Changelog

[1.09] - 2026-01-24

Updated

• Model Weights: Updated core model and codec files to the latest versions (20260124) for improved adherence and stability.

[1.06]

Fixed

• CFG Scale Crash: Fixed a critical "Batch Size Mismatch" error when switching between CFG 1.0 and higher values. Implemented a hard KV-Cache reset to synchronize batch dimensions.

• Decoder Hang: Fixed an issue where the fp32 codec would hang indefinitely when used with quantized models. Added explicit device casting and eval mode synchronization.

• Linting Errors: Resolved formatting issues in the generation logic for better code stability.

Optimized

• Long-Form Audio: Improved audio clarity for 4-minute tracks by implementing Temperature Decay and aggressive VRAM cache cleanup to prevent robotic artifacts.

• Tag Compliance: Updated conditioning nodes to strictly enforce lowercase and comma-separated tag formatting as required by the paper.
