## The POCKET lineup — pick by your device

| Repo | File | Size | Runs on | Best for | Korean PPL* |
|---|---|---|---|---|---|
| **POCKET-35B-GGUF** | `Q4_K_M` | 21 GB | PC / server (32 GB RAM) | top quality | **5.79** |
| **POCKET-35B-GGUF** | `Q2_K` ⭐ | 13 GB | mini-PC, no GPU | **daily driver** | 6.49 |
| **POCKET-35B-GGUF** | `IQ1_M` | 8.2 GB | 16 GB RAM box | smallest full model | 9.69 |
| **POCKET-KR-GGUF** | `IQ2_M` | 5.1 GB | Android 8 GB+ | 🇰🇷 Korean phone | 7.95 |
| **POCKET-KR-MLX** | 2-bit | 5.1 GB | 🍎 **iPhone / iPad / Mac** | 🇰🇷 Korean, Apple-native | 7.95 |
| **POCKET-EN-GGUF** | `iPhone-mix` | 5.3 GB | 🍎 iPhone (PocketPal) | 🌍 English phone | — |
| **POCKET-EN-GGUF** | `PC-mix` | 6.8 GB | PC / Android | 🌍 English, best quality | — |

*Wikipedia-Korean perplexity, lower is better. `Q4_K_M` = 5.79 baseline. English builds are tuned on English; see each repo.

> 🍎 **Why MLX for Korean but GGUF for English on iPhone?** Apple-native MLX only does uniform quantization. Korean survives it (96 experts hold up); English needs our proprietary quantization, which only GGUF supports — so the English iPhone build ships as a GGUF you run with [PocketPal](https://github.com/a-ghorbani/pocketpal-ai). Honest, not lazy.

> 🆕 **POCKET-26B** — a **Gemma4-26B-A4B**-based sibling that loads in **any app today** (Ollama · LM Studio · PocketPal · MLX), no bleeding-edge runtime needed: **[GGUF](https://huggingface.co/FINAL-Bench/POCKET-26B-GGUF)** (`Q2_K` 11 GB · `Q4_K_M` 17 GB · GPQA-Diamond **67%**). Universal compatibility for 12 GB phones, PC, and browser.

![Speed vs Bonsai](./pocket_speed.svg)

## Benchmarks — what is measured, what is not

**We measure Bonsai on the same machine with the same stock `llama.cpp`, and we tell you where we lose.**

`[measured]` Generation speed — POCKET wins on both CPU and GPU:

| | POCKET-35B IQ1_M | Bonsai-27B Q1_0 | |
|---|---|---|---|
| CPU generate (Xeon, 16t) | **27.0 tok/s** | 10.1 | 🟢 2.69× |
| GPU generate (H100) | **197 tok/s** | 89 | 🟢 2.22× |
| GPU prompt (H100) | 753 | **1816** | 🔴 0.41× |
| Quality (HellaSwag, 400q) | 61.0% | 60.0% | ⚪ tie (CI overlaps) |

`[measured on a MacBook M3 Pro, 18 GB]` — and on a laptop, POCKET wins **every** axis, including prompt processing:

| | POCKET-35B IQ1_M | Bonsai-27B Q1_0 | |
|---|---|---|---|
| Metal generate (tg64) | **25.4 tok/s** | 12.8 | 🟢 1.99× |
| CPU generate (8 threads) | **13.8 tok/s** | 4.4 | 🟢 3.13× |
| Metal prompt (pp128) | **240.7 tok/s** | 73.4 | 🟢 3.28× |
| CPU prompt (pp128) | **45.5 tok/s** | 9.6 | 🟢 4.75× |

On a laptop GPU the arithmetic headroom that let Bonsai win prefill on an H100 is gone, so MoE sparsity wins across the board. `POCKET-35B-Q2_K` runs on the M3 Pro's CPU at **19.5 tok/s** — on an 18 GB Mac, run Q2_K on CPU (`-ngl 0`); its 13 GB exceeds the recommended Metal budget.

`[measured — GPQA Diamond, 198q, greedy]` reasoning quality vs quantization:

| Model | GPQA-Diamond (greedy) |
|---|---|
| Qwen3.6-35B-A3B | 73.2% |
| POCKET-35B Q4_K_M | 68.7% |
| POCKET-35B Q2_K | 60.1% |

`[pending — community reports welcome]` on-device **iPhone** and **Strix Halo** throughput. We publish only what we ran ourselves; help us fill the rest.

> The same-size rival `Ternary-Bonsai-27B-Q2_0` (7.2 GB) **fails to load in upstream llama.cpp** — it needs the PrismML fork. POCKET runs on the tools you already have.

## Files in this repo
| Format | Size | Runs on |
|---|---|---|
| MLX 2-bit (`model-*.safetensors`) | 5.1 GB | 🍎 iPhone Pro / iPad / Mac |

Apple-silicon native (Metal). For Android/PC use the [GGUF build](https://huggingface.co/FINAL-Bench/POCKET-KR-GGUF).

## Quickstart (Mac)
```bash
pip install mlx-lm
mlx_lm.generate --model FINAL-Bench/POCKET-KR-MLX --prompt "안녕하세요"
```
On iPhone/iPad: [MLX Swift examples](https://github.com/ml-explore/mlx-swift-examples).

## Lineage — where POCKET comes from

POCKET is quantized from **[Darwin-36B-Opus](https://huggingface.co/FINAL-Bench/Darwin-36B-Opus)**, VIDRAFT's flagship — a model bred and evolved over several generations on the **Darwin platform** (crossbreeding, healing, expert surgery). Darwin-36B-Opus itself traces back to a Qwen3.5-family MoE architecture.

| Component | Origin |
|---|---|
| **Starting checkpoint** | **[Darwin-36B-Opus](https://huggingface.co/FINAL-Bench/Darwin-36B-Opus)** — VIDRAFT, multi-generation Darwin evolution |
| Base architecture | Qwen3.5-family MoE (256 experts, top-8), unchanged |
| Quantization (`Q4_K_M`…`IQ1_M`) | stock llama.cpp — no custom format |
| Runtime | upstream llama.cpp / Apple MLX — unmodified |
| Proprietary language-specific tuning (KR/EN builds) | **ours** (VIDRAFT) |

The CPU/GPU speed comes from the sparse-MoE architecture plus ordinary quantization — reproducible with the same base and the same tools. What we add is the Darwin-evolved weights, the honest measurement, the Korean tuning, and the pruning that makes the 5 GB phone builds.

## Limitations
- The iPhone/Mac speed is **not yet measured by us** — community reports welcome.
- Extreme quants (`IQ1_M`) hurt Korean ~2.8× more than English; use `Q2_K` or larger for quality.
- English phone builds trade quality for size; the PC build (`PC-mix`) is much closer to full quality.
