Why high: an exact fingerprint shared with 1 model that declares the same family, without a second signal of a different kind yet.
Cohere: Command A is Cohere's model, and its measured tokenizer sits in Cohere's own signature group alongside its sibling models. No other maker's measured model shares it so far.
| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Counts every one of the 50 test strings exactly like 1 other model | tk_2729e470 |
| How its API is set up | A combination of settings no other listing in the catalogue uses | api_29f86139 |
| How much it can read and write | Reads up to 256,000 tokens at once, writes up to 8,192 | its own listing |
| Who served our requests | Cohere | we measured it, 5 October 2026 |
| Measured twice | The 5 October 2026 reading agreed with the 3 September 2026 reading on every one of the 50 strings clean in both: the tokenizer behind this name held. | 50/50 agree |

We sent Cohere: Command A fifty short pieces of text and recorded what each one cost it in tokens. The bars below are those costs. Two models built on the same tokenizer produce the same bars; a model built on a different one produces a different set, which is what makes this a fingerprint.
Overhead subtracted: 0 prompt tokens.
Command A is an open-weights 111B parameter model with a 256k context window focused on delivering great performance across agentic, multilingual, and coding use cases. Compared to other leading proprietary...
