LLM monitoring, or Large Language Model monitoring, is the process of overseeing and evaluating the performance of these advanced AI models.
Let's break it down to make it more understandable.
Monitoring Large Language Models like EinsteinGPT—a Salesforce AI tool—means keeping an eye on how well they're doing in real-world tasks.
Salesforce, for example, relies on EinsteinGPT to help with a variety of tasks. These include crafting sales pitches, streamlining sales and support tasks, generating useful content for customers and products, building website features, and summarizing important conversations and documents.
When we monitor LLMs, we focus on several key areas:
Accuracy: We check if the LLM is giving correct and relevant responses.
Response Time: It's important that the LLM replies quickly.
Sentiment: We analyze the tone of the LLM's responses to ensure appropriateness.
Context Relevancy: The LLM's responses must make sense in the given situation.
Perplexity: This sounds complex, but it's about how well the LLM understands different language patterns.
Fairness: We watch out for any biases that might slip into the LLM's outputs, which could be unfair to certain groups.
Additionally, LLM observability involves measuring how the LLM is being used, focusing on:
Latency: How long it takes for the LLM to respond.
Throughput: The number of tasks the LLM can handle in a given time.
While monitoring tends to revolve around the LLM's behavior, observability is more about its operational aspects. It's the difference between asking, "Is the LLM working correctly?" and "How well is the LLM coping with its workload?"
It's common to use 'monitoring' and 'observability' interchangeably, but they do have distinct focuses.
In traditional machine learning, monitoring usually relates to how the data or model might be changing over time, whereas observability deals with how the system is being used. The same distinction applies when we talk about LLMs.
Why Is LLM Monitoring Important?
LLM monitoring is crucial for several reasons, mainly due to the inherent risks and imperfections associated with deploying LLMs in real-world applications.
Firstly, LLMs, despite their sophistication, are not foolproof.
There are specific risks involved:
Prompt Injection: Users can manipulate LLMs by inputting deceptive prompts, potentially leading to incorrect or harmful outputs. The Open Web Application Security Project (OWASP) even ranks prompt injection as a top threat to LLM systems.
Hallucinations: This term refers to the LLM generating nonsensical or irrelevant answers, which can be disconcerting or misleading for users.
Sensitive Data Disclosure: LLMs that are not sufficiently secured may inadvertently expose personal or confidential information, compromising user privacy.
Excessive Agency: Providing LLMs with too much autonomy might result in actions that endanger the security and integrity of sensitive data.
Because of these issues, diligent monitoring is essential. Here’s why:
Preventing Disaster: Consider what might happen if an LLM like EinsteinGPT were to inadvertently release confidential data from Salesforce’s database. Such a breach could be disastrous in sectors like finance or healthcare, where LLMs may advise on financial transactions or medical treatments.
Building Trust: Reliability is key to user adoption. If a system routinely produces inaccurate results, users will quickly lose faith. For instance, if a corporate tool produces unreliable sales pitches or document summaries, users could abandon the tool entirely. Regular monitoring helps ensure the quality and reliability of the system's outputs, fostering trust.
System Improvement: To refine an LLM and address its shortcomings, you need to know how it performs in practice. Without this insight, you can't effectively tackle issues and improve the system.
These production-related challenges are relatively fresh grounds for AI practitioners, who are still grappling with the potential impacts and risks of LLM technology.
The novelty of these risks makes thorough and consistent monitoring not just advisable, but essential to successfully and safely implementing LLMs in any operational context.
When it comes to ensuring the safe and effective use of Large Language Models, several best practices can guide your monitoring efforts.
Here's a distilled list of key recommendations:
Implement Data Sanitization
Cleanse data to prevent the incorporation of users' information into the model's training data. This helps protect privacy and reduces the risk of data leaks.
Restrict LLM Actions
Control the actions that the LLM can perform, especially when interacting with other systems. This means validating both inputs to and outputs from the model to prevent unintended operations.
User Confirmations for Critical Actions
For actions that could potentially be risky or impactful, set up a confirmation step where the user must approve the action, particularly if the LLM can interface with external APIs.
Use Security Tools
Consider adopting third-party tools like Lakera Guard that specialize in AI system protection, to detect threats and issue timely warnings.
Secure The Supply Chain
Evaluate the security protocols of data sources and suppliers associated with your LLM. Make sure to understand and agree with their privacy policies and terms of service
Stay Informed

Disseminate knowledge within your team or user base by leveraging interactive tools such as Gandalf, a game designed to teach about AI security.
Safeguard Against Accidental Data Sharing
Tools like the Lakera Chrome Extension can alert users when they might inadvertently share personally identifiable information (PII) with LLMs, adding an additional layer of security.
Maintain Human Oversight
Keep humans in the loop for feedback on LLM performance. Human judgment is crucial in catching errors that LLMs may not be programmed to recognize
Use Schedulers and Alert Systems
Implement scheduling tools for regular checks and alert systems to promptly flag issues with the LLM. This ensures continuous monitoring and quick response to any potential issue.
Following these strategies will help address the unique challenges associated with LLMs.
As this field of AI continues to evolve, staying informed and adjusting your practices will be essential for maintaining secure, reliable, and trustworthy LLM systems.
LLM Monitoring vs. Evaluation
The processes of evaluating and monitoring LLMs are essential to their successful deployment and operation. It's vital to comprehend their differences to apply them effectively:
LLM Evaluation
The aim of LLM evaluation is to determine the model's performance before it's put to use. This step is critical to ensure the model is set up for success. The primary tools and methods involved include:
Testing Cases: Comparison of the model's outputs against pre-defined correct responses.
Prompt Evaluation: Ensuring that the model's prompts lead to desirable outcomes.
Benchmarking Results: Using reference data and evaluation datasets, such as those provided by Lakera, to compare the model's outputs.
Evaluation focuses on static metrics such as similarity scores, BLEU, ROUGE, and TER, which assess how closely the generated text matches a reference or expected result.
Meanwhile, LLM monitoring is an ongoing activity that takes place after the model has been deployed. Its purpose is to continuously ensure the LLM performs up to standards in a live environment.
Key facets of LLM monitoring include:
Monitoring Prompts: This involves tracking requests, response time, and usage metrics. By doing so, you can fine-tune the effectiveness and efficiency of the model's interactions.
Monitoring Responses: Here, you scrutinize the LLM's outputs for accuracy, relevance, and ethical consistency, looking out for issues such as hallucinations or biases.
Functional Monitoring: It's about observing the LLM's general performance, ensuring robust functioning by watching over practical operational metrics.
Monitoring employs real-time metrics like accuracy, response time, sentiment analysis, toxicity, context relevancy, and fairness. These are key indicators of the model's real-world performance.
Tools such as Haystack and Lakera AI are utilized to monitor context relevance and detect PII in the LLM's interactions, respectively.
The table below summarizes the distinct differences between LLM evaluation and monitoring:
