Mastering LLM Development: Your Recipe for Success in AI

You can meticulously train models, feeding them data like secret spices, but how do you truly know if the AI delivers true value?

Similar anxieties plague businesses developing a large language model (LLM). The generative nature of LLMs makes it hard to measure and evaluate the quality of the outputs they generate.

ℹ️ Why This Matters Today

Well-defined evaluation metrics like accuracy, precision, and recall provide developers with clear feedback on model performance, which allows them to apply a more rigorous, data-driven approach to testing and improving your AI applications.

Without reliable evaluation methods, your LLM could end up serving subpar "dishes" that alienate customers and tarnish your brand.

We recently had a chat with Nir Gazit from Traceloop – a company specializing in LLM observability and testing solutions – to get a more in-depth understanding of this critical issue: the lack of rigorous testing and evaluation in LLM development. 

This "trial and error" approach leads to several problems:

1. Pushing untested LLMs to production risks poor outputs, negative user experiences, and potential harm.

2. Manual testing often misses deeper complexities, biases, or unintended consequences.

3. Overreliance on unproven capabilities creates unrealistic expectations and hinders responsible development.

⚒️ Actionable Steps

Nir advocates for backtesting and monitoring as essential good practices, offering these key steps:

Step 1: Use an observability platform

Leverage tools that automate testing, provide objective metrics, and offer actionable feedback on prompt configurations and outputs.

Observability platforms like Traceloop offer features like corner case testing, stress testing, and adversarial testing to identify vulnerabilities and unexpected behaviors. You can connect it with your development and deployment pipelines for seamless integration into your existing processes.

Step 2: Define success metrics 

Here’s a detailed list of metrics you should consider when starting with LLM observability:

• Latency: Basically, how fast the AI responds to a request. For anything that needs to work in real-time, like chatbots, faster is better. If you're juggling different AI models, comparing their speeds can help you pick the best one.

• Throughput: This tells you how many requests your AI can handle in a set amount of time. How many questions can it answer in a set time? If you're hitting the limits of what your AI can do, it might be time to ask for a higher limit or manage how much it's used better.

• Error Rate: Keep track of how often the AI gets things wrong. This helps you figure out how reliable it is and when you might need to step in to make improvements.

• Token Usage: Tokens are like the words and bits of words the AI juggles when it's thinking. Tracking this helps you manage costs, as more complex thoughts can mean higher bills.

• Response-Time-to-Prompt-Token Ratio - This one's a bit more technical, but think about the balance between how much your AI needs to "think" (how many tokens it uses) and how quickly it delivers an answer. Odd patterns here could hint at deeper issues, like if your prompts are too vague or too complicated.

Understanding these metrics can help you get the most out of your AI, ensuring it's fast, reliable, and cost-effective for your business needs.

Step 3: Gather Diverse Data 

Don't just use your existing data: Backtest and monitor your LLM on data representative of your target audience and use cases. Consider:

• Real-world data

• Diversity of demographics and viewpoints

• Edge cases that might challenge the LLM and expose potential biases or vulnerabilities

🏆 Golden Nuggets

• LLMs aren't magic solutions. They have limitations in factual accuracy, reasoning, and context-sensitivity.

• Don't use an LLM to evaluate another LLM's output. This creates a circular validation loop that perpetuates issues.

• Regularly backtest and monitor your LLM to adapt to changes in data, user behavior, and societal norms.

Secret Sauce of AI Success: Navigating the Complexities of LLM Deployment

OpenTelemetry is the secret ingredient that enables different parts of your model to report back on how they're doing in real time.

It is a set of tools, APIs, and SDKs that work together to collect, generate, and manage telemetry data (like metrics, logs, and traces) from software applications and services.

This classic engineering concept was wrapped and adapted for LLMs, calling it OpenLLMetry.

🏆 Why Leverage OpenLLMetry for LLM Observability?

OpenLLMetry is a critical foundation part of your observability stack.

It's designed to easily integrate with a wide array of observability and analysis tools, so it can collect data on how your AI model perform in diverse environments, all in one place.

CAVEMINDS’ CURATION

What’s wrong with ChatGPT?

There’s a tricky issue with using ChatGPT and similar AI models: they're not great at checking their own work.

This is because its main job is to predict and generate text that sounds believable based on what it's learned from a huge amount of data, not to judge the truthfulness or accuracy of its responses.

Why can't an LLM just check itself?

Well, for one, it’s not built for it. LLMs generate text based on patterns they see in data, not on hard facts. 

So, when it tries to confirm if its previous response was correct, it's essentially guessing again, not truly verifying. The way an AI model is trained doesn’t include self-check

Then there’s also the AI hallucination problem. If you ask it to verify something it made up, it might just double down, giving you a confident but incorrect validation.

What are some other challenges that you should avoid if you are building an LLM?

⚒️ Actionable Steps

Tip #1: Don’t Rely on ChatGPT for Everything 

Encourage your dev team to research beyond mainstream LLMs like ChatGPT. There's a whole universe of AI models out there that might better suit your specific needs or offer unique advantages.

Start with a team brainstorming session to uncover and evaluate alternative LLMs that might offer distinct advantages for your projects.

Tip #2: Consider Open Source and Alternative Providers

Investigate open-source LLMs and other lesser-known models (Nir suggests Cohere or Anthropic). These alternatives may offer models with different strengths, such as better handling of large token windows or specialized ranking models.

Consider allocating a budget for testing these models on small-scale projects to identify ones that best meet your needs. 

Tip #3: Experiment with Token Windows and Attention Capabilities

Don't assume larger token windows automatically mean better performance. Experiment with how different models manage extensive contexts and understand their limitations. This will help you craft prompts and structure data that enhances the effectiveness of the LLMs in your applications.

Test how different models manage large token windows to find the best fit for applications needing extensive context. Understand the limitations of each model's attention mechanism, especially for large inputs.
