At these rates
- A workload with 70% input and 30% output costs $0.1467 per 1 million total tokens and $14.67 per 100 million.
- At the same token count, output costs 8.53 times the input rate. Response length therefore deserves its own budget limit.
- Filling the 128,000-token context window with input alone would cost about $0.00576, before any output.
