Command A vs GPT-5.1

Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.

Command A

Cohere · Mar 2025

Cohere's enterprise RAG specialist — 111B dense, two-GPU deployable, with downloadable weights for private deployments.

GPT-5.1

OpenAI · Nov 2025

59.6

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.

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.
Which model is better for coding, Command A or GPT-5.1?
We don't yet track SWE-bench Verified results for both models; check their individual pages for coding-related scores.
