This 277-page PDF unlocks the secrets of Large Language Models.

Here's what's inside: 🧡 Image
Chapter 1 introduces the basics of pre-training.

This is the foundation of large language models, and common pre-training methods and model architectures will be discussed here. Image
Chapter 2 introduces generative models, which are the large language models we commonly refer to today.

After presenting the basic process of building these models, you explore how to scale up model training and handle long texts. Image

Stanford just made fine-tuning irrelevant with a single paper.

It’s called Agentic Context Engineering (ACE) and it proves you can make models smarter without touching a single weight.

Key takeaways (and get the 23 page PDF): Image
Stanford just released a 23 page paper on Agentic Context Enginnering to improve Agents. Key ideas:

1. ACE = Agentic Context Engineering: treat system prompts + agent memory as a living playbook. Image
2. Log agent trajectories; reflect to extract actionable bullets: strategies, tool schemas, failure modes.

3. Merge updates as append-only deltas with periodic semantic de-duplication to keep the playbook clean.

Agentic AI: A comprehensive survey of architectures, appications, and future directions (A 37 page PDF)

Here are the best parts: Image
1. The Dual-Paradigm Framework

The survey argues that Agentic AI research must be categorized to avoid conceptual retrofitting (applying old symbolic models to new systems).
2. Key Findings and Implications

Paradigm-Market Fit: The choice of architecture is strategic and dictated by domain constraints (e.g., symbolic for high-stakes, neural for complex data analysis). Image

RIP BI Dashboards.

Tools like Tableau and PowerBI are about to become extinct.

This is what's coming (and how to prepare): Image
I've never been a fan of Tableau and PowerBI.

Static dashboards don't answer dynamic business questions.

That's why a new breed of analytics is coming: AI Analytics. Image
AI + Data Science is the future:

AI tools like:

- LangChain
- LangGraph
- OpenAI API

Are being combined with:

- SQL Databases
- Machine Learning
- Prediction

And the results are exactly what businesses need: real-time predictive insights. Image
