Galileo provides an AI observability and eval engineering platform for teams building generative AI and agentic applications. Its software helps organizations create and manage evaluation data, trace workflows, monitor live traffic, detect quality and safety issues, and turn approved evaluations into production guardrails. The platform is designed for agents, chatbots, and RAG systems that need more than basic model monitoring.
The company’s offering centers on Agent Reliability and the Galileo Evaluate, Galileo Observe, Galileo Protect, and Galileo Signals product lines, with Luna-2 small language models powering low-latency, lower-cost evaluations and runtime protection. Galileo serves both individual developers and enterprise AI teams with cloud-hosted, VPC, and on-premises deployment options, plus procurement through major cloud marketplaces.
Offerings, Capabilities, and Integrations
Galileo combines evaluation, observability, runtime protection, and failure-pattern detection in a single workflow. Teams can start with out-of-box evaluators for RAG, agents, safety, and security, then add custom metrics, tune them from live feedback, and reuse the same logic from development through production. The platform also supports alerts, root-cause analysis, graph and trace views, and production monitoring across 100% of traffic when paired with Luna-2.
Integration is developer-oriented and framework-agnostic. Galileo provides Python and TypeScript SDKs, APIs, OpenTelemetry and OpenInference support, and integrations for LangChain, LangGraph, CrewAI, OpenAI Agents SDK, Google ADK, Microsoft Agent Framework, Strands Agents, Vercel AI SDK, and A2A. It also connects to major model ecosystems including OpenAI and Azure, Google Vertex AI, and AWS Bedrock, and supports enterprise deployments in hosted, VPC, Kubernetes, and air-gapped environments.
Products and Services
- Agent Reliability: Flagship platform for observing, evaluating, guardrailing, and improving AI agents, with graph-based tracing, agent-specific metrics, and production-scale reliability workflows.
- Galileo Evaluate: Collaborative evaluation workbench for prompt, model, chain, and agent experimentation, with tracing, experiment management, golden test sets, and custom or research-backed metrics.
- Galileo Observe: Production observability module for monitoring live GenAI applications, tracking quality and safety metrics, setting alerts, and debugging issues through root-cause analysis.
- Galileo Protect: Runtime protection layer that intercepts inputs and outputs, applies rulesets and stages, and can block prompt injections, PII leakage, toxic content, and hallucinations.
- Galileo Signals: Failure-pattern detection system that analyzes production traces to surface unknown issues, cluster recurring failures, and accelerate creation of new evaluations from discovered signals.
- Luna-2: Family of small language models for low-latency, cost-efficient evaluation and guardrailing, including enterprise support for custom fine-tuning and agent-specific metrics.
- Agent Control: Open-source control plane for centralized policy enforcement across agent fleets, allowing teams to apply governance controls without redeploying each agent.
- Galileo LLM Fine-Tune: Beta fine-tuning product for improving model quality through training-data inspection, data error detection, sample editing, export, and retraining workflows.
Target Customers
Galileo targets teams moving GenAI and agentic systems from prototype to production. Core users include AI engineers, ML engineers, software engineers, product managers, and subject matter experts who need a shared system for evaluation, annotation, monitoring, and governance.
Its strongest fit is organizations operating customer-facing or business-critical chatbots, RAG applications, and autonomous agents where accuracy, safety, latency, and policy control matter. Galileo serves both developers and small teams through a free tier and larger enterprises through VPC, on-premises, and enterprise security options, with customer evidence spanning startups through large Fortune-scale organizations across industries such as education, communications, financial services, media, entertainment, and consumer products.
