Command A vs GPT-5.5
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Cohere · Mar 2025
Cohere's enterprise RAG specialist — 111B dense, two-GPU deployable, with downloadable weights for private deployments.
OpenAI · Apr 2026
OpenAI's flagship reasoning model with a 1M-token context window, built for hard coding, science and long-horizon agentic work.
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. Command A is about 2.6x cheaper per blended million tokens (3:1 input:output mix). GPT-5.5 also takes 1M 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.

| Example monthly cost* | $40.00 | $95.00 |
* 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-5.5?
- These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Command A is about 2.6x cheaper per blended million tokens (3:1 input:output mix). GPT-5.5 also takes 1M 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-5.5?
- Command A costs $2.5/$10 per million input/output tokens, while GPT-5.5 costs $5/$30. For a typical workload of 10M input and 1.5M output tokens per month, that's $40.00 versus $95.00.
