A November 2025 update to GPT-5 with adaptive reasoning that spends thinking tokens only when a task needs them.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. GPT-5.1 is about 1.3x cheaper per blended million tokens (3:1 input:output mix). GPT-5.1 also takes 400K of context versus 262K for Command A. And Command A is open-weights (CC-BY-NC 4.0), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
Specs & pricing
| Command A | GPT-5.1 | |
|---|---|---|
| modhub Index | — | 59.6 |
| Input price / 1M | $2.5 | $1.25 |
| Output price / 1M | $10 | $10 |
| Context window | 262K | 400K |
| Max output | 8K | 128K |
| Open weights | yes (CC-BY-NC 4.0) | no |
| Reasoning model | no | yes |
| Multimodal input | text | text, image |
| Knowledge cutoff | Jun 2024 | Sep 2024 |
| Released | Mar 2025 | Nov 2025 |
| Example monthly cost* | $40.00 | $27.50 |
* 10M input + 1.5M output tokens per month at list prices, no caching. Green = better value on that row.
Frequently asked questions
- Which is better, Command A or GPT-5.1?
- These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. GPT-5.1 is about 1.3x cheaper per blended million tokens (3:1 input:output mix). GPT-5.1 also takes 400K of context versus 262K for Command A. And Command A is open-weights (CC-BY-NC 4.0), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
- Which is cheaper, Command A or GPT-5.1?
- Command A costs $2.5/$10 per million input/output tokens, while GPT-5.1 costs $1.25/$10. For a typical workload of 10M input and 1.5M output tokens per month, that's $40.00 versus $27.50.
