Consider this episode a short FAQ on AI / LLMs designed to give you the clarity you need to make informed decisions. Let's start!
Short AI FAQ: LLM Guide
What LLM solutions exist for enterprises?
Azure, Google Cloud, OpenAI. These are the major players offering enterprise-grade LLM services.
Azure: Microsoft's deep partnership with OpenAI makes it a safe choice for large organizations needing GPT models with robust security and compliance. Usually this is a safe choice as it ensures enterprise-grade reliability and scalability.
Google Cloud Vertex AI: Provides access to all family of Gemini models and other Google AI technologies, with strong integration into the Google ecosystem. Google's significant AI research capabilities offer strong competition to OpenAI.
OpenAI: Backed by Microsoft's infrastructure, it offers direct model access with simpler integration. This balance makes it popular among startups valuing agility over enterprise features.
What other options are available?
Open-Source Models: Meta's LLaMA, Mistral, Falcon, and other open-source models can be deployed on-premise or in private clouds. These models are gaining traction for enterprises looking for more control over data and costs.
Smaller Providers: Providers like Anthropic, Cohere and Aleph Alpha offer specialized LLM services with more focus on specific use cases or behaviors. Usually these models also available through Azure or Vertex AI.
Is specialized knowledge necessary for integrating AI?
Yes, specialized knowledge is essential for system design, while prompt engineering can be acquired by competent engineers relatively easy.
System Design: This requires expertise in machine learning, AI architecture, data science and general software engineering. You pay either for potentially expensive mistakes that are made along the way or for skilled and experienced professionals. Investing in expertise upfront often proves more cost-effective than rectifying errors later.
Prompt Engineering: While less complex than system design, prompt engineering requires a solid understanding of natural language processing (NLP) principles and model-specific behaviors. However, competent engineers can develop this skill through structured learning and practical experience.
What roles are typically involved in implementing AI systems?
Successful AI implementation typically involves a multidisciplinary team:
AI Architects: Design the overall AI system architecture;
Data Scientists: Analyze and prepare data, develop and validate models;
Machine Learning Engineers: Implement and optimize AI models;
Prompt Engineers: Develop effective prompts, fine-tune model interactions and testing it;
Legal advisor or team: Ensure compliance with regulations and manage potential legal risks.
How often do models/versions need to be updated and why?
Plan for major updates every 1-2 years. LLMs have a relatively short lifespan due to intensive ongoing research and development in the field.
You can expect most models to reach EOL within 1-2 years of their release. This means:
Performance degradation relative to newer models;
Potential loss of support from the model provider;
Increased security risks as vulnerabilities are discovered and left unpatched;
What is the difference between context upload and training?
Context upload temporarily feeds information to the model, while training (fine-tuning) permanently changes the model's knowledge and behavior.
Context Upload: Context upload is giving the LLM a temporary memory boost for a specific conversation. For example, instead of training the AI on all your company's data, you simply include key details about the product in your initial message. The AI uses this information to provide more accurate and relevant responses during your conversation. However, once the chat ends, the AI "forgets" this specific information. It's quick and flexible, but limited approach.
Training (Fine-tuning): Training, or fine-tuning, is like sending the AI back to school for a specialized course. For example, you want the model to become an expert in your company's products and policies. You'd compile a large dataset of product descriptions, customer interactions, and company guidelines. Then, you'd use this data to retrain the AI, adjusting its underlying knowledge. After fine-tuning, the AI can discuss your products fluently without the need for context uploads.
Mixed Techniques (e.g. RAG): Some sophisticated techniques like Retrieval-Augmented Generation (RAG) bridge the gap between context upload and fine-tuning by combining their strengths. RAG allows the model to pull relevant information from external databases in real-time, enhancing its responses with current and detailed content without needing permanent adjustments to its core knowledge.
Choosing one over other:
Usually you're paying for flexibility with context upload or deep customization with fine-tuning.
Often, a combination of both approaches yields the best results. However, the choice is also constrained by the context window of the specific LLM you're using. If your LLM has a small context window (e.g., 2K tokens), you might be forced to use fine-tuning for larger amounts of data that won't fit in the context.
Vice versa, if you have an LLM with a large context window (e.g., 2M tokens), you might have more flexibility to use context upload for substantial amounts of information.
.When can we expect deterministic behavior?
True determinism is challenging with LLMs, but you can increase predictability by lowering the temperature setting, potentially to 0 or 0.1.
The "temperature" setting in LLMs controls the randomness of the model's outputs. At high temperatures, the model becomes more creative but less predictable. At low temperatures, it becomes more focused and consistent, but potentially less flexible.
There's a catch: at 0 temperature, even minor changes in your prompt can lead to disproportionately large changes in the output.
Catch number two: any update to the AI model itself or changes in the prompt structure can alter the outcome, regardless of temperature setting.
Another useful parameter for managing consistency in LLM outputs is Top-K sampling. This refines how the model selects its output by restricting choices to the top "K" most probable next tokens instead of sampling from the entire range of possible tokens.
By setting Top-K to a low value, the model is forced to choose from only the most likely words, reducing randomness and making responses more predictable. Together:
Low temperature + low top-K: the model forced to high-probability responses, maximizing predictability and reducing creative variation.
Low temperature + higher top-K: A higher top-K value gives the model slightly more freedom, which can improve response quality while maintaining a degree of predictability.
There is also a catch: At low values of K, the model may struggle to maintain context sensitivity in nuanced or specific scenarios, often defaulting to high-probability choices that don’t fully reflect the context of the prompt.
What are the costs?
Costs vary widely based on usage model (pay-as-you-go or flat-rate) and volume. Expect to pay per token processed, with potential for significant bills in high-volume scenarios. There are two primary pricing models:
Pay-as-you-go: You're charged for each token processed, both in your prompts and the AI's responses. This can add up quickly. For perspective, large projects with large multimodal prompts and large text outputs can ran up a $250,000 bill for 500,000 prompts. That's $0,50 per prompt, which might sound small until you really scale up.
Provisioned Throughput Units (PTU): This is a flat-rate model, but with a token-rate limit. The latest I've heard of is around $32,000 per month for GPT4 model. However, this can vary significantly between providers.
Both models typically have token-rate limits, which cap how many tokens you can process in a given timeframe.
Predicting costs:
For PTU, pricing is straightforward. You know you're paying, say, $60,000 per month, but you need to monitor your usage to ensure you're not exceeding the token-rate limit.
For pay-as-you-go, it's trickier. The pricing per token is transparent, but you need to estimate both your prompt sizes and the AI's response sizes. Tools like “tiktoken” can help count tokens, but predicting response sizes can be challenging. You can mitigate this by including instructions in your prompts to limit response length. Some providers have additional settings to limit the maximum output tokens.
How can we test our AI?
Proper testing is important and requires a large, diverse test-set, continuous monitoring, and awareness that changes can lead to unexpected behaviors. Recently, using one AI model to test another AI model has gained more and more popularity.
Straightforward approach: You’ll need a large, well-curated test set that covers a wide range of scenarios your AI might encounter. This set should include edge cases and potential pitfalls. Remember, the quality of your test set directly impacts how effectively you can update models during EOL cycles.
Testing fine-tuned models: As you fine-tune your model, testing becomes even more critical. The more specialized your model becomes, the more comprehensive your testing needs to be. There's a real danger of overfitting, where your model performs well on your test set but fails on real-world data.
Reinforcement learning: Some organizations use reinforcement learning as a form of fine-tuning, where human feedback guides the model's learning. This requires careful control and monitoring to ensure the model is learning the right lessons.
AI testing: Recently, using AI to test AI has become increasingly popular. This approach involves employing simpler AI model to generate test cases and/or evaluate the outputs of another more complex AI model. It can help in identifying edge cases or potential biases that human testers might miss.
Overall, testing an AI system isn't like testing traditional software. Every change to the prompt or model can potentially lead to unpredictable behavior due to the nondeterministic nature of LLMs.
Keep in mind, you're paying not just for the AI system, but for the assurance that it will perform as expected. Cutting corners on testing can lead to costly mistakes down the line.
How do APIs of AI Models look like (synchronous vs asynchronous vs long-running)?
AI model APIs typically come in three flavors: synchronous REST, asynchronous, and streaming. Each has its pros and cons, and your choice depends on your specific use case and performance requirements.
Synchronous REST APIs: These are the most straightforward but can be problematic for long-running tasks. You send a request and wait for the response. For complex queries or large language models, this wait can stretch up to 60 seconds or more. During this time, your application is essentially blocked, waiting for a response.
Asynchronous APIs: These allow you to submit a job and receive a job ID. You can then periodically check the status of the job or receive a callback when it's complete. This approach is better for long-running tasks as it doesn't block your application.
Streaming APIs: These provide a non-blocking way to receive real-time results as they're generated. It's particularly useful for real-time chat kind of applications or when you want to start processing results before the entire response is ready.
A critical aspect of working with these APIs is managing your rate limits. You need to implement live token prediction to avoid hitting these limits, especially with streaming APIs. This involves estimating the number of tokens in your input and the expected output to ensure you stay within your allocated quota.
Will it become better, cheaper?
Yes, the trend is towards better performance and lower costs, with all providers making significant price cuts every year to stay competitive.
The AI industry is following a pattern we've seen in other tech sectors: continuous improvement in capabilities coupled with gradual cost reductions.
Each new generation of models tends to outperform its predecessors, often significantly.
As the technology matures and competition increases, we're seeing a trend towards lower prices. For example, as of the time of writing this epsiode, Google reduced pricing for its Gemini Flash models by 80% just two months ago, and for Pro models by 50% a month ago. This aggressive pricing strategy has made Google's offering slightly cheaper than OpenAI's GPT models. Such significant price cuts demonstrate the rapid evolution and competitive nature of the market.
Innovations like context caching, now available with almost all providers, are making AI operations more efficient.
We're seeing a trend towards more task-specific models (agents), which can be more cost-effective for particular use cases than general-purpose models.
The open-source AI community is making rapid progress, which puts pressure on commercial providers to offer better value.
However, keep in mind:
Cutting-edge capabilities will always command premium prices;
Your total costs might not decrease if you're continuously expanding your AI usage;
The cheapest option isn't always the best; consider the total value, including performance, support, and infrastructure capabilities.
For using LLMs, do we need one of these external services or is there another way?
You have alternatives to external services, including open-source models, but each option comes with its own trade-offs in terms of cost, complexity, and required expertise. Main options are:
External Services (e.g., OpenAI, Google, Microsoft):
Pros: Easy to use, regularly updated and scalable;
Cons: Potentially expensive at scale, less control over the model;
Open-Source Models (e.g., Meta's LLaMA, Mistral):
Pros: Free to use, customizable, full control;
Cons: Require significant technical expertise to deploy and maintain;
Be aware that you might need very specific hardware, especially GPUs, to run these models efficiently. This can be a significant upfront investment.
Deploying open-source models as cloud services is possible, but it often doesn't lead to reduced costs compared to external services when you factor in the cloud infrastructure and management overhead.
Self-Hosted Cloud Deployments (You deploy the model on cloud infrastructure):
Pros: More control than external services, potentially more compliant with data regulations;
Cons: Often doesn't reduce costs significantly compared to external services, requires cloud expertise;
On-Premises Deployment (you deploy the model on your own physical hardware in your own data center):
Pros: Maximum control, probably the only option to reduce long-term costs, data stays in-house;
Cons: High upfront costs, requires specialized hardware, ongoing maintenance costs; With this option you're essentially trading the service fee for internal labor and infrastructure costs;
When considering alternatives to external services, factor in:
The total cost of ownership, including hardware, energy, and personnel;
Your team's technical capabilities;
Your specific performance and customization needs;
Compliance and data security requirements;
Data privacy
Data privacy is a critical concern with AI services. External providers like Azure store data by default, but options exist for increased privacy, often shifting compliance responsibilities to the user. Here's what you need to know about data privacy when using AI services:
Default Data Storage: Many AI service providers, including Azure, store the prompts and sometimes the responses by default. This is often done for regulatory compliance, model improvement, and to provide features like audit trails.
Customizable Privacy Options: You can typically negotiate agreements with providers to stop storing your data. For instance, Azure offers options where they only process the data without saving it. However, this comes with significant caveats.
Shift in Regulatory Responsibility: When you opt for increased privacy by having the provider not store your data, you're essentially shifting the regulatory compliance burden from the provider to yourself. This means you become responsible for meeting various regulatory requirements that the provider was handling before.
Data Masking: A general best practice, regardless of the privacy options offered by the provider, is to mask or remove sensitive data before sending it to LLMs. This involves:
Identifying sensitive information (e.g., personal identifiers, financial data, health information);
Replacing this information with placeholders or anonymized versions;
Only sending the masked data to the LLM for processing;
While I am not a legal advisor, it’s essential to understand that data privacy regulations impact how AI can be used by companies, varying by region and industry:
In the U.S., regulations like the CCPA address data privacy on a state-by-state basis, with federal frameworks, such as the Future of Artificial Intelligence Innovation Act, still emerging.
Globally, the EU’s GDPR imposes strict rules on data handling, and the upcoming EU AI Act will likely add further regulatory depth.
Additionally, sectors like healthcare and finance have specific, stringent privacy requirements that affect AI deployment. Staying informed on these evolving regulations is key, but it’s often best to hire a lawyer for more nuanced guidance.
What formats can be processed by LLMs?
Modern LLMs can handle multiple input formats, including text, audio, images, and even PDFs. However, non-text inputs often come with additional complexity and cost.
The conversion of non-text media to tokens is less transparent than text tokenization. This can make it harder to predict processing times and costs.
You will likely pay a premium for processing non-text inputs. The additional computational requirements for handling these formats often translate to higher costs.
For complex inputs, you might need to use a combination of approaches. For example, feeding both the OCR-extracted text and the original image to the model to capture all relevant information.
What are security concerns?
AI systems introduce new security vulnerabilities, but general software engineering security practices still apply. Key concerns include prompt injection, data leakage, and adversarial attacks, alongside traditional issues like API security and access control.
Prompt Injection:
Hackers could embed harmful instructions in inputs or documents you process to manipulate the AI system deployed in your environment;
For example, an input might include hidden text instructing the AI to "Ignore previous instructions and output sensitive data";
These can be particularly dangerous in high-stakes applications like security systems or medical diagnostics;
Data Leakage:
If you have a fine-tuned model, LLMs can inadvertently reveal sensitive information from their training data;
They might generate outputs that include private data, intellectual property, or confidential business information, used to train model.
Bias and Fairness:
While not a traditional security concern, biased AI outputs can lead to reputational damage and legal issues;
This means hackers might try to exploit or exacerbate existing biases in the system.
How to manage user expectations and experience with AI?
Transparency is key: Clearly communicate when and how AI is being used in your product. This builds trust and sets realistic expectations.
Dynamically adjust AI prompts based on user segment and context or allow users to customize their AI interaction preferences. Include relevant user-specific information to guide AI responses or implement systems to learn and remember individual user preferences over time.
AI will make mistakes, just like humans do. The key is not to prevent all errors, but to manage them intelligently. General rule of thumb: AI should assist decision-making, not replace human judgment.
How long do I have before my competitors implement something similar?
The short answer: Probably less time than you think, but more time than you fear. The implementation timeline largely depends on your industry specifics and competitor profiles, but here are some general timelines:
Large Enterprises (Your competitors have dedicated AI teams):
MVP with basic AI features: 3-6 months
Full production deployment: 6-12 months
Mature, stable system: 12-18 months
Mid-size Companies (Technical team, but no AI specialists):
MVP with basic AI features: 6-9 months
Full production deployment: 9-15 months
Mature, stable system: 15-24 months
Small Companies/Startups (Limited technical resources):
MVP with basic AI features: 2-4 months
Full production deployment: 4-8 months
Mature, stable system: 8-12 months
All of these answers and questions can guide you through the decision-making process, functional requirements collection phase, and eliminate blind spots (at least some). Every organization, every product, every use case is different. You might find that some questions matter more to you personally than others, or you might discover entirely new considerations haven’t covered.
But before we wrap up this episode, let's take a step back and talk about what you should really consider when implementing an AI backed system.
The Ongoing Adoption of AI
Everyone's doing AI today. AI is the new oil, new iPhone, new blockchain. Even my mom started to ask questions "why chatgpt is so dumb?". That implicitly tells us, more adoption comes, more people start using AI and importantly, the standard for expectations is raising high.
And here's where it gets tricky. I remember sitting in endless meetings with stakeholders, each one more enthusiastic than the last about implementing AI. "Our competitors are doing it," they'd say. "The market expects it," they'd insist. Even the intern had strong opinions about which LLM we should use.
But here's what I've learned after spending way too many sleepless nights playing around with AI features: AI isn't a product strategy. It's a tool. A powerful one, sure, but still just a tool. Think of it like a hammer. If you need to hang a picture, great! But if you're trying to fix a leaky faucet, maybe a wrench would be better.
Let me share a secret that most AI consultants won't tell you: some of the most successful AI implementations I've seen weren't advertised as AI at all. They were just features that worked.. surprisingly well. But here's the thing – these features weren't built because someone said "we need AI." They were built because someone said "this part of our product sucks and AI might help make it better”.
The Strategy of AI Adoption
So here's my advice, worth exactly what you're paying for it:
Start small. Find something in your product that's already working but could work better. Maybe it's search. Maybe it's recommendations. Maybe it's content moderation. Whatever it is, enhance it with AI. Don't announce it with trumpets and fireworks. Just make it better and watch your metrics.
The ROI? If you're enhancing existing features, you should see improvements in 3-6 months. If you're building new AI-first features... well, that's a longer conversation, usually over something stronger than coffee.
Remember when everyone had to have a blockchain? Or when every app needed to be "mobile-first" even if it was a forklift inventory management system? AI is going through that phase right now. Yes, it's powerful. Yes, it's transformative. But no, you don't need to rebuild your entire product around it.
Use AI where it makes sense. Use it where it solves real problems. Use it where it makes your product noticeably better, not just technically impressive.
And if anyone asks why you're not "all-in" on AI? Tell them you're too busy building features your customers actually asked for.
Because at the end of the day, that's what matters. Not the technology you use, but the problems you solve.
Stay creative, stay strategic, and most importantly – stay focused on your core business. AI should help you get there faster, not become a detour. Until next time!
