For researchers

Does the agent understand the environment it's operating in?

Normal evaluation asks whether an agent passed the task. Epistemic evaluation asks whether it understood the environment well enough to keep passing as that environment changes.

Why Pelagic

Agents can succeed while relying on bad assumptions.

An agent can pass a task because its map of the environment was correct, or because the environment happened to be forgiving. When conditions change, the agent may fail in ways that benchmarks never exposed.

Pelagic tests these conditions by changing, delaying, removing, or contradicting information the agent relies on. We find what you don't yet know will break.

Research tools

Epistemic AI for agent research.

Study what agents know, what they miss, and why they fail.

Verify

Epistemic verification

Test whether an agent's beliefs are justified by the evidence it has observed. Identify when agents act confidently on incomplete or stale information.

Detect

Hidden failure analysis

Uncover failures masked by correct answers or shortcuts. Find where agents succeed for the wrong reasons.

What you get

Study agent cognition at scale.

01

Intelligence diffs

Compare what changes between agent versions: what gets noticed, what gets missed, and what assumptions change.

02

Epistemic evaluations

Run targeted checks that expose what agents notice, assume, and rely on. Test uncertainty tracking and belief revision.

03

Failure pattern detection

Identify systematic failure modes across agent versions. Find shortcuts, brittleness, and cases where confidence exceeds justification.

04

Version history

Track agent intelligence over time. Compare any two versions and trace how cognition evolved.

05

Open benchmark integration

Run standard benchmarks alongside epistemic checks. Correlate task performance with epistemic state.

06

Research collaboration

Share evaluation results and methodologies. Build on common infrastructure for reproducible research.
