Agentic AI in production: Six industry examples & the infrastructure behind them

You've chained together a few LLM calls, added retry logic, thrown in a tool call or two—and suddenly you're debugging something that looks less like a prompt and more like a distributed system. That's the jump from a single LLM call to an agentic system. Agentic systems don't just generate responses. They plan, act, use tools, and remember what happened along the way. And industry rollouts are already showing up across industries where these capabilities matter.

This article covers what agentic systems actually are, six industry examples, and the infrastructure patterns that help these systems work.

Understanding agentic systems

An agentic system isn't just a smarter chatbot. It wraps an LLM in an execution loop that can plan, use tools, and act on the results, iterating until it gets somewhere useful. The key distinction from a one-shot assistant: agents do things in the world, not just respond to prompts.

Four traits define what makes a system agentic:

• Autonomous decision-making: Agents choose their execution path as they go, not following a fixed script. That means nondeterministic behavior, which breaks standard machine learning (ML) testing assumptions.
• Multi-step reasoning: Agents iterate in sense-think-act loops, re-evaluating after each action. Every LLM call adds latency and cost, so those loops compound fast.
• Tool use: Agents call external systems and data sources to get things done. An agent is only as capable as what it can reach.
• Memory across interactions: State persists across steps, sessions, and agents. That breaks stateless cloud patterns and requires dedicated memory infrastructure.

Those four traits are also what make these systems harder to run than a one-shot assistant.

Adoption is moving fast. 40% of apps are projected to feature task-specific AI agents by end of 2026, up from less than 5% in 2025.

So what do these deployments actually look like? Here are six industries where agentic AI is already in production.

Retail & e-commerce

Retail is a good fit for agentic systems because the workflows are naturally sequential: demand forecasting feeds replenishment, replenishment feeds vendor selection, vendor selection feeds fulfillment. When something breaks or goes stale at any step, it cascades.

Inventory management & demand forecasting

Agents can sit on top of demand prediction models and flag issues as they surface, adjusting replenishment schedules on the fly when a demand surge is burning through stock faster than expected. Walmart built this out using an in-house multi-horizon recurrent neural network with agentic tools on top.

The fuller version stitches together the whole workflow: forecasting, vendor selection, truck building, and issue resolution in a single loop. Wakefern Food Corp. was one of the first grocery retailers to deploy the Afresh solution for this, and Albertsons rolled out the same implementation across departments and all store brands.

Personalized customer interactions & returns processing

Agents are also pushing into the customer-facing side: natural language search, personalized recommendations, and in some cases, checkout. Walmart, Etsy, Instacart, and PayPal are all building shopping workflows through AI engines, with integrations like account linking that give agents access to a customer's full purchase context.

Financial services

Financial services runs on high transaction volumes with strict regulatory requirements attached to almost every decision. That combination of speed and compliance makes it one of the clearest fits for agentic systems.

Fraud detection & transaction monitoring

Agents can correlate account activity, purchase patterns, merchant data, and device information to flag fraud in real time at the point of transaction. The multi-step reasoning matters here: instead of firing static rules, agents assess complex relationships across mass data and adapt to new fraud patterns. Visa's anti-scam unit said it prevented $350M in attempted fraud using GenAI tools for correlation and graphing analysis. Mastercard's Decision Intelligence system uses a similar approach to detect fraud at the transaction level.

Some banks are taking it further by putting agents directly in the customer's hands. NatWest's Cora platform lets customers resolve fraud disputes through natural language conversations, rather than waiting in a phone queue.

Compliance reporting & audit preparation

Compliance is where agents show one of their most valuable traits: full explainability through audit trails. McKinsey describes agentic AI factories that produce summary reports, recommendations, and detailed analyses for each compliance case. The system captures data used, steps followed, agent conversations, and rationales for conclusions, directly addressing regulatory explainability requirements.

That helps explain why expectations in banking are high. 57% of executives expect AI agents fully embedded in risk, compliance, audit, fraud detection, and transaction monitoring within three years. Full autonomy in banking, though, could still take more than five years because of the sector's regulatory environment and legacy systems.

Healthcare

Healthcare adds a constraint the other industries don't share as strongly: human review stays close to the loop by design. Most of these deployments run in HIPAA-regulated environments, which makes that design choice non-negotiable anyway.

Patient intake, scheduling, & care coordination

Intake, scheduling, and care coordination across large provider networks are high-volume, repetitive, and time-sensitive: tasks agents are well-suited to handle. One national outpatient provider operating more than 300 sites deployed the UnityAI platform and reported a 26% improvement in scheduler productivity and a 30% reduction in patient no-show rates. In that same deployment, approximately 90% of tasks were completed without staff involvement.

For care coordination, agents can orchestrate across specialties and decision-makers. Microsoft announced an AI agent orchestrator for cancer care management, with teams at Mass General among the early users exploring it. The orchestrator includes customizable, multimodal AI agents for tumor board coordination and clinical decision-making support.

Clinical documentation & compliance tracking

Agents can listen to clinical conversations in real time and generate structured documentation within existing workflows, replacing the manual note-taking that eats into patient-facing time. The Hospital for Special Surgery is implementing the Abridge platform enterprise-wide for clinical documentation, covering approximately 200,000 patients annually.

On the compliance side, agents can read denial letters, determine missing documentation, assemble corrections, and route to a clinician for approval before submission. Hackensack Meridian Health deployed an appeals workflow agent for this workflow, and claims time dropped from 15–16 days to 1–2 days.

Manufacturing

Manufacturing use cases involve physical equipment, tight scheduling, and supply chains where downtime costs real money.

Predictive maintenance & equipment monitoring

Agents can monitor plant schematics, connect to existing sensor networks, and predict equipment failures before they happen. Technicians get multimodal fault diagnostics instead of manual inspections. One distillery group (William Grant & Sons) deployed this approach and said it could save £8.4M annually through reduced downtime and increased output. The same applies to oil and gas monitoring, where agents handle equipment monitoring and predictive maintenance across remote infrastructure that's hard to staff continuously.

Production scheduling & supply chain coordination

Production scheduling is another fit: coordinating design constraints, resource availability, and delivery timelines across shifting conditions. Siemens introduced AI agents for scheduling within its Industrial copilot ecosystem, with plans to make them available through a marketplace model.

Logistics & supply chain

The same pressure on speed and handoffs shows up in logistics, where delays compound fast and every link in the chain is a chance for something to go stale or slip.

Route optimization & real-time delivery management

At the terminal level, agents can reduce unnecessary moves, improve truck servicing times, and rebalance resources as conditions shift. DP World deployed AI-powered predictive analytics at the Jebel Ali terminal, where the cited source reported a reduction of 350,000 moves annually and a 20% improvement in truck servicing times.

The bigger shift is in replanning speed: instead of requiring humans to respond to disruptions, agents monitor conditions continuously and adjust routes autonomously when circumstances change.

Software development & IT operations

Engineering workflows bring their own version of the same pressure: incidents and deployments already span multiple tools and handoffs. DevOps and site reliability engineering (SRE) teams are a natural fit for agentic systems because incident response and deployment pipelines are exception-heavy, stateful workflows where agents add more value than static automation.

Incident detection, triage, & resolution

Agents can detect service-level objective (SLO) breaches, perform diagnostics like memory dumps and root cause analysis, and triage incidents without waiting for an on-call engineer to context-switch. One SRE agent demo for Java workloads, documented in an InfoQ presentation, showed it completing some diagnostic steps within minutes.

Code review, testing, & deployment pipeline management

Agents can also handle code review by identifying security risks, prioritizing them by severity, and recommending remediations. Some platforms extend this with patching support that applies fixes for remediable issues, while others handle the triage and prioritization layer.

What these examples have in common

Across all six industries, three infrastructure patterns keep coming up.

• Memory and continuity. Agents that can't remember previous steps reconstruct context from scratch on each invocation, making them slow and unreliable. Research on long-running agents identifies memory inflation and contextual degradation as the key failure modes.
• Latency at every step. Every LLM call adds delay, and those delays compound. In one InfoQ benchmark of a Redis-based RAG setup, end-to-end latency measured roughly 1,513ms. Agentic systems with multiple reasoning steps multiply that number fast.
• Shared state between agents. Once agents hand work to each other, shared data becomes the bottleneck. Without fast, consistent state, agents either work with stale data and risk conflicting actions, or wait on synchronous calls that add more delay.

How well you solve these three determines how well your agents hold up outside a demo.

You've made it this far

Now see how this actually runs in Redis. Power AI apps with real-time context, retrieval, and semantic caching.

Agentic systems need fast shared state

Redis fits here because it combines the capabilities agentic systems need in a single platform: short-term memory through in-memory data structures, long-term memory through vector search via Redis Query Engine, operational state through native data structures like hashes and sorted sets, and real-time coordination through streams and pub/sub. That consolidation helps reduce the network hops and moving parts that build up across agent workflows.

For multi-agent systems where repeated or similar LLM calls are common (incident triage, customer Q&A, compliance checks), Redis LangCache provides semantic caching that recognizes when queries mean the same thing despite different wording. In one Redis-reported benchmark, LangCache reported up to 73% lower LLM inference costs without code changes. Redis integrates with popular AI frameworks including LangChain, LangGraph, and LlamaIndex, and supports agentic apps through an open-source Model Context Protocol (MCP) server.

Whether you're building agents for fraud detection, clinical documentation, or deployment pipeline management, the same infrastructure patterns keep coming up. Try Redis free to explore the agent memory stack, or talk to us about building your agentic systems infrastructure.
