TensorBench - API: leaderboard
TensorBench (2026) tests coding agents (a published CLI harness with its model) on feature-addition and refactoring tasks in Scorch, a compiler-based tensor framework with dense and sparse tensors; a task passes when the patched repository passes its randomized regression tests and the tests the agent adds. This board is the pass rate in percent on the 99 user-facing API tasks, such as linear algebra, constructors, shape operations and ML primitives; higher is better.
Metric: Pass rate (%) on the 99 user-facing API tasks (linear algebra, constructors and I/O, shape and layout, elementwise math, ML primitives and more); each coding agent (a published CLI scaffold with its model) edits the open-source Scorch compiler-based tensor framework inside a per-task container, one run per task; a task passes when every test of the post-patch suite (pre-existing randomized regression tests plus the tests the agent adds) succeeds; higher is better.
