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.

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.

✅ Excel Logical Functions 🧠📊

Logical functions make Excel smart by automating decisions based on conditions—perfect for data analysis and reports.

🔹 1. IF Statement
Checks a condition and returns different values based on TRUE/FALSE.
Syntax: =IF(condition, value_if_true, value_if_false)
✅ Example: =IF(A1>50, "Pass", "Fail")
Returns "Pass" if A1 > 50, else "Fail".

🔹 2. AND Function
TRUE only if all conditions are met.
Syntax: =AND(condition1, condition2,...)
✅ Example: =IF(AND(A1>=50, B1>=50), "Eligible", "Not Eligible")
Both A1 and B1 need to be 50+ for "Eligible".

🔹 3. OR Function
TRUE if any condition is met.
Syntax: =OR(condition1, condition2,...)
✅ Example: =IF(OR(A1="Yes", B1="Yes"), "Approved", "Denied")
"Approved" if either A1 or B1 is "Yes".

🔹 4. NOT Function
Flips TRUE to FALSE and vice versa.
Syntax: =NOT(condition)
✅ Example: =IF(NOT(A1=""), "Filled", "Empty")
"Filled" if A1 isn't blank.

💡 Combine Them:
=IF(AND(NOT(A1=""), B1>0), "Valid", "Invalid")

✅ Text Functions in Excel ✂️📄

Text functions help clean, extract, and format text data. Useful for cleaning names, splitting columns, or preparing reports.

1️⃣ LEFT, RIGHT, MID
⦁ LEFT(text, num_chars): Get characters from start
⦁ RIGHT(text, num_chars): Get characters from end
⦁ MID(text, start_num, num_chars): Extract middle part
Example:
=LEFT("Excel", 2) → Ex
=RIGHT("Excel", 2) → el
=MID("Excel", 2, 2) → xc

2️⃣ LEN
Returns number of characters in a string.
=LEN("Excel") → 5

3️⃣ FIND & SEARCH
Finds position of text.
⦁ FIND is case-sensitive
⦁ SEARCH is not
=FIND("x", "Excel") → 2
=SEARCH("X", "Excel") → 2

4️⃣ TRIM
Removes extra spaces.
=TRIM(" Excel ") → Excel

5️⃣ CONCAT & TEXTJOIN
⦁ CONCAT: Joins values
⦁ TEXTJOIN: Joins with a delimiter
=CONCAT(A1, B1) → No space
=TEXTJOIN(" ", TRUE, A1, B1) → Adds space

6️⃣ UPPER, LOWER, PROPER
⦁ =UPPER("excel") → EXCEL
⦁ =LOWER("EXCEL") → excel
⦁ =PROPER("hello world") → Hello World

7️⃣ SUBSTITUTE & REPLACE
⦁ SUBSTITUTE: Replace specific text
=SUBSTITUTE("2023-11-25", "-", "/") → 2023/11/25
⦁ REPLACE: Replace based on position
=REPLACE("Excel", 2, 2, "++") → E++el

8️⃣ VALUE & TEXT
⦁ VALUE("100") → Converts text to number

Returns current date and time.
Example: =NOW()

3️⃣ DATEDIF(start_date, end_date, unit)
Calculates the difference between two dates.
Example: =DATEDIF(A1, B1, "D") → Days between A1 and B1

4️⃣ DAY(), MONTH(), YEAR()
Extracts day, month, or year from a date.
Example: =DAY(A1), =MONTH(A1), =YEAR(A1)

5️⃣ TEXT(date, format)
Formats dates/times into readable text.
Example: =TEXT(A1, "dddd, mmm dd yyyy")

6️⃣ EDATE(start_date, months)
Adds months to a date.
Example: =EDATE(A1, 3) → 3 months later
