# Code Migration v1.1 leaderboard

external benchmark

> Every figure below is reproduced as its upstream source published it: nothing is modelled, estimated, interpolated or converted. `Unavailable` means no source published the value — it is never a zero. Each value carries its evidence state and the date it was observed.

Reimplementing working programs in another language using the Pi agent harness and revised hidden tests.

## Code Migration v1.1 ranking

No model in the catalog has a published Code Migration v1.1 score. The benchmark is defined by Code Migration v1.1, but the catalog carries no value for it yet. An absent value is shown as absent here rather than as a zero.

Rows are ordered by the value the source published, highest first. The source does not state whether a higher value is the better result, so this document does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
