BlueMagpie-TTS — GGUF

GGUF conversions of OpenFormosa/BlueMagpie-TTS, a Taiwanese-Mandarin text-to-speech model, for use with llama.rn and codec.cpp.

BlueMagpie is a continuous-latent autoregressive-diffusion TTS — VoxCPM2 with its Text-Semantic LM swapped from MiniCPM-4 to Barbet (Mamba2 + attention hybrid, 1B params). The AudioVAE decodes the continuous latent sequence to a 48 kHz waveform.

The BPE (GPT2-family) tokenizer is baked into every GGUF, so llama.cpp can tokenize text natively — no external tokenizer runtime needed.

Codec (AudioVAE + LM adaptor stack, runs in codec.cpp)

This bundle carries all continuous-latent codec_lm components the AR loop needs: tslm_adapter + FSQ + RALM (MiniCPM4-8L) + LocEnc + LocDiT (12L CFM diffusion) + enc_to_lm_proj + enc_to_tslm_proj + lm_to_dit_proj + res_to_dit_proj + AudioVAE decoder + stop head. codec.cpp probes codec_common codec_lm_get_info().is_continuous == true at load.

Runtime

The llama.rn side loads Barbet as the backbone context and this codec.gguf as the vocoder. getFormattedAudioCompletion returns flow = "continuous_embd" + embedding = true; the standard completion loop drives the codec_lm step machine per llama_decode, accumulating latent patches into result.embeddings, which decodeAudioEmbeddings turns into PCM at 48 kHz via the AudioVAE.

Requires llama.rn ≥ codec branch (adds LLM_ARCH_BARBET, the Mamba2/ attention hybrid graph builder, and the codec_common continuous-latent completion-loop hook).

Provenance

• Backbone converted via scripts/vendor/convert_barbet_to_gguf.py (llama.rn), which fuses the 5 Mamba2 in-projections + 3 conv1d into the ssm_in / ssm_conv1d tensors llama.cpp expects and bakes the GPT2 BPE tokenizer from the upstream tokenizer.json.
• Codec converted via scripts/convert-to-gguf.py --model-type bluemagpie (codec.cpp).
