Zeta Global announced a strategic collaboration with Fireworks to develop Athena Inference Models, a collection of specialized open-weight models powering specific AthenaOS use cases, designed to help customers generate insights faster, improve efficiency and scale specialized AI across the enterprise.
Developed in collaboration with Fireworks and powered by NVIDIA Nemotron open models, Athena Inference Models work across enterprise data and Zeta’s proprietary intelligence to connect changes in customer demand and what it means for the business. Athena Inference Models will work alongside Zeta’s existing predictive models to help AthenaOS deliver more relevant intelligence and better recommendations, with each enterprise’s objectives guiding the action..
“The Athena Inference Models are critical in how we bring our intelligent AI infrastructure to life and advance data and AI sovereignty,” said David A. Steinberg, Co-Founder, Chairman and CEO of Zeta Global. “Models are increasingly available, but context is owned. Athena Inference Models help organizations harness their most strategic assets securely and effectively, connecting their data and context to AI in a way that improves how decisions are made and work gets done. That is the advantage we are building for our customers.”
Built on NVIDIA Nemotron open models and fine-tuned using Fireworks infrastructure, the Athena Inference Models are designed for specialized AthenaOS tasks, including interpreting domain language and following brand voice, formatting and output requirements.
Athena Inference Models support enterprise data-control and sovereignty requirements, enabling customers to apply their first-party data in a governed environment while retaining control over how it is used. In early testing, Athena Inference Models achieved accuracy on par with state-of-the-art industry leading models. Zeta expects Athena Inference Models to help customers unlock faster insights, greater efficiency, and enterprise-wide scalability.
“General-purpose models provide the foundation, but open models unlock the proprietary data and specialization that drive the next leap in performance,” said Nate Yohannes, President of Data & AI Lab and Global Head of Research and Development at Zeta Global. “Athena Inference Models give AthenaOS a more efficient way to understand enterprise context, apply specialized skills and deliver more useful recommendations across the business.”
“At Fireworks, we believe enterprises require specialized intelligence because data sensitivity cannot be an afterthought,” said Benny Chen, Co-Founder at Fireworks. “By combining Zeta’s proprietary intelligence with Fireworks’ infrastructure for training, tuning, and serving open models, the Athena Inference Models are more accurate, more efficient, and tailored to Zeta’s specific business needs.”
The announcement builds on Zeta’s continued investment in AthenaOS, the enterprise intelligence operating system that dynamically builds around a user’s objective and brings intelligence into the tools and applications where work already happens.
Athena Inference Models are currently in development and will be part of the AthenaOS beta later this year.
