Every key that repository YAML configs, Python examples, the Dreamverse backend, and tests passed through pipeline.experimental has a typed GeneratorConfig field, so they use those fields instead: engine.attention, engine.compile.regional, pipeline.flow_shift, pipeline.embedded_cfg_scale, pipeline.dmd_denoising_steps, pipeline.components.lora_nickname, pipeline.minimax_h3, and pipeline.longcat. No repository config outside the tests uses pipeline.experimental any more. The flat FastVideoArgs keywords that each migrated YAML file and each basic_fasth3.py option set produces match the previous ones. The golden snapshots of the two Hunyuan scripts now record embedded_cfg_scale and flow_shift as floats (6.0 instead of 6), because the typed fields are floats. The guidance tensor is built as float32 either way. The golden case untyped_experimental_keys is renamed attention_precision_and_flow_shift with identical content, and keys_without_typed_fields covers keywords that still go to pipeline.experimental.

Local Tests
Local-only parity, smoke, and component tests for FastVideo model ports. They compare FastVideo against the official reference implementations and are skipped in CI; run them locally on a single GPU (or CPU where noted).
For the CI-backed test suite, see fastvideo/tests/.
Layout
Tests are organized by model family, one directory per port. Each family
directory follows the layout produced by the
add-model-prep skill:
tests/local_tests/<family>/
├── README.md # reference assets, setup, test inventory
├── __init__.py
└── test_<family>_<component>_*.py
Families
| Family | Workload | Dir |
|---|---|---|
| Flux2 | T2I | flux2/ |
| Hunyuan GameCraft | T2V / I2V | gamecraft/ |
| GEN3C | T2V | gen3c/ |
| Kandinsky-5 | T2V | kandinsky5/ |
| LTX-2 | T2V (+ audio) | ltx2/ |
| Stable Diffusion 3.5 | T2I | sd35/ |
| Stable Audio Open 1.0 | T2A | stable_audio/ |
Wan2.2 I2V record-schema checks live in the package dataset tests.
Running a family
pytest tests/local_tests/<family>/ -v -s
See each family's README.md for setup (clones, weights, env vars, gated
tokens) and the per-component parity coverage.
Adding a new family
Run the add-model-prep
skill from the FastVideo repo root. It scaffolds the family directory and
README.md and stages reference clones + weights. (In-progress ports may also
add a PORT_STATUS.md from the same skill template; remove it once the port
lands.)
