Sponsored Session: From Clicks to Rankings: Building a Learning-to-Rank Pipeline with OpenSearch - West Kim, AWS

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

Rose

Search relevance improves when ranking reflects how users actually interact with results. OpenSearch provides three plugins that work together to enable this: User Behavior Insights (UBI) collects click and query data, Search Relevance Workbench (SRW) evaluates ranking quality, and Learning to Rank (LTR) applies machine-learned models to reorder results. This session walks through the full workflow: collecting user behavior data with UBI, training an XGBoost-based ranking model, and deploying customized search rankings using the LTR plugin.

Sponsored Session: Trust by Design: Engineering Reliable Enterprise AI Workflows with Open Source - KyoSeok Kim & Suyeon Woo, IBM

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

Rose

When enterprises bring AI into real-world operations, reliability challenges extend far beyond hallucinations and response accuracy. Document structure and meaning can be lost during processing, retrieval may fail to provide sufficient grounding, and models may violate business rules or operational constraints. As agents connect to enterprise systems, additional risks emerge, including unauthorized tool calls and actions that are difficult to trace or audit.
These challenges cannot be addressed by adding a guardrail at the final stage. Reliability must be designed across the entire workflow, from document understanding and retrieval to reasoning, generation, and execution.
This session presents an open-source reference architecture that combines document representation with Docling and DocLang, grounded retrieval and reasoning with OpenRAG and Granite, requirement-driven generation and validation with Mellea, and controlled, observable tool integration with ContextForge.

LLMs Change — Where Should Knowledge Live? (Lessons From SBOM) - Koji Annoura, Annoura Office

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

Rose

Large Language Models (LLMs) are widely used to search, summarize, and generate answers. They are powerful, but results are not always stable and can be difficult to verify.

Many systems use Retrieval-Augmented Generation (RAG) to connect LLMs with external data. This helps, but does not fully solve the problem. The same question can produce different answers depending on the model or context, making knowledge hard to manage.

This raises a simple question: where should knowledge be managed?

A similar issue exists in software supply chains. SBOM (Software Bill of Materials) makes components and relationships visible, but is often treated as static data.

Based on hands-on experience designing graph-based knowledge systems, this session introduces a design approach: managing knowledge outside LLMs as structured, persistent data.

We discuss lessons from SBOM and how graph-based approaches—using technologies such as SQL/PGQ or GQL—can help understand relationships and trace changes.

The focus is a practical way of thinking for more open and sustainable knowledge practices.

From Black Box To Insight: Observability for AI Agents in Production - Mostafa Radwan, Datadog & Brandon Kang, Akamai Technologies

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

Rose

AI agents are quickly moving from prototypes to production systems that manage APIs, tools, and complex reasoning tasks.

Once these systems are deployed, they often act like black boxes, hiding failures, slowdowns, and unexpected behavior.

This session will show you how to add observability to agentic systems with open-source tools and cloud-native tech.

Brandon and Mostafa will break down the lifecycle of an AI agent, covering prompt execution, tool invocation, memory access, and multi-agent coordination, and demonstrate how to make each stage observable.

Using a practical, architecture-focused approach, they will show how to:

- Trace agent workflows across distributed systems
- Monitor latency and token usage
- Detect anomalies such as hallucinations, tool misuse, and runaway behavior.
- Connect LLM behavior with infrastructure metrics like GPU, container, and network data.

They will also present a complete reference architecture that uses open-source projects including OpenTelemetry (OTel), Prometheus, Grafana, and some new tools for LLM observability.

Attendees will learn practical ways to build transparent and reliable production AI agent systems.

Exploring HiFloat8: A Tapered Format Complementing the FP8 Ecosystem for Robust Model Training - Yun Zhao & Haonan Zhang, Huawei

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

Rose

Standard FP8 formats suffer from frequent gradient overflows and heavy reliance on complex Delayed Scaling, which often lead to training instability or suboptimal convergence in large models. This session introduces HiFloat8 (HiF8) — a tapered precision format that offers an alternative approach to managing dynamic range. This "natural" alignment with neural network weight/gradient distributions allows HiF8 to capture high-magnitude outliers without the aggressive scaling required by standard FP8.We explore how HiF8 can works in the training and inference procedure.We will demonstrate the implementation of HiF8 within the ecosystem. They allow developers to evaluate performance of Hif8 on GPUs. Also, we will give an analysis of training stability and final loss parity where HiF8 provides relatively the same accuracy and 1.5-1.7 times GEMM performance than FP16. Finally, we will share insights from our ongoing collaboration on dedicated hardware support for HiF8.

How x402 Brings Open Source Governance to Payments - Junhyeok Yoo, Four Pillars

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

Rose

In April 2026, x402 joined the Linux Foundation with over 20 founding members. It is the first payment protocol under open source governance at the Linux Foundation.

x402 activates HTTP 402 "Payment Required," reserved in 1997 but never used. A server responds with 402 and payment terms, the client settles on-chain, the resource is delivered. Apache 2.0, zero protocol fees, chain-agnostic, no single-organization dependency.

Part 1: Why now. Every internet layer runs on open protocols except payments. That breaks when AI agents must pay at machine speed. We map the agentic payment stack and ask: is it open, who governs it?

Part 2: How x402 works. HTTP 402 challenge-response, stateless architecture, one middleware line to gate any API, production deployments today.

Part 3: Bottom-up to foundation. x402 was open-sourced, developers adopted it, major infrastructure providers shipped native support, competing protocols chose to integrate x402 rather than build a rival. Then it moved to the Linux Foundation.

Part 4: What comes next. The protocol is early. Foundation governance changes the signal. We examine what sustained adoption requires.

When Semantic Search Breaks: RAM Walls, Silent Failures, and the Architecture Decisions That Actual - Jeevan D C, Entain

Wednesday August 12, 2026 11:00 - 11:30 KST

Rose

The team shipped semantic search. It worked. Then came 100M vectors, a RAM bill that tripled overnight, filtered queries silently returning zero results, and a proposal to "just add Pinecone alongside Postgres."

This talk is for engineers who've already built the thing and now need to scale it without burning the budget or the team. We'll do the RAM math that should happen before any architecture decision, walk through quantization strategies that deliver 32x compression with 95%+ recall, show why filtered search is the #1 silent production failure, and lay out when DiskANN, hybrid BM25+vector search, or a specialized vector DB actually makes sense — and when it doesn't.

Live demos included. Decision matrices to take back to the team on Monday. No hype, just trade-offs in plain English.

Simplifying Edge Compute for Open-Source AI - Reza Jelveh, Dynamia

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

Rose

The open-source community is rapidly producing powerful, autonomous AI agents capable of complex reasoning and tool use, such as Hermes and OpenClaw. However, the barrier to entry for deploying these agents remains high, often requiring complex infrastructure setups and significant computational resources. To truly democratize access to agentic AI, we must simplify the deployment and management of edge compute.
This technical deep dive breaks down the complexities of orchestrating edge resources for autonomous agents. We will focus on practical strategies for deploying hybrid Kubernetes clusters designed specifically for local AI workloads. The session will highlight the critical role of GPU management, demonstrating how to optimize hardware utilization through memory slicing and time-sharing with open source projects. By providing a blueprint for efficient edge orchestration, this talk aims to empower developers and builders to deploy sophisticated open-source agents without the need for massive cloud budgets.

AI-Powered Open Source Risk Management: ISO Self-Certification Kit and 5-Level AI Coding Governance - Haksung Jang, SK Telecom

Wednesday August 12, 2026 13:35 - 14:05 KST

Rose

Trusted OSS is an open-source self-certification kit that guides any organization from zero to ISO/IEC 5230 (license compliance) and ISO/IEC 18974 (security assurance) conformance using AI agents.
No prior expertise required.

Built by the OpenChain Korea Work Group and released under CC BY 4.0, the kit features:

• AI agents (Claude Code) that auto-generate company-specific compliance artifacts: OSS policy, SBOM, vulnerability response procedures, training curriculum, and conformance declaration
• DevSecOps pipelines (SAST, SCA, secret detection, IaC) ready to drop into any CI/CD environment
• A 5-level AI Coding Governance Maturity Model — from ad-hoc prompting (Level 1) to AI-augmented defense (findings-driven review, AI fuzzing) and continuous auto-remediation (Level 5).

In this session, I'll walk through how any team can go from no compliance process to a fully documented, self-certifiable program in hours, not months. I'll also share how we're using AI to close the compliance skills gap across Korean enterprises and SMEs — making OpenChain certification accessible to all.

Attendees leave with a working toolkit they can clone and run today.

How To Make AI-Assisted OSS Contributions Review-Ready - Jaewoo Choi, Hyundai Autoever

Wednesday August 12, 2026 14:15 - 14:45 KST

Rose

AI coding tools can generate patches quickly, but maintainers still cannot merge a PR on generated code alone. They need evidence, what was reproduced, what changed, how it was validated, and whether the contributor actually reduced review work instead of shifting it downstream.

In this session, I draw on recurring patterns from reviewing and maintaining Argo CD contributions to show why many AI-assisted PRs stall and what makes others move quickly. I present a simple four-stage framework for review-ready OSS contributions, Set up the environment, validate the problem before changing code, harden the fix with tests and checks, and submit a PR with enough context and proof for efficient review. Attendees will leave with practical guidance they can use immediately to improve contribution quality and reduce maintainer burden.

Scaling Open Source Compliance With Argus - Luyen Vu, SAP

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

Rose

Managing open source compliance at scale is no longer a spreadsheet problem — it’s an infrastructure and intelligence challenge. This session introduces Argus, an always-on compliance and code intelligence platform built for OSPOs and security teams managing hundreds of repositories.

Argus unifies license scanning, cryptographic analysis, AI/LLM dependency detection, infrastructure checks, and coding agent artifact discovery into a single pipeline. Its hybrid architecture combines Python orchestration, a high-throughput Rust engine for large repositories, and an LLM-powered analysis layer that turns raw findings into actionable insights.

We’ll demonstrate how techniques like blobless git cloning, bounded concurrency, and per-scanner task tracking enable scanning repositories with 100K+ files in minutes. Attendees will learn practical patterns for automated license resolution, large-scale crypto detection, and generating compliance reports that teams actually act on.

Finally, we’ll share lessons from integrating open source and commercial tools in a production OSPO — and how an agentic approach helps small teams scale compliance without increasing headcount.

Building Reliable AI Agents: An Open Source Approach To Evaluation and Observability - Sho Tanaka, Snowflake

Wednesday August 12, 2026 15:55 - 16:25 KST

Rose

Building AI agents is easier than ever with open source tools, but ensuring their reliability in production remains a major challenge. Unlike traditional software, AI agents are non-deterministic, making simple pass/fail testing insufficient.

This talk introduces a practical approach to evaluation and observability for AI agents, combining open source tools such as TruLens with agent architectures inspired by AgentGPT.

We will demonstrate how to instrument agent workflows, capture execution traces, and implement evaluation metrics such as faithfulness, tool selection accuracy, and answer relevancy. Attendees will also see how to visualize agent behavior and identify failure points across retrieval, reasoning, and generation layers using a lightweight dashboard.

Finally, we show how to build a feedback loop to iteratively improve agent performance, and share a reference implementation (GitHub) that can be reused with different agent frameworks.

Eval-Driven Development: Mastering Agentic Tracing and Expert-Aligned Judges With MLflow - Vincent Caldeira & Sharon Dashet, Red Hat

Wednesday August 12, 2026 16:35 - 17:05 KST

Rose

Building AI agents is easy, but ensuring their reliability is hard. Because agents operate in open-ended, non-deterministic environments, traditional Test-Driven Development (TDD) falls short. The solution is Eval-Driven Development (EDD), a paradigm that embeds continuous evaluation throughout the agent lifecycle.

This talk explores how to operationalize EDD. First, we examine the critical role of observability. Evaluating just a final output is insufficient for multi-step workflows. We show how OpenTelemetry (OTel) compatible tracing exposes internal reasoning and tool usage for granular debugging.

Next, we tackle scaling evaluation via LLM-as-a-Judge. Since uncalibrated judges often miss domain-specific nuances, we demonstrate aligning custom judges with human experts. Using open-source MLflow, attendees will learn to capture traces, collect expert feedback, and use alignment optimizers to create expert-aligned evaluators.
