AI Evaluation & Safety
Lakera
Lakera builds inference-time security controls for large-language-model applications: prompt injection detection, sensitive data leakage prevention, jailbreak detection, and hallucination guardrails. The Lakera Guard API sits between the application and the model. The team also runs Gandalf, a public prompt-injection challenge that has produced one of the largest open datasets of adversarial prompts.
Why this matters in 2026
Lakera's Gandalf challenge produced over 30 million attempted jailbreaks and became the de-facto prompt-injection benchmark in security research. The dataset directly informed OWASP LLM01 (Prompt Injection) classification.
