Balanced profile · OpenAI text-embedding-3-small · ASI = Agent Stability Index (0–100, higher is better)

AI agents are unpredictable.
No one is measuring this.

Every team building on LLMs is flying blind. The same prompt returns different answers. You ship it anyway because you have no way to quantify stability.

Same prompt, different answers

Your AI agent responds differently every time. Users notice. Trust erodes. You have no way to measure it.

📋

No standard for AI reliability

There is no ISO score, no SLA, no audit trail for how consistently your agent behaves. Procurement asks. You have nothing.

🇪🇺

Compliance is coming

The EU AI Act requires documentation of high-risk AI systems. SOC 2 auditors are asking about AI controls. 'We tested it manually' is not enough.

How it works

Go from zero to a certified stability score in under 10 minutes.

01

Connect your model

Paste your API key and model name. Works with OpenAI, Anthropic, and any provider with a standard chat API.

02

Run the benchmark

Stabilium runs your agent through 100+ curated cases across reasoning, coding, safety, and planning domains.

03

Get your ASI score + report

Receive a per-domain stability breakdown, a compliance-ready PDF, and a CI/CD badge you can gate deployments on.
