// sa3-ggml-test.cpp: parity test CLI for the StableStep GGML SA3 modules.
|
||||
//
|
||||
// Runs GGML ports of the SA3 conditioning modules against golden vectors
|
||||
// dumped from the validated ONNX graphs (see tools/onnx-export/), and reports
|
||||
// cosine similarity + max abs diff per component.
|
||||
//
|
||||
// Usage:
|
||||
// sa3-ggml-test --models <dir-with-sa3-*.gguf> --goldens <dir-with-manifest.json>
|
||||
// [--component text_enc|seconds|same_enc|same_dec|dit|all]
|
||||
//
|
||||
// Components:
|
||||
// text_enc: sa3-text-enc-BF16.gguf, T5Gemma encoder + learned padding
|
||||
// substitution. Inputs input_ids [1,S] i64 + attention_mask [1,S]
|
||||
// u8, expected embeddings [1,S,768] f32.
|
||||
// seconds: sa3-dit-BF16.gguf (embedder tensors only), NumberConditioner
|
||||
// expo Fourier embedder. Input [1] f32, expected [1,768] f32.
|
||||
// same_enc: sa3-same-enc-F16.gguf, SAME-L encoder. Input audio
|
||||
// [1,2,524288] f32, expected latents [1,256,128] f32.
|
||||
// same_dec: sa3-same-dec-F16.gguf, SAME-L decoder. Input latents
|
||||
// [1,256,128] f32, expected audio [1,2,524288] f32.
|
||||
// dit: sa3-dit-BF16.gguf, DiffusionTransformer single forward. Inputs
|
||||
// x [1,256,T] f32, t [1] f32, cross_attn_cond [1,S,768] f32,
|
||||
// global_embed [1,768] f32, local_add_cond [1,257,T] f32,
|
