Map where models do well and where they slip.

teleon.dev/docs/frontier keeps a capability matrix across tasks and harnesses, runs public and custom benchmarks, and scans for cliffs: similar tasks where results drop sharply.

Merged-cell tables fall sharply next to simple tables, which marks a cliff worth fixing.

What it does

Capability matrix

Pass rates by task family and harness, kept current.

Public and custom

Public benchmarks sit beside your own holdouts.

Cliffs become fixes

A sharp drop between neighbours seeds a repair task.

The contract

A frontier cell names the task family, the harness, pass@k and calibration.

Full glossary

Jagged frontier: The uneven edge of what models do well: strong on some tasks, weak on close neighbours.
pass@k: The share of tasks solved at least once in k tries.
Holdout: Test data kept apart from training and tuning, so scores on it show real performance.
