Cohere, a leading company in the AI sector, has effectively utilized Fern's open-source tool to automate the generation of its SDKs, thus enhancing its Retrieval Augmented Generation toolkit's accessibility and usability across different programming languages. Initially, Cohere faced challenges in manually maintaining SDKs for languages like TypeScript and Go, which had differing type systems and concurrency models. This manual approach resulted in inconsistent updates and frequent errors. By adopting Fern, Cohere streamlined its SDK development process, allowing for the creation of idiomatic SDKs that maintain the unique advantages of each language while ensuring consistency and reducing maintenance overhead. Fern's compatibility with the widely accepted OpenAPI spec allows Cohere to focus on crafting a centralized API specification, leaving Fern to manage the automatic generation and publication of SDKs. This shift has significantly improved the quality and reliability of Cohere's SDKs, providing users with a more seamless experience and enabling Cohere to allocate its engineering resources more efficiently.
