⚠ 7 edge cases flagged for review
Ready for production deployment →AI agents are deployed without QA
Software has CI/CD. Machine learning has MLOps. But AI agents? They go straight from development to production with no reliability testing.
Agent Failures in Production
of AI agents encounter critical failures within their first week of production deployment due to untested edge cases.
Average Cost of Agent Errors
lost per enterprise annually from autonomous agent mistakes — hallucinations, tool misuse, and cascading failures.
Standardized Testing Tools
There is no gym, no staging environment, no QA pipeline purpose-built for AI agents. Teams ship and pray.
“You wouldn't deploy a web app without tests. Why deploy an AI agent without them?”
QA Testing built for the agentic era
Variant Labs builds gym environments that let you stress-test autonomous agents the same way you'd test any software before it ships.
Gym Environments
Sandboxed, realistic simulations where your agents can be tested against thousands of scenarios before touching production.
Deterministic Replays
Reproduce any failure. Run regression suites. Ensure that what broke yesterday stays fixed tomorrow.
Reliability Scoring
Quantifiable confidence metrics — know exactly how ready your agent is before you deploy it.
Safety Guardrails
Catch hallucinations, tool misuse, and dangerous behaviors before they reach your users.
Framework Agnostic
Works with LangChain, CrewAI, AutoGen, custom frameworks — bring your own agent, we provide the gym.
CI/CD Native
Plug directly into your deployment pipeline. No deploy without a passing reliability score.
