The Only Extensive Guide On LLM Monitoring You Will Ever Need

The next decade is marked by advancements in AI not just in terms of functionality and use cases but accountability and transparency as well. We are fast moving towards the age of XAI or Explainable AI, where we hold AI models accountable for the decisions they make.

When rationality becomes the fulcrum of AI functioning, consistent observation of LLMs becomes inevitable. With each user prompt being different from the other, it’s a perpetual learning process for LLMs. As enterprises rolling out such models, it’s on us to ensure they are perennially relevant, fair, and precise.

This is taken care of by the process called LLM monitoring. Similar to how we demystified LLM evaluation in our previous blog, we will extensively explore what LLM model monitoring is all about, the use cases, its importance, and more.

Let’s get started.

LLM Monitoring: What Is It?

Like the name suggests, it is the systematic process of tracking the performance, effectiveness, stability, reliability, and other critical aspects of functionality through distinct tools, frameworks, and methodologies. There are diverse metrics LLMs are monitored on and the weightage of each metric depends on the domain or purpose it is deployed in.

For instance, the monitoring metrics for a model deployed in healthcare is different from that of the one deployed in a CRM.

In simple terms, LLM monitoring involves the tracking of:

• How accurate its responses are in terms of relevance, factualness and precision
• How long does a model take to generate a response
• Any innate bias or patterns of it in its responses
• How well does a model understand different languages, tonalities, and prompts
• Does it provide contextually relevant responses; like identifying a sarcastic prompt and more

How Beneficial Is LLM Monitoring When You Already Have LLM Monitoring?

One of the most common questions in this space is whether you actually need to constantly monitor your LLMs while you have evaluated them before launching.

The simplest answer is a resounding yes.

LLM evaluation only ensures adequate and competitive functionality of your models but its relevance in its application only gets strengthened by consistent fine-tuning stemming from monitoring. Apart from performance optimization, there are several compelling reasons why your models need to be monitored such as:

• Hallucinating models, where they sometimes go berserk and present irrelevant and misleading responses in different tangents from the prompt presented
• Hacks and prompt injections that involve the feeding of malicious prompts that can lead to the LLM generate deceptive and harmful outputs
• Training data extraction or fetching sensitive data through specific prompts adept at bypassing common LLM sensibility and discretion and more

If you observe, a live model is prone to innumerable risks and adversities that demand consistent observation, tackling, and mitigation. This is exactly why LLM model monitoring becomes inevitable.

Understanding The Difference Between LLM Monitoring And LLM Observability

LLM monitoring and observability are two commonly misinterpreted terms and rightfully so as monitoring a model loosely translates to observing them for errors and feedback. However, when you explore in depth, the differences are stark and distinct.

From the breakdown so far, we know that LLM monitoring is the process comprising tools and methods to track LLM performance. A step further to this is LLM observability. While the former answers the how, observability answers the why.

Let’s explore this a bit further.

What It Does

This process offers developers and stakeholders a deeper understanding of a model’s behavior. This is more diagnostic in nature that provides holistic prescriptive insights on the functioning of a model.

LLM observability collects a wide spectrum of data from metrics, traces, logs and more to understand issues and resolve them. For instance, if LLM monitoring gives insights on whether a model is facing issues in latency, LLM observability retrieves information on why it is happening and how it can be fixed.

In a way, LLM observability is a subset of model monitoring that solves for a greater challenge.

Data Cleaning

When training your models, ensure you sanitize your training data so sensitive information that can be identifiable is removed. One of the advantages of sourcing data from experts like Shaip is that data is sanitized to ensure optimum privacy and security. This only adds to airtight compliance of mandates specific to domains as well.

Leverage Security Tools

Diverse security tools are available that specialize in protecting AI systems and LLMs. You can harness the potential of such tools to detect anomalies and mitigate issues.

2-Factor Authentication For Sensitive Actions

At times, LLMs are pushed to take some critical actions that may linger in the gray areas of being problematic. To avoid lawsuits or legal consequences, you can add a two-step authentication system, where the model warns users of their actions and asks for a confirmation if they intend to go ahead.

Containing LLM Actions

When developing, you can also limit the actions your models can perform so they don’t trigger unintended consequences. This could be validating input and output, limiting revealing information to 3rd party databases and more.

One of the best ways to stay ahead of concerns is staying abreast of latest advancements and developments in the LLM space. This is specifically critical with respect to cybersecurity. The wider your understanding of the subject, the more metrics and techniques you can come up with to monitor your models.

We believe this was a kickstarter guide in helping you grapple the complexities of LLM model monitoring and we are sure you will take it forward from here on the best strategies to track, safeguard, and optimize your AI systems and models.
