These examples use the 2026-10-10 input and output prices. Cache discounts, provider surcharges and tool fees are excluded.
| Workload | Input | Output | Estimated cost |
|---|---|---|---|
| Quick test | 20,000 | 5,000 | $0.450 |
| Product chat month | 500,000 | 125,000 | $11.25 |
| Document batch | 5,000,000 | 1,000,000 | $100.00 |
Strengths
- ✓ OpenAI's flagship row: 1.05M-token context at $10 / $50 per million
- ✓ Positioned for long-horizon analysis, software engineering, research and scientific work
- ✓ Text, image and file input with a 128K output ceiling
Limitations
- ! Twenty-five times the output price of GPT-6.1 Sol in the same series — this is the row you use when the answer matters more than the invoice
- ! Text output only
- ! The catalogue carries a half-price `:batch` twin of this model which this hub does not track
