Claude's system prompts evolved through dozens of versions in 2024–2025, with each change revealing concrete lessons for production prompt engineering. Find all their system prompts here https://docs.claude.com/en/release-notes/system-prompts Let's read them and see what we can learn! This

Codex vs Claude Code

In 2025, Anthropic tightened Claude Code usage limits without prior notice, leaving Max tier users hitting unexpected caps. That abrupt shift highlights how quickly the AI coding assistant landscape can change, and why choosing the right tool matters more than ever. Your team's development velocity, code quality, and

Humans Last Exam LLM: A Comprehensive Evaluation

Top AI models that ace traditional benchmarks are stumbling badly on a new test called "Humanity's Last Exam," scoring a mere 25%. This dramatic performance gap reveals just how far we still are from achieving expert-level artificial intelligence, despite the impressive capabilities of today'

Code World Model: First Reactions to Meta's Release

Imagine an AI that doesn't just autocomplete your code but actually understands what happens when code runs. That's the revolutionary promise of Code World Models (CWMs) — a new breed of AI that bridges the gap between pattern-matching and true computational reasoning. While traditional code AI
