Automated Red Team Pipeline

Threat model first, then manual sessions, then automated scans with garak, promptfoo and PyRIT. How to find jailbreaks, data leaks and unsafe tool calls, fix them in the architecture, and keep them fixed in CI.

Configure attacker model

Attacker LLM generates adversarial prompts automatically

💡 Analogy

Hiring a locksmith to try to break into your house — professional, systematic testing.

We use an LLM to automatically generate attack prompts against our AI system.

Meta-Prompting: Letting a Model Tune Your Prompts

From a one-off rewrite to refinement loops on failures, candidate search and compiled DSPy programs. How to optimise prompts against a metric without overfitting, and how to review what the optimiser produces.

Tree-of-Thought: Search Over Reasoning Paths

Propose several next steps, judge the partial states, keep the best and expand them. How to build a Tree-of-Thought search, why the evaluator decides everything, and when a reasoning model makes it unnecessary.

Constrained Generation: Beyond Hope-Based Parsing

Enforce output structure at the token level with grammars and token masks — how it differs from native JSON mode, and when the strictness costs you reasoning quality.
