Build evidence-based safety evaluations that turn risks into reliable tests, findings, and deployment decisions
Distinguish model-level from application-level risks and prioritize tests using evidence from the intended use case.
Translate prioritized risks into safe and unsafe behavior requirements with acceptance thresholds tied to use-case risk.
Assemble diverse safety test cases while controlling contamination and maintaining label quality.
Select refusal, compliance, harmful-output, and attack-success metrics and check their basic statistical reliability.
Implement repeatable evaluation pipelines with versioning, result storage, grading, and change-control triggers.
Triage failures, document residual risk, and produce a go-or-no-go recommendation supported by evaluation findings.

Define safety evaluation, distinguish it from quality assessment, and connect testing, red teaming, benchmarking, risk prioritization, and deployment gates.
3 lessonsBuild diverse test datasets, choose reliable safety metrics and grading methods, use benchmarks within their limits, and design realistic adversarial tests without creating new harm.
5 lessonsRun an end-to-end evaluation, automate repeatable pipeline execution, and classify failures by severity, exploitability, and likely root cause to select remediation or controls.
3 lessonsEvaluate retrieval and tool use, turn failures into regression tests, compare results over time, and connect documented residual risk to deployment recommendations.
3 lessonsLLM safety evaluation determines whether a system is safe for its intended use, rather than merely producing high-quality outputs. This course develops a practical evaluation workflow spanning risk analysis, test design, datasets, metrics, grading, adversarial testing, and automated execution. You will finish with the skills to interpret failures, assess residual risk, and support deployment decisions with documented evidence.
The course covers risk scoping, test criteria, safety datasets, reliability-aware metrics, automated grading, HELM Safety and HarmBench benchmarking, adversarial testing, and repeatable evaluation pipelines. It also addresses failure triage, RAG and agent evaluation, regression testing, continuous evaluation, reporting, and deployment gates.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

Something to operate in every section.
Three findings from decades of learning research shaped how every Fenzo lesson is built.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.
Retrieval practiceRe-reading
Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
