♾️ New Microsoft cloud updates support Indonesia’s long-term AI goals ✏️ Indonesia’s push into AI-led growth is gaining momentum as more local organisations look for ways to build their own applications, update their systems, and strengthen data oversight. ✏️ The country now has broader access to cloud and AI tools after Microsoft expanded the services available in the Indonesia Central cloud region, which first went live six months ago. ✏️ The expansion gives businesses, public bodies, and developers more options to run AI workloads inside the country instead of overseas data centres. 🧠 AI Toolbox Daily | Best AI tools

Tired of AI that refuses to help? @UnboundGPT_bot doesn't lecture. It just works. ✓ Multiple models (GPT-4o, Gemini, DeepSeek)  ✓ Image generation & editing  ✓ Video creation  ✓ Persistent memory  ✓ Actually uncensored Free to try → @UnboundGPT_bot or https://ko2bot.com

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.

That’s where the right projects come in. Not toy datasets, but projects that demonstrate storytelling, problem-solving, and impact. Here are 4 killer projects that’ll make your portfolio stand out 👇 🔹 1. Exploratory Data Analysis (EDA) on Real-World Dataset Pick a messy dataset from Kaggle or public sources. Show your thought process. ✅ Clean data using Pandas ✅ Visualize trends with Seaborn/Matplotlib ✅ Share actionable insights with graphs and markdown Bonus: Turn it into a Jupyter Notebook with detailed storytelling 🔹 2. Predictive Modeling with ML Solve a real problem using machine learning. For example: ✅ Predict customer churn using Logistic Regression ✅ Predict housing prices with Random Forest or XGBoost ✅ Use scikit-learn for training + evaluation Bonus: Add SHAP or feature importance to explain predictions 🔹 3. SQL-Powered Business Dashboard Use real sales or ecommerce data to build a dashboard. ✅ Write complex SQL queries for KPIs ✅ Visualize with Power BI or Tableau ✅ Show trends: Revenue by Region, Product Performance, etc. Bonus: Add filters & slicers to make it interactive 🔹 4. End-to-End Data Science Pipeline Project Build a complete pipeline from scratch. ✅ Collect data via web scraping (e.g., IMDb, LinkedIn Jobs) ✅ Clean + Analyze + Model + Deploy ✅ Deploy with Streamlit/Flask + GitHub + Render Bonus: Add a blog post or LinkedIn write-up explaining your approach 🎯 One solid project > 10 certificates. Make it visible. Make it valuable. Share it confidently.

If you’re just starting out in Data Analytics, it’s super important to build the right habits early. Here’s a simple plan for beginners to grow both technical and problem-solving skills together: If You Just Started Learning Data Analytics, Focus on These 5 Baby Steps: 1. Don’t Just Watch Tutorials — Build Small Projects After learning a new tool (like SQL or Excel), create mini-projects: - Analyze your expenses - Explore a free dataset (like Netflix movies, COVID data) 2. Ask Business-Like Questions Early Whenever you see a dataset, practice asking: - What problem could this data solve? - Who would care about this insight? 3. Start a ‘Data Journal’ Every day, note down: - What you learned - One business question you could answer with data (Helps you build real-world thinking!) 4. Practice the Basics 100x Get very comfortable with: - SELECT, WHERE, GROUP BY (SQL) - Pivot tables and charts (Excel) - Basic cleaning (Power Query / Python pandas) _Mastering basics > learning 50 fancy functions._ 5. Learn to Communicate Early Explain your mini-projects like this: - What was the business goal? - What did you find? - What should someone do based on it? React with ❤️ for more ENJOY LEARNING 👍👍
