Hwang et al.: fully shared depth decoding for memory-efficient speech synthesis

What changed

Separated temporal and codec-depth processing and reused a fully shared, stage-conditioned depth decoder across quantization levels, combining it with a fixed-window cache for streaming semantic-to-audio detokenization.

Scientific scope

Separated temporal and codec-depth processing and reused a fully shared, stage-conditioned depth decoder across quantization levels, combining it with a fixed-window cache for streaming semantic-to-audio detokenization. Moshi's temporal/depth factorization and DiT-style conditioning are inherited. Delta removes per-codebook projections, not invention of depth decoding. Constant memory concerns the fixed-window synthesis component, not total assets, output storage or the entire assistant. AMX latency/memory and deployment are source-reported.
