Large Language Models explained briefly
Here’s a summary and explanation of the key ideas from the video “Large Language Models explained briefly” (by Grant Sanderson / 3Blue1Brown) — along with why they matter and how to think about them:
🎯 What is a Large Language Model (LLM)?
-
At its core, an LLM is a function (a mathematical model) that given some text, tries to predict what word comes next. 3blue1brown.com+1
-
Instead of just picking a single “most likely” word, the model assigns a probability distribution over all possible next words. YTScribe+1
-
When you interact with a chatbot built on an LLM, you’re basically feeding it your prompt, it predicts words one after another to generate a response. 3blue1brown.com
Why this matters: It gives us a simple way to think about how the “intelligence” of such a model arises — by mastering the statistical patterns of language, to the extent that it can produce fluent, coherent responses.
🧠 How does the model learn?
-
Pre-training
-
The model is fed massive amounts of text (e.g., from the internet) and learns to predict the next word given the previous context. 3blue1brown.com+1
-
This is done by starting with many “parameters” (weights) initialised randomly, and then using a training algorithm (e.g., back-propagation) to adjust these parameters so that the model’s predictions align with the actual next word in many examples. 3blue1brown.com
-
Because the amounts of data and parameters are enormous (hundreds of billions of weights, trillions of tokens) the scale is huge. The video emphasizes how incredible the computational cost is. YTScribe+1
-
-
Fine-tuning / Reinforcement Learning with Human Feedback (RLHF)
-
After pre-training, if you want the model to behave like a helpful assistant (rather than just predict next‐word in arbitrary text), you train it further. Workers provide feedback, flag bad outputs, reward good ones. The model is adjusted accordingly. 3blue1brown.com+1
-
Why this matters: Understanding those two phases explains why LLMs can generate sensible responses—and also why they sometimes go off (because their training objective is “next‐word prediction”, not “always be correct” or “always be helpful”).
🔍 The architecture: Transformers & Attention
-
The video explains that modern LLMs use a model type called a transformer, which is capable of processing much of the input text at once, instead of strictly one word after another. 3blue1brown.com
-
Key concept: Attention — each word/token has a numeric embedding, and by using attention, tokens can “look at” other tokens in the context to refine their meaning (for example distinguishing “bank” meaning “river bank” vs “financial bank” depending on context). 3blue1brown.com
-
After many layers of alternating attention + feed-forward operations, you arrive at a final representation which is used to predict the next word. 3blue1brown.com
Why this matters: It provides the mechanism by which the model handles context (what came before) and generates fluent, context-aware text. Without attention, handling long contexts or nuanced meaning becomes much harder.
✅ Putting it all together: Why LLMs seem “smart”
-
Because the model has seen so much text, it’s learned a lot about how language is usually used — grammar, patterns of meaning, typical word sequences, associations, even some reasoning.
-
When you ask: “Explain how a car engine works,” the model doesn’t have a built-in “understanding” like a human expert, but it has internalised hugely many examples of explanations, so it can construct a plausible answer by predicting next words in a coherent way.
-
The video emphasises: even though the model is just doing “next‐word prediction”, the output looks like dialogue, reasoning, or explanation. Because it’s good at predicting—the patterns it learned embed a lot of structure of language and knowledge. 3blue1brown.com
⚠️ Limitations & important cautions
-
Just because the output looks smart doesn’t mean the model knows things in the human sense. It can hallucinate (make up plausible-looking but incorrect things) because the next‐word objective doesn’t guarantee truth.
-
The underlying architecture is complex and parameter heavy, and the “why” for a specific model output is hard to interpret (emergent behaviour). The video notes that you often can’t trace exactly why the model picked one word out of many. 3blue1brown.com+1
-
Bias, training-data issues, cost, computation, energy: all major concerns with scaling LLMs. While the video may not go deeply into all ethical issues, the broader literature (see Wikipedia) shows these are real. Wikipedia
🧭 Why watch/understand this video
-
It gives a clear, visual, intuitive explanation of what LLMs are and how they work — especially useful if you’re not deep in AI.
-
It demystifies the “magic” of things like ChatGPT or other chatbots: yes, there’s a lot of engineering, but at base it’s “predict next word given context”, scaled up massively.
-
It helps ground expectations: when you use an LLM, you understand what its strength is (fluent generation from pattern-learning) and what its weaknesses are (lack of guaranteed truth, reasoning limitations, interpretability).

UX IZAZOVI I AI
Kako veštačka inteligencija menja korisničko iskustvo (UX) — i zašto je to važno i za biznis u Srbiji
Uvod
Korisnici više ne prihvataju „dovoljno dobro“ iskustvo. Očekuju da sve bude personalizovano, brzo i intuitivno. Istovremeno, tehnologije poput veštačke inteligencije (AI) menjaju pravila igre u UX dizajnu — iskustvo više nije samo vizuelno, već i pametno.
U ovom tekstu istražujemo kako se UX i AI dopunjuju, koje konkretne promene donose digitalnim projektima, i zašto je ovo važno i za domaće biznise.
Zašto UX postaje strateška prednost
Dobar UX znači zadovoljnog korisnika, a zadovoljan korisnik znači rast. Prema istraživanjima, kompanije koje ulažu u UX u proseku imaju do 35% veći ROI u odnosu na konkurenciju.
UX nije samo „lep dizajn“ – to je način na koji korisnik postiže svoj cilj bez frustracije. Loše iskustvo vodi do napuštanja stranice, gubitka poverenja i slabije prodaje.
Kako AI menja UX
1. Personalizacija u realnom vremenu
AI analizira ponašanje korisnika, prepoznaje obrasce i automatski prilagođava sadržaj — od preporuka proizvoda do načina prikaza interfejsa.
2. Automatizacija dizajna i testiranja
AI alati mogu samostalno testirati UX elemente i predlagati poboljšanja. Analizom toplotnih mapa, AI otkriva gde korisnici najviše klikću — i automatski optimizuje raspored elemenata.
3. Predviđanje ponašanja korisnika
AI modeli mogu prepoznati kada korisnik verovatno odustaje od kupovine — i u tom trenutku aktivirati poruku, popust ili predlog.
4. Dostupnost i inkluzivnost
AI pomaže u stvaranju pristupačnijeg UX-a — od automatskih opisa slika za osobe sa oštećenjem vida, do glasovnih interfejsa i chatbot-asistenata.
Primene u praksi (i u Srbiji)
- Automatska analiza korisničkog toka — prepoznaj gde korisnik odustaje.
- Pametni chat-botovi za bolju korisničku podršku.
- UX-generatori koji pomažu u prototipovanju i predlozima dizajna.
- AI testiranje — simulacija stotina korisnika pre lansiranja.
Izazovi i etička pitanja
- Privatnost podataka: korisnici moraju znati kako se njihovi podaci koriste.
- Transparentnost: UX ne sme biti manipulativan – korisnici moraju razumeti kako AI donosi odluke.
- Ljudski faktor: AI može pomoći, ali UX dizajner ostaje ključan da bi iskustvo bilo empatično i smisleno.
Perspektiva za Srbiju i region
Lokalni korisnici imaju specifična očekivanja — jezik, brzinu, i navike korišćenja mobilnih uređaja. Zbog toga UX+AI kombinacija mora biti lokalizovana – dizajniran interfejs mora razumeti srpskog korisnika.
Prednost: Kada lokalni tim primeni globalne AI-UX principe, dobija ogromnu konkurentsku prednost – jer kombinuje lokalno razumevanje i tehnološku inovaciju.
Saveti za dizajnere i biznise
- Uradite mini UX audit – otkrijte gde korisnici najčešće napuštaju proces.
- Isprobajte AI alate (npr. Uizard, Framer AI, Figma plugins).
- Testirajte personalizaciju – promenite poruke i raspored na osnovu ponašanja korisnika.
- Merite rezultate – dužina boravka, CTR, konverzije.
- Uključite korisnike u proces – AI je pomoć, ali povratne informacije su nezamenjive.
Zaključak
UX i AI zajedno čine moćan tandem. Veštačka inteligencija može automatizovati analize, predlagati rešenja i personalizovati sadržaj, ali ljudska kreativnost i empatija ostaju srce svakog dobrog korisničkog iskustva.
U Srbiji se upravo sada otvara prostor da se ovi principi primene na lokalne projekte — bilo da ste dizajner, developer ili vlasnik biznisa.
💡 Ako želiš da unaprediš UX svog projekta kroz AI, napiši mi — možemo zajedno osmisliti prilagođenu strategiju.

The discrepancy in portfolio availability—none on a general freelance platform like Giig versus a detailed, specialized one on Allianceteam.dk—suggests a deliberate strategy for portfolio management. Stevo may utilize platforms like Giig primarily for broad lead generation and to highlight his competitive pricing, while directing more serious inquiries, especially those interested in his specialized capabilities such as exhibition stand design, to his own website. This allows him to control the narrative, showcase his deep expertise in a specific, high-value niche (exhibition design involves complex 3D visualization, spatial planning, and large-format graphic production), and potentially secure more lucrative projects that require such specialized skills. This approach highlights a sophisticated understanding of online presence and client acquisition, indicating that while he is a versatile generalist for broader tasks, his "Alliance Team" brand is built around demonstrable niche expertise.
6. Client Engagement and Feedback Analysis
An evaluation of available client feedback for Stevo Vuk Culajevic reveals a mixed landscape across various platforms. On Worksome, his profile indicates that he has "not received any reviews" and lists "0 jobs" completed on the platform.
Despite the limited public textual reviews on major freelance platforms, his company's homepage, Allianceteam.dk, features a direct testimonial from Susanne Odgaard, providing curated positive feedback.
For prospective clients, various channels are available for engagement. Contacting Stevo through Giig requires signing up as a customer on the platform, which may introduce a barrier to initial inquiry.
The noticeable absence of extensive public textual reviews or completed job listings on major freelance platforms like Worksome, combined with only a numerical rating on Giig, could be a point of consideration for new clients relying solely on these platforms. However, despite this, Stevo maintains a positive 4.5-star rating on Giig. More importantly, his extensive experience (over 20 years)
7. Strategic Positioning and Value Proposition
Stevo Vuk Culajevic's market position is defined by a unique blend of attributes that collectively form a compelling value proposition for clients in the graphic design landscape. He explicitly positions himself as "Danmarks billigste grafiker" (Denmark's cheapest graphic designer)
Crucially, this cost advantage is coupled with a strong promise of quality. Central to his value proposition is the assurance of "Dansk kvalitet" (Danish quality)
He offers a broad and versatile skill set, capable of handling a "wide range of graphic tasks"
Operating as a remote designer for the Danish market from Aarhus, he maintains local accessibility, evidenced by a Danish mobile number.
This unique blend of seemingly contradictory elements—low price, high quality, extensive experience, broad skills, niche specialization, and cross-border operation with local accessibility—creates a highly differentiated and sustainable competitive advantage. His strategic positioning is not merely about being the "cheapest"; it is about being the cheapest while simultaneously offering "Danish quality," backed by decades of experience, providing both general versatility and specialized expertise, and maintaining a local touchpoint despite an international operational base. Purely local Danish designers may struggle to match his price point, while generic offshore providers may lack the "Danish quality" assurance, local understanding, or direct accessibility. Stevo effectively bridges these gaps, appealing to a significant market segment that seeks optimal value. This multifaceted, hybrid model allows Stevo Vuk Culajevic to carve out a distinct niche in the competitive freelance graphic design market. His longevity in the industry, despite evolving market dynamics, suggests the robustness and effectiveness of this model. For clients, this represents a unique opportunity to access high-caliber design services at a significantly reduced cost, making professional graphic design more accessible for a wider range of businesses.
8. Conclusion and Recommendations
Summary of Findings
Stevo Vuk Culajevic is a highly experienced graphic designer with over two decades of professional experience, operating a unique hybrid business model. He functions as a freelance graphic designer for the Danish market from Aarhus, Denmark, while simultaneously serving as the CEO of Allianceteam DOO, a registered advertising agency based in Serbia. His primary value proposition is "Danish quality at a Serbian price," a claim substantiated by his significantly lower hourly rates (150-300 DKK) compared to other Danish freelancers, making cost-effectiveness a key differentiator. He possesses a broad and versatile skill set encompassing various graphic design disciplines, including Art Direction, Logo Design, and Web Design. Notably, his company's portfolio on Allianceteam.dk reveals a strong specialization and proven track record in complex exhibition stand design, demonstrating expertise in 3D visualization and large-format graphics.
