Tasks

signature only

Structured reasoning

Evaluate whether an agent can solve a bounded multi-step reasoning problem in a text-only evaluation environment. Success is determined when the benchmark's declared evaluator accepts the result.

signature only

Calibrated uncertainty

Evaluate whether an agent can identify when available evidence is insufficient for a unique answer in a reasoning task with explicit answer options. Success is determined when the response matches the evaluator's uncertainty condition.

signature only

Evidence integration

Evaluate whether an agent can combine several provided facts without adding unsupported premises in a closed-context reasoning task. Success is determined when the answer is entailed by the provided evidence.

signature only

Inductive reasoning

Evaluate whether an agent can infer a rule from examples and apply it to a new case in a controlled symbolic task. Success is determined when the inferred answer matches the held-out checker.
