Frontier LLM list price, plus 30% to Bench.
Here are the three flagship seats. Rates are dollars per million tokens.
| Model | Input: list → you pay | Output: list → you pay |
|---|---|---|
| Grok 4.6 | $2.00 → $2.60 | $6.00 → $7.80 |
| Claude Opus 5 | $5.00 → $6.50 | $25.00 → $32.50 |
| GPT-5.6 Sol promo | $4.00 → $5.20 | $20.00 → $26.00 |
GPT-5.6 Sol uses its promo rate through 2026-11-21.
What changes the bill
Input tokens are what the model reads. Output tokens are what it writes. More of either means a larger charge. The model you choose matters too.
When a model runs, what you pay comes out of Fuel. The rate card and calculator show the rest of the lineup and let you estimate a run before it starts.
Why 30% to Bench?
Bench pays the model providers first. Once the tokens are burned, their bill is due.
If your payment fails after that, Bench still pays. Bench carries the loss.
The 30% covers that risk. What's left is a thin keep.
Rates checked 2026-08-29. Model providers can change their prices, so this post is dated on purpose.
