Pocket TTS is a lightweight (~100M param) continuous-latent autoregressive TTS model from Kyutai, based on the CALM paper (arXiv:2509.06926). Unlike codebook-based TTS models, Pocket TTS emits continuous float vectors — no discrete tokens, no softmax sampling: - **FlowLM backbone** — causal transformer (1024D, 16 heads, 6 layers; 24 layers for the French preview, RoPE, GELU) operating at 12.5 Hz - **Consistency head** — SimpleMLPAdaLN (512D, 6 ResBlocks) with timestep embedding → one-step LSD decode → 32-dim continuous latent vectors - **Mimi VAE decoder** — SEANet upsample convolutions + 2-layer transformer → 24 kHz PCM - **Mimi VAE encoder** *(voice-cloning builds only)* — SEANet downsample + 2-layer transformer + speaker projection → reference conditioning - **Text tokenizer** — SentencePiece BPE (4000 vocab, embedded in GGUF) Single GGUF file — no separate codec companion needed (Mimi weights and the tokenizer are embedded). Pocket TTS is zero-shot: it clones the timbre of a short reference clip. The **voice-cloning builds** (the files *without* `novc` in the name) embed the Mimi VAE **encoder** and speaker projection needed to condition on a reference; the English-only `novc` builds omit that encoder and are ~20 MB smaller.

GGUF / ggml conversions of `Qwen/Qwen3-ASR-0.6B` for use with the `qwen3-asr-main` CLI from **CrispStrobe/CrispASR**. This is the **first speech-LLM** in the CrispASR family — every other model in the set uses a dedicated CTC / transducer / encoder-decoder. The Qwen3-ASR runtime ships with a persistent KV cache so per-token decode is O(1) in cache size, not O(N) full re-forwards. All quantisations produce the correct transcript on `samples/jfk.wav`: > And so, my fellow Americans, ask not what your country can do for you; ask what you can do for your country.

Qwen3-ASR-1.7B is a multilingual speech recognition model supporting 30 languages + 22 Chinese dialects, with support for speech, singing voice, and songs with background music. Audio inputs up to 5 minutes. `qwen3-asr-1.7b-q4_k.gguf` was re-baked with the 24-layer **audio encoder kept at Q8_0** (previously Q4_K like the LLM body; ~0.15 GB larger). The earlier Q4_K export could emit an **empty transcript** (or, on longer audio, a repeated phrase) while still reporting success (CrispASR #240) — the same sub-8-bit encoder drift diagnosed in #218. Encoder-output cosine vs the F16 reference (jfk): **0.9632 → 0.9989** min, **0.9913 → 0.9998** mean — i.e. the tower is back to near-lossless and decode no longer degenerates. The Q8_0 and F16 files were never affected. On JFK speech sample (11s, English): - Q4_K: 0.2x realtime on CPU (4 threads) - Perfect transcription accuracy

GGUF conversions of `Qwen/Qwen3-ForcedAligner-0.6B` — a single-pass forced aligner that takes any (audio, transcript) pair and predicts per-word/per-token timestamps. Reuses the Qwen3-ASR audio encoder + 28-layer LLM body but swaps the lm_head from `(vocab, d)` to `(5000, d)`: each ` ` placeholder you embed in the input gets a 5000-class softmax over `class * 80 ms` timestamps. Plug it into CrispASR via `-am qwen3-forced-aligner-*.gguf` to get word-level timing on **any** transcription backend — voxtral, voxtral4b, qwen3-asr, granite, parakeet, canary, cohere, even whisper. It's an alternative to the existing `canary-ctc-aligner` second-pass with broader language coverage and 80-ms resolution. The CrispASR C++ runtime auto-detects which variant a loaded GGUF is by reading the lm_head shape from `output.weight.ne[1]` — no separate backend, no separate library.

GGUF / ggml conversion of `Qwen/Qwen3-TTS-12Hz-0.6B-CustomVoice` for use with **CrispStrobe/CrispASR**. The CustomVoice variant is the **fixed-speaker** sibling of `Qwen3-TTS-12Hz-0.6B-Base`: instead of cloning a voice from a 3 s reference WAV (the Base path), it ships **9 baked speaker tokens** picked via a `--voice ` flag. No ECAPA forward, no codec encoder, no reference audio required. Two of the speakers (`dylan`, `eric`) carry Chinese-dialect overrides (Beijing / Sichuan) that re-route `language_id` when synthesising Chinese-or-auto. Pair this with the codec at `cstr/qwen3-tts-tokenizer-12hz-GGUF` — the talker emits 16-codebook RVQ codes that the codec decoder renders to 24 kHz PCM.

GGUF / ggml conversion of `Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice` for use with **CrispStrobe/CrispASR**. The 1.7B sibling of `cstr/qwen3-tts-0.6b-customvoice-GGUF`. Same fixed-speaker pattern (9 baked speakers, no ECAPA, no reference WAV), but on the 1.7B talker — `hidden=2048`, `head_dim=128`, with a `small_to_mtp_projection` MLP that maps the 2048-d talker hidden state down to the 1024-d code predictor input space. Pair this with the codec at `cstr/qwen3-tts-tokenizer-12hz-GGUF` — the talker emits 16-codebook RVQ codes that the codec decoder renders to 24 kHz PCM.

MODEL HANDBOOK

Understand before you choose

Selection guide & FAQ
How should API prices be compared?+

Separate input, output and cache rates, then estimate the same workload. Image, audio and video rates may use items, duration or resolution rather than tokens.

Do open weights mean free commercial use?+

Not necessarily. Check each version’s license, commercial restrictions and policies. Self-hosting also incurs compute and maintenance costs.

Is the top-ranked model the best for me?+

Rankings depend on tasks, versions and methods. Compare accuracy, latency, reliability and costs on your own workload.
