Tokens for a fixed budget
Tokens GPT-5.4 mini can process for a set budget — send-only, reply-only, and a 70/30 mix.
| Budget | Input tokens | Output tokens | Mixed tokens (70/30) |
|---|---|---|---|
| $0.01 | 13,333 | 2,222 | 5,333 |
| $0.1 | 133,333 | 22,222 | 53,333 |

| $1.00 | 1.33M | 222,222 | 533,333 |
| $5.00 | 6.67M | 1.11M | 2.67M |
| $10.00 | 13.3M | 2.22M | 5.33M |

At these rates
- A workload with 70% input and 30% output costs $1.875 per 1 million total tokens and $187.50 per 100 million.
- At the same token count, output costs 6 times the input rate. Response length therefore deserves its own budget limit.
- Filling the 400,000-token context window with input alone would cost about $0.3, before any output.
- Cached input is $0.075 per million, 90% below standard input when the workload meets the provider’s cache rules.
These figures use public list prices. Cache eligibility, batch or priority modes, long-context surcharges, discounts, and regional billing can change the invoice.
