Non-Determinism
Agent systems do not behave deterministically, so reliability has to be engineered around variance in output rather than assumed from the code path.

Our last event filled AWS Builder Loft in San Francisco to capacity.
Agent Engineering HQ runs San Francisco. London events run with London Agentic AI. Both hold the same standard of technical depth.
Home base of Agent Engineering HQ. Practitioner forums on harness engineering, memory engineering, inference engineering, and more.
Events with London Agentic AI, the UK's biggest Agentic AI community, including the AgentEng London Conference 2026.
Agents are not features. They are long-running systems with their own development lifecycle, and they need their own engineering discipline.
Agentic systems behave differently from traditional software. A response can look successful and still fail the task. Behaviour drifts. Trajectories matter as much as outputs. These properties demand a dedicated Agent Development Lifecycle (ADLC), distinct from the traditional software development lifecycle.
The ADLC covers building, testing, deploying, and monitoring agents in production, with iteration and governance running as continuous layers throughout. Production signals feed back into evaluation. Traces drive improvement. Governance keeps the system trustworthy.
Agent Engineering is the practice of designing, building, evaluating, and operating AI agents across that lifecycle. It applies to every category of agent, from coding and research agents to customer-facing, domain-specific, and autonomous multi-agent systems.
AgentEng exists to define and advance this discipline. We bring together the practitioners building the tools, frameworks, and supporting infrastructure that make every phase of the ADLC work in production.
Agent systems do not behave deterministically, so reliability has to be engineered around variance in output rather than assumed from the code path.
Agent behaviour follows the specification it is given. Precise task definitions and planning up front produce more predictable results at runtime.
Users can submit any input, so conventional test coverage does not hold. Behaviour is better understood through evaluation against production traffic.
Compute, budget and human review are finite resources, and allocating them across agent runs is a core operational concern at scale.
Engineering work shifts from writing code towards designing the reviewers that check it, using validation loops and automated pull request gates.
Agents working together need defined communication patterns, with parallel and sequential workflows arranged to avoid conflicting or duplicated work.
The engineering disciplines that form the backbone of production-grade Agentic AI.
Writing effective prompts, system instructions, and prompt patterns. Covers structured outputs, few-shot design, prompt optimization, and LLM-native communication.
Shaping what an agent sees at runtime. Covers context construction, compression, grounding, retrieval, and MCP (Model Context Protocol).
Defines the execution environment around an agent. Wires models to tools, policies, sandboxes, and execution constraints.
Measuring agent behavior in non-deterministic systems. Covers evaluation frameworks, behavioral testing, LLM-as-judge, and reliability benchmarks.
How agents store, retrieve, and evolve state over time. Covers short-term vs long-term memory, retrieval strategies, and personalization.
Serving models efficiently in production. Covers GPU/hardware selection, inference engines (vLLM, SGLang, TensorRT-LLM), latency budgeting, batching, and cost optimization.
Designing the agent's run loop: the iterate, observe, and act cycle. Covers control flow, stopping conditions, retries, self-correction, and long-running autonomous loops.
Automating the entire software development lifecycle and engineering with AI agents.
Improving the coding capabilities of models and agents. Covers agentic coding, coding agents, code generation quality, and AI-assisted software development.
Standing up the protocol layer agents talk over. Covers MCP, ACP, A2A, A2UI, transport and auth choices, versioning, and cross-vendor interoperability.
Building agents with graphs. Covers graph databases, knowledge graphs, graph retrieval, and modelling agent state and execution as graphs.
Agentic search techniques and the retrieval layer underneath them. Covers query planning, ranking, hybrid search, and improving agent behaviour through better search.
Watch our agent swarm coordinate in real-time to create the most technically rigorous Agentic AI conference.

Production patterns, failure analysis, and scaling strategies, presented by the engineers who build these systems.
From frameworks and infrastructure to models, tools, and platforms.
Agent Engineering surfaced independently across practitioner communities, platforms, and research.
AgentEng brings these conversations together, focused on practice over promotion.
