Real world simulations

for AI agents

Simulate user interactions, find model failures,
and create data for evals & fine-tuning

How it works

From simulation to
improvement in three steps.

Step 1

Simulate

Create multi-turn, auto-generated scenarios that mirror real user journeys and adversarial attacks.
Step 2

Analyze

Run A/B tests and red-teaming to reveal failures and measure performance.
Step 3

Improve

Turn failures into curated evals and fine-tuning data that strengthen your models.
Benefits

What every run gives you.

Why Contact Centers Choose Collinear's Solution

Simulations that represent
real-world data

Labeled outputs from multi-turn simulations that reflect real user interactions, not just synthetic test cases.

Analyze
performance gaps

Concrete examples of where your model breaks: multi-turn conversations, adversarial attacks, and edge cases that manual testing misses

Curated Post-training
data

Curated, high-signal datasets generated directly from failures — ready for fine-tuning to strengthen your model.
Outcomes

Your AI will fail. That’s the point.

Collinear replaces brittle, manual testing with automated simulations
that generate eval and fine-tuning data.

Old Way

Manual testing

One-off prompts and spot checks
Limited coverage of real user journeys
Failures discovered after launch
Expensive human-labeled data
Collinear Way

FAQs

Get answers to
common questions

Do you support both open-source and closed models?

Yes. Collinear works with any model, whether you're using proprietary APIs, open weight models, or custom fine-tunes.

Do we need to share our model or training data with you?

No. Collinear evaluates outputs, not weights or training sets. You stay in control of your models and data at all times.

Can I bring my own safety policies or evaluation criteria?

Absolutely. You can use our built-in Judges and red-teaming libraries, or customize them with your own rules and risk categories.

How quickly can we see results?

Most teams see clear insights within days, especially with our guided trials and baseline safety assessments.

Can Collinear run on-prem or in a private cloud?

Yes. We support flexible deployment models, including VPC-hosted, air gapped, and fully on-premise setups to meet enterprise security requirements.
