# When AI Fails: How FAILS Helps Track and Analyze LLM Service Outages  
## Introduction  
AI-powered tools like ChatGPT, DALL·E, and other large language model (LLM) services have become an integral part of our daily and professional lives. Businesses use them for customer support, creative professionals rely on them for content generation, and developers integrate them into coding assistants. But just like any other technology, LLM services are not immune to failures.  
When a major AI tool goes down, it can cause frustration, lost productivity, and even financial losses. Yet, studying and understanding these failures is a challenge—most service providers don’t offer detailed, open-access data on these incidents. Enter **FAILS**—a groundbreaking open-source framework designed to collect, analyze, and visualize LLM service failures.  
This blog post will explore what FAILS does, why it matters, and how it can help researchers, engineers, and everyday users understand and mitigate AI outages.

## Why AI Services Fail (and Why It Matters)  
AI services operate as **complex, large-scale distributed systems**, with different components spread across the globe. This complexity makes them **prone to failures**, which can stem from:  
- **Infrastructure issues**: Data centers, cloud servers, or networks experiencing downtime.  
- **Software bugs**: Problems with the AI models, faulty updates, or system overloads.  
- **External dependencies**: Issues with APIs, third-party dependencies, or cyberattacks.  
When an AI service goes down, it can **cost businesses revenue, frustrate users, and damage trust**—forcing even industry-leading companies to issue public apologies.  
Yet, most failure analysis tools available today are either **private, enterprise-focused, or provide limited data**. General outage tracking services like Downdetector offer user-reported issues but lack detailed insights. This gap in open-access failure analysis motivated researchers to develop FAILS.

## Meet FAILS: The Open-Source Solution for AI Outages  
FAILS (**Framework for Analysis of Incidents on LLM Services**) is the **first open-source tool designed to collect, analyze, and visualize LLM service failures**. It scrapes incident reports from major AI service providers—including OpenAI (ChatGPT, DALL·E), Anthropic (Claude), Character.AI, and Stability.AI—and provides detailed insights into:  
1. **How often failures occur** – analyzing the **Mean Time Between Failures (MTBF)**.  
2. **How quickly services recover** – measuring the **Mean Time to Recovery (MTTR)**.  
3. **Failure trends and patterns over time** – spotting recurring issues.  
4. **Which services are affected together** – understanding dependencies and cascading failures.  
And the best part? **FAILS integrates LLM-powered analysis**, making it easier than ever to interpret the data with an AI chatbot that can break down failure insights.

## How FAILS Works  
### **1. Automated Data Collection & Cleaning**  
FAILS **scrapes status pages from major LLM providers** to collect real-time and historical incident reports. Since service providers use different formats and reporting styles, the tool **cleans and standardizes the data**, making it useful for comparison and analysis.  
### **2. Detailed Failure Analysis**  
FAILS performs **17 different types of failure analyses**, including:  
- **MTBF (Mean Time Between Failures):** The average time between service outages.  
- **MTTR (Mean Time to Recovery):** The average time it takes to fix an issue.  
- **Co-occurrence of failures:** Identifies which services tend to go down together.  
For example, FAILS found that **Character.AI and Stability.AI tend to have longer times between failures**, while **OpenAI and Anthropic experience more frequent outages but recover faster**.  
### **3. AI-Powered Insights**  
Understanding **technical failure metrics can be tricky**, so FAILS integrates **AI-driven explanations**. Users can ask a chatbot questions like:  
- *"How many incidents happened in the last six months?"*  
- *"Which provider has the shortest recovery time?"*  
- *"What are the most common failure patterns seen in OpenAI services?"*  
This AI-assisted interaction helps **make complex failure data accessible to researchers, engineers, and even non-technical users**.  
### **4. Interactive Data Visualization**  
FAILS isn’t just about numbers—it generates **easy-to-read plots and graphs** to visualize failure trends over time.  
- **Time-series plots** highlight how outages have changed historically.  
- **Heatmaps** show service dependency and co-occurrence of failures.  
- **CDF charts** illustrate how long different providers take to recover from failures.  
Users can even download these charts for reports and presentations.

## Why FAILS Matters  
1. **Empowering Transparency in AI**  
   - Many AI companies publicly report failures, but they don’t make it easy to analyze trends. FAILS brings transparency to the reliability of LLM services.  
2. **Helping Businesses & Researchers**  
   - Businesses relying on AI tools can use FAILS to choose **more reliable** services. Researchers can leverage FAILS **to improve AI resilience**.  
3. **Reducing AI Downtime in the Long Run**  
   - By identifying **common failure patterns**, AI developers can **prevent recurring issues** and improve service availability.  
4. **Bringing AI & Users Closer**  
   - With FAILS’ interactive chatbot, even non-technical users can **understand AI failures more easily**—bridging the gap between AI research and real-world application.

## The Future of FAILS  
The team behind FAILS is working on **several exciting improvements**, including:  
- **Real-time failure prediction**: Using AI to predict downtime before it happens.  
- **Better AI-powered explanations**: Improving LLM-assisted analysis with advanced models.  
- **User-reported failures**: Integrating third-party reports from social media and Downdetector.  
With these updates, FAILS could become the **go-to tool for AI reliability analysis**, helping keep the AI services we depend on more predictable and resilient.
