Developers connect to Cohere's endpoints. To build enterprise search, they pass their company documents through Cohere's Embeddings API, transforming the text into vector data stored in a database. When a user queries the system, the Rerank API surfaces the most mathematically relevant internal documents. Finally, the Command model reads only those specific documents and generates a conversational answer, providing inline citations bridging the generated text directly to the source file.
Cohere API
The Cohere API is an enterprise-focused artificial intelligence platform providing access to foundational large language models. Rather than attempting to build consumer chatbots, Cohere strictly focuses on equipping businesses and developers with tools to implement Search, Retrieval-Augmented Generation (RAG), and text classification into corporate environments.
Cohere is uniquely positioned due to its specialization in multi-lingual models and its industry-leading Embeddings models. Embeddings are the mathematical representations of text that power semantic search—essentially allowing a computer to understand that "cheap hotel" and "affordable lodging" mean the same thing, even if the keywords don't match.
Its command models (like Command R+) are explicitly fine-tuned for building enterprise RAG systems, ensuring that when an AI answers a question, it cites specific internal company documents, reducing hallucinations to near zero.
Best For

Pros & Cons
Pros
- The Rerank and Embeddings models are arguably the best in the industry for semantic search
- Command models are specifically built to cite their sources, solving enterprise generation fears
- Deeply optimized for B2B data privacy
- Cloud-agnostic deployment options for security-conscious firms
Cons
- Not optimized for casual, creative, or pure conversational use cases
- Base Command models historically lagged behind GPT-4 in raw reasoning before R+
- Strictly a developer product requiring engineering infrastructure
- Less consumer brand recognition limits non-technical executive buy-in
Pricing
Cohere operates on a pay-as-you-go API model based on tokens processed. They offer distinctly separate pricing for their Generation (Command), Embeddings, and Rerank endpoints. Enterprise customers can negotiate private deployments securely inside AWS, Azure, or Oracle clouds.
How It Compares
Cohere competes with OpenAI, Anthropic, and AI21 Labs. While OpenAI and Anthropic build large-scale, generalized "everything" models, Cohere proactively targets the middle layer of enterprise infrastructure: specifically, search and RAG. Developers often use Cohere's Embeddings and Rerank APIs to handle the database search portion of an application, even if they occasionally use another model (like GPT-4) to write the final output, solidifying Cohere's unique value in the AI data pipeline.
