TTS by Kyutai. A 100M-parameter CPU text-to-speech model, re-hosted as a content-addressed κ-object for the Hologram serverless substrate so the Bonsai demo can speak its answers as it writes them — 100% in the browser, on the CPU, leaving the GPU to the mind.

This is the int8 ONNX decode graph (community export by KevinAHM) plus one voice (alba, Kyutai's default), run with onnxruntime-web 1.20.0 (WASM/SIMD). No account, no data leaves the device; warm after one visit.

What's here

Each file is gzipped and stored as a content-addressed block b/sha256_<hex>.gz; the manifest lists them. Every block is verified against its content address before it is decompressed (Law L5).

role	file	what it is
`flow_lm_main`	flow_lm_main_int8.onnx	the streaming flow-LM backbone (autoregressive latents)
`flow_lm_flow`	flow_lm_flow_int8.onnx	the stateless flow-matching step
`text_conditioner`	text_conditioner_int8.onnx	text → conditioning embeddings
`mimi_decoder`	mimi_decoder_int8.onnx	Mimi codec decoder → 24 kHz PCM
`tokenizer`	tokenizer.model	SentencePiece tokenizer
`bos_before_voice`	bos_before_voice.npy	BOS conditioning prefix
`bundle`	bundle.json	runtime metadata (state manifests, sample rate)
`voice`	voice.alba.bin	ONE voice state (PTVB1, single voice) — extracted from the 8-voice `voices.bin`

manifest.json (sha256 transport axis) + manifest.blake3.json + sha256-to-blake3.map.json (canonical BLAKE3 κ axis). Any static host can serve this — the bytes carry identity, not the host.

Payload

131.7 MB raw → 75.7 MB stored (gzip), 8 blocks. Decode graph only — the voice-cloning encoder is omitted (a non-goal). One voice ships; swapping the voice is a one-file re-mint.

Measured (browser, 2026-07-16)

Chrome / WASM-SIMD, 24-core desktop: first sound 332 ms on a short clause single-threaded (1.07× realtime); 313 ms and 1.39× with threads (cross-origin isolation). Real speech, 24 kHz. Running concurrently with Bonsai-8B on WebGPU costs ~20% of decode throughput (CPU-orchestration, not GPU contention) — still real-time.

ONNX export: KevinAHM/pocket-tts-onnx (export scripts Apache-2.0); upstream Pocket TTS code is MIT.
Runtime worker: adapted from the KevinAHM/pocket-tts-web demo space.
