The Open Layer: How Open Models, Routing, and Inference Are Reshaping Agentic Engineering

  • Coding Agents & Autonomous Dev

Closed frontier models get the headlines, but the agentic revolution is being built on something more flexible and more interesting: a hybrid stack of open-weight models, intelligent routing, and high-throughput inference infrastructure. In this panel, founders building the open AI ecosystem — from fine-tuned model deployment to multi-model orchestration to optimized routing and serving — get into what "open" actually means in 2026, and where it falls short.

We'll dig into the real engineering tradeoffs: when open models win in agentic pipelines, when they don't, how routing and inference choices shape latency and cost at scale, and what it takes to build reliable agents in this open ecosystem as always-on agents become an increasingly core part of agentic engineering.

Arcee AI

Lucas Atkins serves as CTO and Head of Research at Arcee AI, where he spearheaded the proprietary training stack behind Trinity, Arcee’s family of open-weight foundation models. A veteran in machine learning, Lucas engineered next-generation text-to-speech systems for leading automotive giants such as Volkswagen, BMW, Ford, and Hyundai starting well before the current generative AI surge. He has also led training of specialized language translation systems for the UAE and partnered with AMD in 2023 and 2024 to optimize enterprise GPUs for large-scale model training. He now uses that end-to-end experience to shape Arcee’s in-house models, aiming for efficient, open source & open-weight models that set the standard for American made open intelligence.
