ISA-Bench: benchmark of constrained instruction-set programming games for evaluating computational reasoning
Researchers published ISA-Bench (arXiv:2609.22878v1), a benchmark of programming games that exercise reasoning in constrained instruction-set architectures (ISAs). Each game includes a full execution stack (parser, VM, verifier) for automated evaluation; experiments show reasoning-focused models outperform code-specialized and general-purpose models on average, unfamiliar syntax is a frequent failure mode, iterative feedback helps but with varying gains across architectures, and the authors introduce a reasoning–execution gap (REG) analysis; the benchmark code is open-sourced.

- Each game includes a full execution stack (parser, VM, verifier) for automated evaluation; experiments show reasoning-focused models outperform code-specialized and general-purpose models on average, unfamiliar syntax is a frequent failure mode, iterative feedback helps but with varying gains across architectures, and the authors introduce a reasoning–execution gap (REG) analysis; the benchmark code is open-sourced.
- ISA-Bench targets underexplored computational reasoning in unfamiliar ISAs and provides tooling and analyses (including REG) that can reveal where models find strategies but fail to express correct programs, guiding future model and benchmark development.
