osobhandClaude Opus 4.7 a5cedfb46a rtx-csm: emotional_speech_guide — CREMA-D vs RAVDESS firdhokk verdict
8-gen bench (4 emotions × 2 corpora) at seed=42 against firdhokk
Whisper-LV3:

  target    RAVDESS              CREMA-D
  happy     happy (0.999) ✓      happy (0.999) ✓
  angry     neutral (0.92)       sad (0.99)
  fearful   happy (0.998)        fearful (0.984) ✓
  sad       angry (0.99)         fearful (0.99)

CREMA-D 2/4 vs RAVDESS 1/4. Larger / more naturalistic corpus
produces more class-pure fearful direction. Neither corpus solves
angry or sad — recipe shifts into 'vague expressivity' rather than
class-specific corners.

Practical: prefer CREMA-D when available; A/B both per emotion if
class precision matters.

//! CSM-1B safetensors → quantized GGUF converter.
//!
//! Builds the artifact a (future) forked `csm_quantized.rs` would consume.
//! For now: prints the policy decision report, writes the quantized GGUF.
//!
//! Usage:
//! ```
//! cargo run -p rtx-csm --release --example quantize -- \
//! --policy q8 --out /tmp/csm-q8.gguf
//! cargo run -p rtx-csm --release --example quantize -- \
//! --policy q4km --out /tmp/csm-q4km.gguf
//! ```
