Sometimes reality outpaces expectations in the most unexpected ways.
While global AI development seems increasingly fragmented, Sber just released Europe's largest open-source AI collection—full weights, code, and commercial rights included.
No API paywalls.
No usage restrictions.
Just four complete model families ready to run in your private infrastructure, fine-tuned on your data, serving your specific needs.

What makes this release remarkable isn't merely the technical prowess, but the quiet confidence behind sharing it openly when others are building walls. Find out more in the article from the developers.

GigaChat Ultra Preview: 702B-parameter MoE model (36B active per token) with 128K context window. Trained from scratch, it outperforms DeepSeek V3.1 on specialized benchmarks while maintaining faster inference than previous flagships. Enterprise-ready with offline fine-tuning for secure environments.
GitHub | HuggingFace | GitVerse

GigaChat Lightning offers the opposite balance: compact yet powerful MoE architecture running on your laptop. It competes with Qwen3-4B in quality, matches the speed of Qwen3-1.7B, yet is significantly smarter and larger in parameter count.
Lightning holds its own against the best open-source models in its class, outperforms comparable models on different tasks, and delivers ultra-fast inference—making it ideal for scenarios where Ultra would be overkill and speed is critical. Plus, it features stable expert routing and a welcome bonus: 256K context support.
GitHub | Hugging Face | GitVerse

Kandinsky 5.0 brings a significant step forward in open generative models. The flagship Video Pro matches Veo 3 in visual quality and outperforms Wan 2.2-A14B, while Video Lite and Image Lite offer fast, lightweight alternatives for real-time use cases. The suite is powered by K-VAE 1.0, a high-efficiency open-source visual encoder that enables strong compression and serves as a solid base for training generative models. This stack balances performance, scalability, and practicality—whether you're building video pipelines or experimenting with multimodal generation.
GitHub | GitVerse | Hugging Face | Technical report

Audio gets its upgrade too: GigaAM-v3 delivers speech recognition model with 50% lower WER than Whisper-large-v3, trained on 700k hours of audio with punctuation/normalization for spontaneous speech.
GitHub | HuggingFace | GitVerse

Every model can be deployed on-premises, fine-tuned on your data, and used commercially. It's not just about catching up – it's about building sovereign AI infrastructure that belongs to everyone who needs it.

Top 5 Mistakes to Avoid When Learning JavaScript 🧠

1️⃣ Not Understanding How JS Runs
Don’t treat JavaScript like other languages. Learn how the browser, JS engine, call stack, and event loop work.

2️⃣ Confusing var, let, and const
Using var everywhere is outdated. Know when to use let (reassignable) vs const (constant) and avoid var unless necessary.

3️⃣ Skipping DOM Manipulation
JavaScript powers the web. Practice selecting elements, handling events, and updating the DOM without libraries.

4️⃣ Ignoring Asynchronous Code
Avoid relying only on setTimeout or promises without understanding how async/await works. It’s crucial for API calls and smooth user experiences.

5️⃣ Not Building Real Projects
Don’t stick to tutorials. Create real things: to-do lists, weather apps, form validators, or mini games. That’s how skills grow.

Web Development Basics You Should Know 🌐💡

Understanding the foundations of web development is the first step toward building websites and web apps.

1️⃣ What is Web Development?
Web development is the process of creating websites and web applications. It includes everything from a basic HTML page to full-stack apps.
Types of Web Dev:
- Frontend: What users see (HTML, CSS, JavaScript)
- Backend: Server-side logic, databases (Node.js, Python, etc.)
- Full Stack: Both frontend + backend

2️⃣ How the Web Works
When you visit a website:
- The browser (client) sends a request via HTTP
- The server processes it and sends back a response (HTML, data)
- Your browser renders it on the screen
Example: Typing www.example.com sends a request → DNS resolves IP → Server sends back the HTML → Browser displays it

3️⃣ HTML (HyperText Markup Language)
Defines the structure of web pages.
<h1>Welcome</h1>
<p>This is my first website.</p>

*4️⃣ CSS (Cascading Style Sheets)*
Adds *style* to HTML: colors, layout, fonts.
h1 {
color: blue;
text-align: center;
}

*5️⃣ JavaScript (JS)*
Makes the website *interactive* (buttons, forms, animations).
<button onclick="alert('Hello!')">Click Me</button>

*6️⃣ Responsive Design*
Using *media queries* to make websites mobile-friendly.
@media (max-width: 600px) {
body {
font-size: 14px;
}
}

*7️⃣ DOM (Document Object Model)*
JS can interact with page content using the DOM.
document.getElementById("demo").innerText = "Changed!";

*8️⃣ Git & GitHub*
Version control to track changes and collaborate.
git init  
git add .
git commit -m "First commit"
git push

*9️⃣ API (Application Programming Interface)*
APIs let you pull or send data between your app and a server.
fetch('https://api.weatherapi.com')
.then(res => res.json())
.then(data => console.log(data));

🔟 Hosting Your Website
You can deploy websites using platforms like Vercel, Netlify, or GitHub Pages.

💡 Once you know these basics, you can move on to frameworks like React, backend tools like Node.js, and databases like MongoDB.

HTML Basics You Must Know 🧱🌐

HTML (HyperText Markup Language) is the foundation of every web page. It structures content like text, images, links, and forms.

1️⃣ Basic HTML Structure
<!DOCTYPE html>
<html>
<head>
<title>My First Page</title>
</head>
<body>
<h1>Hello World!</h1>
<p>This is a paragraph.</p>
</body>
</html>


Explanation:
<!DOCTYPE html> → Declares HTML5
<html> → Root element
<head> → Info about the page (title, meta)
<body> → Visible content

2️⃣ Headings and Paragraphs
<h1>Main Heading</h1>
<h2>Subheading</h2>
<p>This is a paragraph.</p>


3️⃣ Links and Images
<a href="https://google.com">Visit Google</a>  
<img src="image.jpg" alt="Image" width="200">


4️⃣ Lists
<ul>
<li>HTML</li>
<li>CSS</li>
</ul>

<ol>
<li>Step 1</li>
<li>Step 2</li>
</ol>


5️⃣ Tables
<table border="1">
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<tr>
<td>Alice</td>
<td>25</td>
</tr>
</table>


6️⃣ Forms
<form>
<input type="text" placeholder="Your name">
<input type="email" placeholder="Your email">
<button type="submit">Submit</button>
</form>


7️⃣ Div & Span
<div> → Block-level container
<span> → Inline container
<div style="background: lightgray;">Box</div>
<span style="color: red;">Text</span>


💡 Practice HTML in a live editor like CodePen or JSFiddle to see instant results!

CSS Basics You Should Know 🎨💻

CSS (Cascading Style Sheets) is used to style HTML elements — adding colors, spacing, layout, and more.

1️⃣ CSS Syntax
selector {
property: value;
}

Example:
h1 {
color: blue;
font-size: 32px;
}


2️⃣ How to Add CSS
Inline:
<p style="color: red;">Hello</p>

Internal (within HTML):
<style>
p { color: green; }
</style>

External (best practice):
<link rel="stylesheet" href="style.css">


3️⃣ Selectors
* → All elements
p → All <p> tags
.class → Elements with class
#id → Element with specific ID
#title { color: blue; }.red-text { color: red; }


4️⃣ Colors & Fonts
body {
background-color: #f2f2f2;
color: #333;
font-family: Arial, sans-serif;
}


5️⃣ Box Model
Every HTML element is a box:
content + padding + border + margin

6️⃣ Layout with Flexbox
 {
display: flex;
justify-content: space-between;
align-items: center;
}


7️⃣ Responsive Design
@media (max-width: 600px) {
body {
font-size: 14px;
}
}


8️⃣ Hover Effects
button:hover {
background-color: black;
color: white;
}


9️⃣ Common Properties
color – Text color
background-color – Background
margin & padding – Spacing
border – Border style
width / height – Size
text-align – Alignment

💡 Tip: Organize your styles using class names and external CSS files for better scalability.

JavaScript Basics You Should Know 🌐

JavaScript is a scripting language used to make websites interactive — handling user actions, animations, and dynamic content.

1️⃣ Variables & Data Types
Use let for reassignable variables, const for constants (avoid var due to scoping issues).
let name = "Alex";  
const age = 25;

Data Types: string, number, boolean, object, array, null, undefined.

2️⃣ Functions
Reusable blocks of code.
function greet(user) {
return `Hello, ${user}`;
}

Or use arrow functions for concise syntax:
const greet = (user) => `Hello, ${user}`;


3️⃣ Conditionals
if (age > 18) {
console.log("Adult");
} else {
console.log("Minor");
}


4️⃣ Loops
for (let i = 0; i < 5; i++) {
console.log(i);
}


5️⃣ Arrays & Objects
let fruits = ["apple", "banana"];
let person = { name: "John", age: 30 };


6️⃣ DOM Manipulation
document.getElementById("demo").textContent = "Updated!";


7️⃣ Event Listeners
button.addEventListener("click", () => alert("Clicked!"));


8️⃣ Fetch API (Async)
fetch("https://api.example.com").then(res => res.json()).then(data => console.log(data));


9️⃣ ES6 Features
let, const
⦁ Arrow functions
⦁ Template literals: Hello ${name}
⦁ Destructuring: const { name } = person;
⦁ Spread/rest operators: ...fruits

💡 Tip: Practice JS in browser console or use online editors like JSFiddle / CodePen.

JavaScript Advanced Concepts You Should Know 🔍💻

These concepts separate beginner JS from production-level code. Understanding them helps with async patterns, memory, and modular apps.

1️⃣ Closures
A function that "closes over" variables from its outer scope, maintaining access even after the outer function returns. Useful for data privacy and state management.
function outer() {
let count = 0;
return function inner() {
count++;
console.log(count);
};
}
const counter = outer();
counter(); // 1
counter(); // 2


2️⃣ Promises & Async/Await
Promises handle async operations; async/await makes them read like sync code. Essential for APIs, timers, and non-blocking I/O.
// Promise chain
fetch(url).then(res => res.json()).then(data => console.log(data)).catch(err => console.error(err));

// Async/Await (cleaner)
async function getData() {
try {
const res = await fetch(url);
const data = await res.json();
console.log(data);
} catch (err) {
console.error(err);
}
}


3️⃣ Hoisting
Declarations (var, function) are moved to the top of their scope during compilation, but initializations stay put. let/const are block-hoisted but in a "temporal dead zone."
console.log(x); // undefined (hoisted, but not initialized)
var x = 5;

console.log(y); // ReferenceError (temporal dead zone)
let y = 10;


4️⃣ The Event Loop
JS is single-threaded; the event loop processes the call stack, then microtasks (Promises), then macrotasks (setTimeout). Explains why async code doesn't block.

5️⃣ this Keyword
Dynamic binding: refers to the object calling the method. Changes with call site, new, or explicit binding.
const obj = {
name: "Sam",
greet() {
console.log(`Hi, I'm ${this.name}`);
},
};
obj.greet(); // "Hi, I'm Sam"

// In arrow function, this is lexical
const arrowGreet = () => console.log(this.name); // undefined in global


6️⃣ Spread & Rest Operators
Spread (...) expands iterables; rest collects arguments into arrays.
const nums = [1, 2, 3];
const more = [...nums, 4]; // [1, 2, 3, 4]

function sum(...args) {
return args.reduce((a, b) => a + b, 0);
}
sum(1, 2, 3); // 6


7️⃣ Destructuring
Extract values from arrays/objects into variables.
const person = { name: "John", age: 30 };
const { name, age } = person; // name = "John", age = 30

const arr = [1, 2, 3];
const [first, second] = arr; // first = 1, second = 2


8️⃣ Call, Apply, Bind
Explicitly set 'this' context. Call/apply invoke immediately; bind returns a new function.
function greet() {
console.log(`Hi, I'm ${this.name}`);
}
greet.call({ name: "Tom" }); // "Hi, I'm Tom"

const boundGreet = greet.bind({ name: "Alice" });
boundGreet(); // "Hi, I'm Alice"


9️⃣ IIFE (Immediately Invoked Function Expression)
Self-executing function to create private scope, avoiding globals.
(function() {
console.log("Runs immediately");
let privateVar = "hidden";
})();


🔟 Modules (import/export)
ES6 modules for code organization and dependency management.
// math.js
export const add = (a, b) => a + b;
export default function multiply(a, b) { return a * b; }

// main.js
import multiply, { add } from './math.js';
console.log(add(2, 3)); // 5


💡 Practice these in a Node.js REPL or browser console to see how they interact.
