The per-token price never tells the full story. A typical task (1K input + 500 output tokens) on GPT-6 Sol costs about $0.0070, roughly $7.00 per 1,000 runs. But if it needs 3x the tokens of a cheaper model to match quality on YOUR task, the economics flip. The only way to know is to benchmark it on your actual workload.

Prompts >272K tokens priced at 2x input and cache rates, 1.5x output. Cache writes at 1.25x uncached input rate ($2.50/MTok). Batch and Flex at 50% of Standard. Fast mode at 2x. Regional processing +10%.

What that means in practice

1x One typical task (1K input + 500 output tokens): $0.0070
1K 1,000 runs of that task: $7.00
💡 Real cost depends on how verbose the model is on YOUR prompts. Benchmark to measure actual tokens, not estimates.
