why o'reilly
Six things that set O'Reilly apart
Everything your team needs to go from reading about a technology to shipping it.
The Owned Corpus
Books from O’Reilly and close to 200 publishers, 30,000+ hours of video, 5,000+ role-based courses — worldwide rights.
The Live Practitioner Programme
120–150 live courses a month with the people who wrote the books; 20–25 Superstreams a year.
Answers & AI
Cited responses with a named author, AI search, code explainers — answers you can actually verify.
Labs & Sandboxes
Browser-based, no setup: Python, Kubernetes, Docker, Java, Linux, SQL, and the major clouds.
Verifiable Skills
Five-level skill plans and Open Badges 2.0, plus Academies for AI, Security, Manager, Soft Skills and Data Literacy.
Enterprise Layer
SSO, SCIM, Insights, a dedicated CSM, quarterly business reviews, and Content & Insights APIs.
beyond free tutorials
Topics your team won't find on YouTube or a free blog
Written and taught by the practitioners defining the field right now — not summarized secondhand.
Agentic AI Engineering
Building production-ready AI agents — not toy demos.
Context Engineering with DSPy
The emerging discipline behind reliable, non-brittle LLM systems.
Harness Engineering for AI Agents
Making autonomous agents observable, governable and adaptive over time.
Building AI Agents with MCP
Hands-on with the protocol now powering the next wave of AI tooling.
Spec-Driven Development with Claude Code
Practitioner-led technique, not a vendor’s marketing page.
Agentic Reliability Engineering
SRE practice rebuilt for infrastructure that increasingly runs itself.
