Will Agencies Bring Their Own Algorithms to Media Buying?
In an interview with ADZINE, César Masumbuku, Senior Advertiser Solutions at PubMatic, discusses the IAB Tech Lab's Agentic Real Time Framework (ARTF), which standardizes how buyer logic is deployed and executed in real-time ad auctions. ARTF allows models to be containerized and run directly within a host platform's infrastructure, such as an SSP or DSP, without external calls that waste milliseconds. This enables agencies to bring their own algorithms into the auction, but the host remains the gatekeeper, deciding which data is shared and which changes are accepted. Masumbuku explains that while results may vary across hosts, the core decision framework remains portable. He also introduces PubMatic's Decision Fabric, a containerization layer built on Agentic OS that executes partner decision models natively within the programmatic supply path, currently used for curation and traffic shaping. The framework aims to give agencies more choice and control over their media buying logic while leveraging platform infrastructure and signals.
- ARTF (Agentic Real Time Framework) is an IAB Tech Lab standard, version 1.0 completed in August 2026.
- ARTF allows buyer models to be containerized and run within host platforms like SSPs, exchanges, or DSPs.
- PubMatic offers Decision Fabric, a containerization layer on Agentic OS for running partner decision models.
