AgentSim
Simulate your agent before you ship it
AgentSim runs your agent definition against a batch of simulated scenarios and reports the success rate and failure modes — a pre-release safety gate that catches bad behavior before real users do. It starts at $29/month.
AgentSim runs your agent definition against a batch of simulated scenarios and reports the success rate and failure modes - a pre-release safety gate that catches bad behavior before real users do.
What each run produces
- Starts at $29/month
- Simulated scenarios with success rate
- Pre-release safety gate
How are the simulated scenarios generated?
From your agent definition it builds a batch of realistic scenarios covering normal and edge cases, so you test behavior you would not think to prompt by hand.
What does the success-rate report show?
It reports pass or fail per scenario plus the failure modes that recur, so you fix the pattern rather than one-off odd outputs.
Is AgentSim a pre-release gate?
Yes. Run it before shipping an agent to production; a low success rate is a clear stop-ship signal no demo could give you.
How is it different from AgentGrade?
AgentSim tests the agent before release; AgentGrade scores outputs after you build. They cover different stages — simulate first, then evaluate in the field.
When you should write it yourself instead
AgentSim focuses on a single job: Simulate your agent before you ship it. It watches or grades agents, but a dashboard is not a kill switch. Keep a human accountable for what the agent actually does.
What you get
- Scenario generation
- Success rate
- Failure modes
- Pre-release gate
Questions about output quality
What does AgentSim do?
AgentSim runs your agent definition against a batch of simulated scenarios and reports the success rate and failure modes — a pre-release safety gate that catches bad behavior before real users meet the agent.
How much does AgentSim cost?
Plans start at $29/month (billed $290/year). Check the live tool for the current plan before running a pre-release gate.
Who is AgentSim for?
AgentSim is built for teams shipping or operating AI agents who need this exact job done: Simulate your agent before you ship it.
How are test scenarios created?
It generates a batch of realistic scenarios from your agent definition, including edge cases you might not prompt by hand.
What does the report tell me?
It shows pass or fail per scenario and the failure modes that repeat, so you fix the root pattern instead of isolated bad outputs.
Is AgentSim the same as AgentGrade?
No. AgentSim is a pre-release gate; AgentGrade scores live outputs after build. Use AgentSim to validate before ship, AgentGrade to track quality afterward.
When should you not use AgentSim?
Not a substitute for a professional security audit or a formal compliance assessment. Use it to catch obvious gaps before production; regulated systems still need expert review.
