Introducing

Agent reliability

The complete platform for trustworthy agentic AI.

Observe, evaluate, guardrail and improve agent behavior across every step.

Enable low-cost production monitoring and real-time guardrailing for every AI system without the GPT-sized bill.

Introduction

Why agent reliability matters

As AI agents have become more autonomous and multi-step in nature, their failure modes have become increasingly complex.

One bad action can expose data or cost real money, and guardrails must trigger before the tool executes. You need targeted visibility into agent behavior, especially when agents take real-world actions.

Debug agents faster

Traditional trace views collapse under complex workflows. Leverage intuitive interfaces to get the observability you need into how your agent made it's decisions.

Graph view

Renders every branch, decision, and tool call so you see the exact path an agent takes, and where it veers off, at a glance.

Ecosystem integrations

Galileo's flexible platform integrates with your favorite tools, and leverages open standards like open telemetry to let you bring your preferred frameworks, models, and more.

Insights engine

Continuous agent insights

Our AI Insights dashboard, built into graph view, pinpoints what went wrong, why it happened, and what to do next. Automatically surfaces high-impact issues across your traces.

Session-level summaries

Quick context around agent behavior

Actionable suggestions

Concrete fixes for tool errors, broken flows, and performance issues

Linked evidence

Jump straight to the trace or span where it happened

Galileo’s Insights Engine makes it easy for you to debug your agents, with whichever interface makes sense for your system.

Trusted by enterprises, loved by developers

Out of the box metrics

Our agent metrics cover flow adherence, task completion, conversation quality, and more, giving you insights into each span, trace, and full session.

Metric

What it Detects

Tool Error Rate

Detects whether the Tool executed successfully (i.e. without errors).

Tool Selection Quality

Evaluates whether the agent selected the most appropriate tools for the task.

Action Advancement

Measures how effectively each action advances toward the goal.

Action Completion

Determines whether the agent successfully accomplished all of the user’s goals.

*Conversation Quality

How effective, consistent and friendly were the agent responses?

*Agent Efficiency

The average number of exchanges to task completion could help rank how quickly an agent is able to complete user requests.

*Agent Flow

A binary evaluation metric that measures the correctness and coherence of an agentic trajectory

*Flow Adherence

Did all nodes get invoked in the right order?

*Intent Change

Measures shift in the user's primary conversational goal or workflow during a session, relative to their initial stated intent.

*available upon request

Customize to your requirements

Create custom metrics specific to your needs with our metrics IDE.  Leverage code based metrics, LLM-as-a-judge, or our custom Luna-2 SLMs to get exactly the data you need, whether for the whole agent session, or particular steps.

Luna-2

Continuous evaluations

Our Luna-2’s SLMs are purpose-built for always-on evaluations.

Run 10–20 sophisticated metrics simultaneously with sub-200 ms latency, even at 100% sampling rates. Enable low-cost production monitoring and real-time guardrailing for every AI system, without the GPT-sized bill.

Multiturn agents never follow a single script; your tests can’t either. Here’s how Luna-2 fixes it:

Agents can accomplish the same outcome in many valid ways, so “golden flows” alone don’t cut it

Span-level checks miss slow-burn issues like drift, redundancy, or unsatisfied goals across the dialogue

Luna-2’s session metrics (conversation quality, intent change, efficiency, and compound-request resolution) capture the whole journey, not just a single turn

“The tools Galileo provides through its platform ensure that people can build the agentic systems they need, scale those systems, and do so in a way that not only improves user experience but also helps grow the companies and brands behind these products.”

“We’re excited that Galileo brings deep expertise in defining and recommending metrics for agents—helping us build systems that are more predictable and reliable.”

Guardrailing agents in production

AI systems can misbehave at any step, leaking PII, hallucinating answers, or accepting hostile prompts. But LLMs are too slow and costly to effectively guardrail in production.

Protect your AI agents from malicious user behavior, and from their own mistakes with real-time guardrails powered by our Luna-2 models.
