Cohere debuts PromptTune: on-prem model tuning suite for design teams

AI · 6 min read

PromptTune is Cohere's new suite aimed at enterprises that need to customize language models without exposing data to public clouds. The toolkit supports low-cost fine-tuning, retrieval-augmented generation setups, and a visual prompt editor for non-technical designers.

Cohere emphasized governance features such as audit logs, token monitoring, and drift detection to catch quality regressions in deployed assistants. PromptTune's visual editor allows teams to craft chained prompts and define deterministic fallback behaviors for production assistants.

The product includes templates for common design workflows—microcopy generation, component documentation, and plugin prompts—helping design operations maintain quality under scale. Cohere will offer enterprise support and consulting to help customers integrate PromptTune into CI/CD pipelines.
