# q-bonsai-27b — Bonsai-27B as a κ-object (the full 27B mind, streamed like a film)

**Created using [Bonsai](https://huggingface.co/prism-ml/Bonsai-27B-gguf) by Prism ML.**

This is [prism-ml/Bonsai-27B](https://huggingface.co/prism-ml/Bonsai-27B-gguf) — a 27-billion-parameter
hybrid-attention model (Qwen3.5 family: 16 full-attention + 48 gated-delta linear layers) moved
end-to-end into **binary {−1,+1} weights (1.125 true bits/weight, embeddings and LM head included)** —
re-laid as a **content-addressed κ-object** for the [Hologram](https://github.com/Hologram-Technologies)
serverless substrate. **No re-quantization anywhere**: the trained sign bits pass through byte-exact.

## What's here

| File | What it is |
|---|---|
| `q-bonsai-27b.v1.holo` | ONE Range-streamable file: boot-ordered BLAKE3-verified blocks + embedded tokenizer, lm_head packed early so a progressive reader serves the decode-critical path first. |
| `manifest.json` + `b/*.gz` | The same 803 blocks as loose content-addressed parts (sha256 transport axis) — the parallel-fetch fast path on CDN origins. |
| `manifest.blake3.json` + `sha256-to-blake3.map.json` | The canonical BLAKE3 (κ) axis. |
| `tokenizer.gguf` | The source GGUF header (tokenizer + arch), for serverless load. |

Every block is verified against its content address **before** it is decompressed or touches the
GPU. Any static file host serving these bytes is an equal origin — the bytes, not the host, carry
identity.

## Pins

- manifest κ: `did:holo:sha256:00beea03509a79f6567879f019c04bb15dda8721f6320f8295d9ea1dd9ba54af`
- root κ (tensor blocks): `sha256:a5f7b8ed89546306702547e1e47541572ef58…` (full value in manifest)

## Architecture (from the GGUF header)

64 blocks, d=5120, ff=17408, vocab 248320; `full_attention_interval=4` → 16 full-attention layers
(24 heads × 256, 4 KV heads, per-head q/k RMSNorm, gated output) + 48 linear layers (gated-delta
SSM: conv kernel 4, state 128, 16 groups, dt-rank 48, inner 6144); MRoPE sections [11,11,10,0],
rope base 1e7; 262K trained context.

## Provenance

Weights: Prism ML's Bonsai-27B (Apache-2.0) — see `LICENSE` and `NOTICE.txt`.
Conversion: `compile2bit.mjs q1` pass-through + `holo-kappa-pack.mjs` (Hologram Q substrate).
Format `q1`: blob = `[signs N·K/8 B][f32 scales N·K/128·4 B]` per tensor; the GEMV kernel
dequantizes inside the matmul. Browser engine support for the hybrid architecture is in
active development on the Hologram substrate; the 8B sibling
([HOLOGRAMTECH/q-bonsai-8b](https://huggingface.co/HOLOGRAMTECH/q-bonsai-8b)) runs live today.
