LLMs are the new operating system for work. πŸš€πŸ’»

But most people still don’t know the difference between RAG, Embeddings, and Hallucinations. πŸ€”πŸ§ 

Here’s the vocabulary cheat sheet everyone in AI should know πŸ“šβœ¨

These foundational LLM concepts every professional, creator, founder, and tech enthusiast should know πŸ‘©β€πŸ’ΌπŸ‘¨β€πŸ’»πŸŽ¨πŸš€

⚑️ Machine Learning Roadmap 2026: a large map for entering ML without fairy tales about "neural networks in a month" πŸ€–

A large Russian-language roadmap for machine learning: from the first import of numpy to LLM, RAG, fine-tuning, AI agents, and MLOps, and even Vue coding. πŸš€

Inside, there's a normal structure: what to learn, in what order, why it's needed, and what should be achieved in practice after each stage. 🧠

The roadmap is divided into 7 tracks: πŸ“Š

1. Foundation: Python, mathematics, statistics, tools πŸ—οΈ
2. Classic ML: scikit-learn, tabular data, metrics, validation πŸ“ˆ
3. Deep Learning: PyTorch, CNN, RNN, training loop 🧠
4. LLM and transformers: attention, KV-cache, RAG, LoRA, agents πŸ€–
5. Generative AI: images, videos, audio, multimodality 🎨
6. MLOps and production: Docker, Kubernetes, CI/CD, monitoring, serving βš™οΈ
7. Specialization: CV, NLP, RecSys, RL, Safety 🎯

The roadmap doesn't sell the illusion of "training a model - becoming an ML engineer". 🚫

In real work, a lot of time is spent on data, metrics, deployment, monitoring, reproducibility, and error analysis. Model is just part of the system. πŸ› οΈ

A good idea from the roadmap: LLM doesn't make a junior a senior. It accelerates someone who already understands the basics. Without the basics, a person just becomes an operator of Copilot, who can't explain why everything broke down. πŸ›‘

In terms of time, it's no fairy tale either: ⏳

1. 0-3 months: mathematics, classic ML πŸ“š
2. 3-6 months: Deep Learning and PyTorch πŸ”₯
3. 6-12 months: LLM, RAG, fine-tuning, AI agents πŸ€–
4. 12+ months: MLOps, production, scaling, specialization πŸš€

Here, seven large free courses on machine learning, mathematics, and Vue coding are also collected! πŸŽ“

If you've long wanted to enter ML systematically, rather than jumping between videos about ChatGPT, Stable Diffusion, and "top-10 libraries", this is a good guide. πŸ—ΊοΈ

Stop studying LLM from random articles and videos that only explain individual pieces of the puzzle.

πŸ“š LLM from Scratch β€” this is a practical course on PyTorch for those who want to understand the entire path of modern LLMs: from the first Transformer block to RLHF.

Instead of endless theory, here we gather a complete model training chain:

πŸ”Ή Pretraining β†’ Finetuning β†’ Alignment in one course
πŸ”Ή Transformer from scratch: positional embeddings, self-attention, multi-head attention, MLP, residual connections, LayerNorm, and full Transformer blocks
πŸ”Ή Own training loop without Trainer magic: tokenization, batches, cross-entropy, validation loss, text generation
πŸ”Ή Modern architecture improvements: RMSNorm, RoPE, SwiGLU, KV Cache, sliding-window attention, and streaming cache
πŸ”Ή Full section on alignment: SFT, reward models, PPO-style RLHF, and GRPO with an analysis of how it looks in the training loop in practice

πŸ”– How to Reduce the Cost of LLM Inference by up to 90%

If your AI agents are constantly sending the same context, consider using LMCache. πŸš€

This open-source system manages a KV cache, allowing you to reuse already computed representations instead of recalculating them for each request. 🧠

As a result:
⚑️ Up to 14x faster Time To First Token;
⚑️ Up to 4x faster decoding;
⚑️ Significant savings in GPU resources and inference costs. πŸ’°

πŸ πŸ€– Run Your Own LOCAL LLM (Beginner Friendly)

LLMs are cool, but running your own local one hits different 😎
No cloud. No API keys. No limits.

🧩 Step 1: Install Ollama
Install Ollama on your machine (works on Mac, Windows, Linux).

Once installed, open your terminal.

πŸš€ Step 2: Run a model
ollama run llama3.2

This command:
β€’ Downloads the model
β€’ Starts it locally
β€’ Lets you chat instantly πŸ’¬

If you see the prompt, your local LLM is running.

βš™οΈ Step 3: Do local inference (API style)
Ollama runs a local server on your machine.
curl http://127.0.0.1:11434/api/generate \
-H "Content-Type: application/json" \
-d '{
"model": "llama3.2",
"prompt": "Explain overfitting like I am 12",
"stream": false
}'

If you get a JSON response with text β†’ βœ… it works.

πŸ’‘ Why this is powerful
β€’ Works offline
β€’ Private by default
β€’ Perfect for learning, testing, and small apps

This is the easiest way to start with LLMs locally.
