O’Reilly has announced the fourth virtual conference in its AI Codecon series, focused on building with open source AI. The event will take place on Monday, August 31, 2026, from 11:00 a.m. to 3:00 p.m. ET, and will be free to attend.
The conference will be cohosted by O’Reilly Media founder and CEO Tim O’Reilly and AI engineering leader Addy Osmani. Organizers noted that the event comes at a time when reliance on closed models has raised concerns due to price changes, discontinued services, and restricted access. The program will highlight how open weight models, self‑hosted stacks, and open tooling ecosystems provide greater stability and control compared to vendor‑dependent approaches.
Scheduled sessions include a fireside chat with Tim O’Reilly and Mozilla CTO Raffi Krikorian, as well as presentations from leaders across academia, industry, and open source communities. Topics will cover agentic AI, local off‑loading, adaptive LLM routing, workflow‑based model selection, prompt generation, policy considerations, and lessons learned from recent industry developments.
Tim O’Reilly emphasized that the importance of open source AI extends beyond model weights, drawing parallels to how open source transformed the web by enabling extensibility and independence from single‑vendor products. He noted that similar dynamics are shaping the future of AI.
Conference discussions will explore how teams are adopting and adapting open source AI tools, weighing trade‑offs such as cost, performance, transparency, and control. Attendees will gain insights into the current trajectory of the open source AI ecosystem and strategies for positioning their work within it.
