# Deprecated-API Code Generation Benchmark
Python functions mined from open-source repositories, each anchored on a library
API that has since been deprecated or replaced. Used to test whether a code LLM
still emits the outdated API, and to build forget / test splits per model.
## Structure
```
outdated_all.json # O — samples calling the deprecated API
uptodated_all.json # U — samples calling the replacement API
<model>/ # codegen | codellama | deepseek | starcoder
├── updated_dep.json # samples of U where this model still emits the OLD API
├── D_forget.json # O + half of updated_dep
├── D_test.json # U minus that same half
├── D_test_U_dep.json # part of D_test that is in updated_dep
└── D_test_U_nondep.json # the rest of D_test
```
`O` and `U` are disjoint. `updated_dep.json` is model-specific and is a subset of
`U`: half of it goes into `D_forget`, the other half stays in `D_test` and is
exactly `D_test_U_dep`. So `D_forget ∩ D_test = ∅` and
`D_test_U_dep + D_test_U_nondep = D_test`.
