Cohere
Enterprise-focused model provider offering Command generation models plus Embed and Rerank models for search and retrieval-augmented generation, with cloud, VPC, and on-premises deployment.
Cohere is a model provider that builds foundation models for enterprises that need to keep data inside their own boundaries. It offers three product lines: Command models for generation, Embed models for turning text and images into vectors, and Rerank models that reorder search results by relevance. Cohere’s positioning centres on search and retrieval-augmented generation , plus deployment flexibility for companies that cannot send data to a public API.
The company packages these models under North, an enterprise AI platform for workplace productivity, and Compass, a search and discovery system. The underlying models are also available directly through Cohere’s API and through major cloud marketplaces.
Where Cohere sits in the stack
Cohere spans two roles in a typical AI application: it supplies the generation model that writes answers, and it supplies the retrieval models that decide which documents feed those answers.
How to access it and how it fits
You can reach Cohere’s models four ways: the hosted Cohere API, a private deployment inside your own virtual private cloud (VPC), a fully on-premises install, and cloud marketplaces. Cohere lists availability across Amazon Bedrock, Amazon SageMaker, Microsoft Azure, and Oracle Generative AI Service. In September 2025 the company added Model Vault, a dedicated inference platform that runs Command, Embed, and Rerank inside isolated VPC or on-premises environments.
The models divide by job:
The Command line covers a range of needs. Command A (command-a-03-2025) targets tool use, agents, and RAG. Command A+ (command-a-plus-05-2026) is a mixture-of-experts model with vision and reasoning. Command R7B is a small, fast model for RAG and tool use. Context lengths across the Command family run from 8K to 256K tokens, and the multilingual variants cover dozens of languages.
Compared to other model providers
Cohere is narrower than the general-purpose labs but deeper on retrieval. Here is how it lines up.
| Cohere | Anthropic | Mistral AI | AI21 Labs | |
|---|---|---|---|---|
| Core focus | Enterprise RAG and search | Frontier reasoning models | Open-weight and hosted models | Enterprise long-context models |
| Retrieval models | Embed and Rerank | None first-party | Embed model | None first-party |
| Deployment | API, VPC, on-prem, clouds | API and cloud marketplaces | API, cloud, some open weights | API and cloud |
| Best for | Regulated RAG at scale | Complex reasoning tasks | Cost-flexible general use | Long-document tasks |

When not to use it
Cohere is a focused choice, not a default. Consider alternatives when:
- You want the top reasoning benchmarks. The largest frontier chat models from other labs often lead on public reasoning leaderboards. Cohere optimises for enterprise retrieval and deployment, not headline scores.
- You need a large consumer ecosystem. Cohere sells to enterprises. If you want a broad third-party plugin and app ecosystem, other providers offer more.
- You only need a chatbot. If you are not doing search or RAG, the Embed and Rerank strengths that differentiate Cohere go unused, and a simpler single-model provider may cost less.
- You want fully open weights to self-modify. Cohere ships private deployments, but its frontier models are not permissively open in the way some open-weight families are.
