Open-source development is transforming AI research, but enterprise adoption remains limited, with only 13% of AI workloads running on open-source models despite over 75% of organizations intending to expand their use. AI21 Labs and Together AI have partnered to address this gap by integrating AI21 Maestro, an orchestration system for building multi-step AI agents, with Together AI’s open-source model platform, including access to the Jamba model family. This collaboration offers enterprises a streamlined method to evaluate and operationalize diverse models without altering existing workflows, ensuring transparency and control alongside cost and performance optimization. As generative AI moves into core business operations, this integration provides enterprises with the tools to inspect, govern, and adapt AI systems confidently, combining the flexibility and efficiency of open-source models with the reliability required for mission-critical environments.
