tokeven helps you track exactly what you spend so nothing is wasted.
Does GPT charge more for long context?
Yes. Some GPT models apply a long-context surcharge when the total prompt exceeds a token threshold. Both input and output rates increase for the entire request. Check the long-context pricing table above for exact thresholds and multipliers per model.
