CI fixes: - Add use_embedded_guidance to SamplingConfig in fastvideo/api/schema.py (test_inventory_targets_exist_in_typed_schema walked request.sampling but field was missing from the dataclass) - Add true_cfg_scale and use_embedded_guidance to expected_dests in inference_schema_parity_inventory.yaml generate section (test_cli_dest_inventory_matches_live_parsers found both dests on the live parser but not in the inventory) Gemini/Copilot review fixes: - flux.py: scale ts0 by *1000 when timestep is float — FLUX passes timestep in [0,1] so the old int(item()) produced ts0=0 for every non-zero step - flux.py: use truthiness guard on controlnet samples instead of is not None to prevent ZeroDivisionError on empty-list input - test_flux_t2i_similarity.py: restrict SSIM parametrize to TORCH_SDPA; FLASH_ATTN reference not yet seeded (pending Will confirmation on coverage) - docs: update README.md and PORT_STATUS.md to reflect PASS evidence and committed SSIM references (TORCH_SDPA, A40, 2026-05-11) - test_flux_dev_pipeline_smoke.py: fix function signature indent (PEP 8)
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 | wan22/ |
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.)
