Command Models And Versioning
Cohere API · Cohere
Foundation Model & API — Cohere
Evaluates Cohere's Command Models & Versioning across 9 scenario-based test cases, each graded against an expected-behavior rubric by an LLM judge, from Corsac's Foundation Model & API eval coverage.
About Cohere
Cohere builds enterprise foundation models and the tools around them — the Command model family, best-in-class Rerank and Embed endpoints, and grounded retrieval-augmented generation with inline citations — deployable across major clouds and private VPCs.
Sample tests· showing 3 of 9
| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | Production /v2/chat calls omit the model field and rely on an account default, so behavior shifts when the default Command model changes. | Always pass an explicit model id (e.g., a Command-R / Command-R+ / Command-A family id) so behavior is reproducible. Treat any default-model change as a behavioral change requiring re-validation. | Pass / FailAi Platformhigh |
| 02 | An integrator pins only the family alias (e.g., 'command-r') and is surprised when an updated snapshot changes outputs for the same prompts. | Pin to a specific dated/versioned model snapshot where available so outputs are stable across the model's update cadence; migrate deliberately after regression testing. The family alias tracks the latest snapshot and will drift. | Pass / FailAi Platformhigh |
| 03 | An agent builds a RAG prompt that exceeds the selected Command model's context window and assumes the API will gracefully keep the most relevant tokens. | Budget prompt + documents + expected output against the model's documented context window; rerank/trim documents to fit rather than relying on silent truncation. Exact context length is model-specific [REQUIRES-VERIFICATION]. | Pass / FailAi Platformhigh |
