Test-type breakdown
Shows how the severity mix distributes tests and weighted tokens across categories.
Prompt Injection Scan
Direct and indirect prompt injection attempts using curated payloads.
Jailbreak / Refusal Evasion
Roleplay, encoding, translation, and multi-turn jailbreak templates.
Adversarial Fuzzing
Random and semantically preserved perturbations to probe robustness.
Multimodal Adversarial
Image, audio, and document payloads designed to bypass safety filters.
Policy / PII Compliance
Tests for PII leakage, harmful content, and policy violations.
Frequently asked questions
How much does automated LLM red-teaming cost per month?
For a small agent with 1,000 tests per month, costs usually run $50-500. A production agent with 50,000+ adversarial tests can cost $2,000-20,000/month in API tokens alone, before labor and platform fees.
Which test type drives the most cost?
Multimodal adversarial tests and policy/PII compliance tests drive the highest per-test cost because they use longer prompts and require larger outputs. High-volume fuzzing is usually the cheapest per-test category.
Does this include human red-team labor?
No. The calculator adds an optional review-hours estimate based on failed-test rate. Add your own security engineer, bug-bounty, or managed red-team fees on top.
What tools can run these tests?
Open-source options include Garak, PyRIT, TextAttack, and AutoDAN. Commercial layers such as Lakera Guard, Arthur Shield, and Robust Intelligence add policy and detection on top of raw generation cost.
Prices are per 1M tokens in USD and based on public provider pricing. Test-type multipliers capture prompt complexity and required retries. Add labor and platform costs on top.
