Keynote: Open Source for AI and AI for Open Source - Priya Nagpurkar, Vice President, Hybrid Cloud and AI Platforms, IBM Research

Tuesday August 11, 2026 10:15 - 10:30 KST

Grand Ballroom 2-3

Open source has been the single most powerful force democratizing AI—taking capabilities that might otherwise be confined to a handful of well-resourced labs and putting them within reach of researchers, developers, and IT operators everywhere. But the relationship runs both ways: as AI systems increasingly write and contribute code, they are reshaping the open-source ecosystem itself—straining how we manage a rising tide of machine-generated contributions and how we secure code in an era when both attackers and defenders are AI-augmented. In this keynote, I make the case for why open models and open technologies like PyTorch, vLLM, and llm-d are critical enablers for enterprises and governments seeking greater control and flexibility over their AI, and I highlight the technical innovation making this possible. I close by arguing that we have a real opportunity to turn this two-way street into a virtuous loop—building AI that accelerates and secures open source even as open source accelerates AI.

Squeezing Every Millisecond: A Practical Guide To Optimizing Time To First Token With OSS Muscle - Aman Mundra, Welzin.ai & Hrittik Roy, Platform Advocate

Tuesday August 11, 2026 11:00 - 11:30 KST

Grand Ballroom 2-3

Large language models are getting faster GPUs every year, yet users still notice the pause before the first word appears. That pause has a name: Time To First Token (TTFT). And in production LLM systems, shaving even a few hundred milliseconds from it can dramatically change how responsive an application feels.

This talk tells the story of where those milliseconds go.

We will walk through the lifecycle of a request in modern LLM serving systems and explore the practical techniques engineers use to reduce TTFT in real deployments. Using examples from open source stacks like vLLM, TensorRT-LLM, and Hugging Face TGI, we will examine four powerful optimization levers: KV cache strategies, speculative decoding, model quantization, and batching policies.

Instead of focusing only on theory, the session highlights the tradeoffs practitioners face. When does speculative decoding actually help? When does batching hurt latency? When does quantization reduce memory pressure enough to speed up the first token?

Attendees will leave with a practical playbook for diagnosing TTFT bottlenecks and choosing the right optimization strategy for their model, infrastructure, and workload.

Stop Trusting a Black Box: The Economic Case for Open, Sovereign AI - Vincent Caldeira, Red Hat

Tuesday August 11, 2026 11:40 - 12:10 KST

Grand Ballroom 2-3

As AI matures from a novelty into a strategic asset, 79% of organisations now prioritise sovereignty to mitigate vendor lock-in and secure critical data. Despite this, the market remains paralysed by a paradox: while open models have achieved performance parity with proprietary systems at a fraction of the cost, they remain massively under-utilised due to perceived friction and trust gaps.

This session dissects this market inefficiency, with insights from LF Research revealing how closed-source dominance is often driven by inertia rather than superior capability. We will explore how to operationalise true independence by rejecting "open-washing" in favour of rigorous frameworks that demand full model completeness: verifying everything from training data to weights. Join us to learn how to transition from renting black-box APIs to architecting a transparent, reproducible, and economically superior AI stack.

Science in the Agentic Era: Structured Experimentation With Ado - Alessandro Pomponio, IBM

Tuesday August 11, 2026 13:35 - 14:05 KST

Grand Ballroom 2-3

As AI agents become increasingly capable of generating code and executing complex workflows, their use in research is still limited by concerns about rigour and reproducibility. This session introduces ado, an open-source framework that brings structure to agent-driven scientific experimentation.

ado defines schemas for the core elements of a discovery process: the problem space and how to explore it. Agents iteratively propose and refine experimental campaigns as validated configurations based on these schemas, while ado handles execution. This separation of research intent from execution constrains agents to focus on the research task, reducing hallucinations and the need to write boilerplate code. Combined with a set of agent skills for formulating problems, creating and running experiments, and analysing their results, ado provides a framework for end-to-end agent-driven discovery workflows.

Whether you are an experienced researcher or new to computational experimentation, this talk presents a practical model for integrating AI agents into research workflows while keeping experimentation structured, transparent, and reproducible.

The Era of Vibe Coding: Why High-Skill Engineers Are More Critical Than Ever - Yongjin Lee, Songnae High-school

Tuesday August 11, 2026 14:15 - 14:45 KST

Grand Ballroom 2-3

"Let’s be real: My AI has dementia."
"Vibe-coding in real: Me and My AI is stupid"
Welcome to the "Vibe Coding" era, where anyone can prompt their way to complex code. But as a 17-year-old developer who "bullied" LLMs to build a custom Linux Based OS (MaruxOS) from scratch, I’ve seen the ugly truth: AI is a brilliant assistant, but a chronic liar with a 5-minute memory.
In this session, I expose the messy reality of AI-native development. I’ll share how I battled "Contextual Dementia"—where AI forgets my ARM64 architecture mid-patch—and survived "Mindless Yes-Clicking Syndrome," where a single trusted prompt almost nuked my entire glibc.
Key Takeaways:
The Hallucination Hunter: Sniffing out AI’s "confident bullshit."
The Dementia Doctor: Managing AI’s memory loss to maintain architectural integrity.
The Final Decider: Moving beyond the "Yes-Clicking" trap to take true technical ownership.
AI might be writing the code, but only a real engineer can stop it from burning the house down.

Open Source AI Agents on User-Owned Infra: K3s, MCP, and GPU Sharing in Practice - Miley Fu, OlaresOS

Tuesday August 11, 2026 14:55 - 15:25 KST

Grand Ballroom 2-3

Most open-source AI demos stop at a chatbot, but real users want agents that can work with private files, call tools, and run close to their important data without sending everything to the public cloud.

This talk shows a practical reference architecture for private agent workflows on a single-node K3s-based personal cloud, including local model serving, private knowledge bases, app sandboxing, secure remote access, and multiple GPU allocation modes for competing AI workloads.

Using an open-source personal cloud OS as a case study, I will share what works, what breaks, and which design choices matter when you try to make local AI usable by developers, creators, and small teams rather than just homelab experts.

MCP Adoption and Why OSPO Skills Matter - Ana Jiménez Santamaría, Linux Foundation (TODO Group and PyTorch Foundation)

Tuesday August 11, 2026 15:55 - 16:25 KST

Grand Ballroom 2-3

As organizations explore the Model Context Protocol (MCP), many of the early conversations naturally happen around AI tooling, integrations, and experimentation. At the same time, MCP may also raise questions that are familiar to Open Source Program Offices (OSPOs) and related teams or professionals with open source management experience, including governance, contribution strategy, standards engagement, and cross-functional coordination

This talk reflects on what organizations might gain by bringing those perspectives into MCP discussions earlier, as well as into their broader Agentic AI strategy. Rather than treating MCP only as a technical AI topic, the session will explore it as an area where open source process knowledge may also add value. Attendees will leave with ideas for how OSPOs can contribute to MCP adoption in practical, collaborative, and organization-aware ways

Benchmarking Beyond OpenSearch: Multi-Engine Vector Search Performance With OSB - Mike Oviedo, AWS

Tuesday August 11, 2026 16:35 - 17:05 KST

Grand Ballroom 2-3

As vector search becomes foundational to AI workloads, teams need reliable ways to evaluate engine performance before committing to one. We extended OpenSearch Benchmark (OSB) to support Milvus and Vespa alongside OpenSearch, making it possible to compare throughput, latency, and recall across engines using the same datasets and query patterns.

In this talk, we'll walk through how OSB's new engine-as-module architecture lets you benchmark any search engine with a single CLI command. We'll show how customizable workload parameters control everything from HNSW graph construction to bulk ingestion strategies, and demonstrate how to visualize comparative results in OpenSearch Dashboards, turning raw benchmark data into actionable performance insights.

Whether you're evaluating engines for a new project or optimizing an existing deployment, you'll leave with practical knowledge of how to run your own benchmarks and how to extend OSB to support additional engines by implementing five functions.

Personalisation and Specialisation of Search With OpenSearch Agentic Search - Cedric Pelvet & Aswath Srinivasan, AWS

Tuesday August 11, 2026 17:15 - 17:45 KST

Grand Ballroom 2-3

Agentic search lets you ask in Natural Language and have OpenSearch plan and execute retrieval. The Query Planner re-writes Natural Language to OpenSearch DSL using SOTA LLMs. This works amazingly well but not without important limitations:

1/ The biggest factor is added latency for remote inference. eCommerce Search demands sub-100ms response times. Even the best results when slow lead to search abandonment.
2/ We'll demo overcoming latency by hosting SLMs locally within OpenSearch nodes using vLLM/Ollama. This is faster & cheaper, but SLMs suffer quality decline in query re-writes. We'll explore fine-tuning with domain-specific data—proving fine-tuned SLMs beat SOTA LLMs.
3/ Relevance remains generic even with Agentic Search. We'll show how to improve it using user and business contexts with hybrid search and reranking.

This hands-on talk covers:
1/ Search Latency with Remote Inference
2/ Locally hosting SLMs using vLLM/Ollama
3/ Agentic search with SLM Local Inference
4/ Improving relevance with user and business contexts
5/ Fine-tuning SLMs for domain-specific query re-writing via Axolotl/LLaMA-Factory

Keynote: To Nemotron and Beyond: Building the Open Source AI Ecosystem - Chanran Kim, Senior Developer Relations Manager, NVIDIA

Wednesday August 12, 2026 09:10 - 09:25 KST

Grand Ballroom 2-3

The era of open weights has arrived — and it is reshaping every layer of the AI stack, from chips and infrastructure all the way up to the applications that create real-world value.
This transformation has deep roots. Over two decades ago, NVIDIA opened up GPU computing with CUDA, laying the foundation for the developer ecosystem that would eventually power the AI revolution. That same philosophy continues today — through the Nemotron model family, NeMo Agent Toolkit, and Cosmos — contributing to a growing open stack that any developer, researcher, or startup can build on.
We are now entering the era of agentic AI, where open-source stacks enable developers to go beyond inference and build systems that reason, plan, and act. The tools are open. The models are open. The opportunity is now.
This session is an invitation — to understand the open-source AI landscape, to see where it's headed, and to be part of what comes next.

Zephyr RTOS: 10 Years After Applying OSS Best Practices - Kate Stewart, The Linux Foundation

Wednesday August 12, 2026 09:30 - 09:45 KST

Grand Ballroom 2-3

Zephyr initially set out to solve a problem that many embedded teams quietly struggled with: how to build dependable real-time systems without being locked into a single vendor, toolchain, or proprietary stack. The project introduced a new model built around portability, adoption of open source and security best practices, modern tooling, and a shared ecosystem of drivers and middleware.

From the start, there was the commitment from the start apply known best practices to its development. While Zephyr is a different code base, a lot of the lessons learned from developing the Linux Kernel were applied. The project has also focused on incorporating security best practices from the start which now enables it to make compliance easier for manufacturers looking to conform to the emerging Cybersecurity Resilence Act (CRA).

Best practices have also enabled the project to work towards achieving formal safety certification for 61508 and 26262. The project has achieved 61508 concept approval at this point, as is working towards formal certification, using a combination of traditional V-Model analysis, and innovative techniques to keep up with the speed of open source development.

Keynote: Building Trust in the Age of AI: From Data Openness to Responsible Innovation - Dr. Honglak Lee, President and Chief AI Officer, LG AI Research

Wednesday August 12, 2026 10:10 - 10:25 KST

Grand Ballroom 2-3

This presentation examines the evolving role of open data in the next phase of artificial intelligence development, and the growing imperative to align innovation with trust. As AI systems become increasingly data-driven, the quality, origin, and governance of data are emerging as foundational issues that will shape not only technological progress, but also public confidence and global competitiveness.
The talk situates these developments within a broader shift toward greater transparency and accountability in AI, reflected in emerging policy directions such as the EU AI Act and Korea’s Korean AI Basic Act. Rather than viewing openness as a risk to be constrained, it explores how responsible data practices and shared governance approaches can enable wider participation in AI development while maintaining integrity and trust.
Ultimately, the presentation argues that the future of AI will depend not only on model performance, but on the strength of the underlying data ecosystem. Building sustainable trust around open data—through transparency, collaboration, and accountability—will be critical to unlocking the full potential of AI at scale.

Connecting the Dots With Context Graphs - Stephen Chin, Neo4j

Wednesday August 12, 2026 14:55 - 15:25 KST

Grand Ballroom 2-3

AI systems need more than intelligence; they need context that persists. Without it, even strong models can misinterpret information, lose decision rationale, or repeat the same mistakes. Context Graphs have emerged as a practical pattern for agentic AI: a living graph that captures not only what was retrieved or known, but how context led to actions through tool calls, constraints, policies, and outcomes, stitched across entities and time so precedent becomes searchable.

This talk explores context engineering as the discipline of designing that context layer, and shows how context graphs complement retrieval by enabling multi-hop, structured context assembly (building on GraphRAG-style hierarchical summaries) while improving explainability and evaluation. Attendees will leave with a practical understanding of how to build context pipelines that combine contextual retrieval with persistent memory and provenance, and why context graphs are becoming central to trustworthy, enterprise-ready AI systems.
