Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

generative-ai-for-beginners AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  • Azure OpenAI Service, OpenAI API, and Microsoft Foundry Models (GitHub Models is retiring end of July 2026)
  • Jupyter Notebooks for interactive learning
  • Dev Containers for consistent development environment

Repository Structure:

  • 21 numbered lesson directories (00-21) containing READMEs, code examples, and assignments
  • Multiple implementations: Python, TypeScript, and sometimes .NET examples
  • Translations directory with 40+ language versions
  • Centralized configuration via .env file (use .env.copy as template)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
