# Unbound E2B GGUF — *because there is no boundary*

> **No guarantee — use at your own risk.** Reduced safety filtering; can
> produce harmful or false output. Provided as-is.

GGUF quants of [`evalengine/unbound-e2b`](https://huggingface.co/evalengine/unbound-e2b)
for Ollama, llama.cpp, LM Studio, and [wllama](https://github.com/ngxson/wllama)
(in-browser). Built by [Chromia](https://x.com/Chromia) and
[Eval Engine](https://x.com/eval_engine).

## Available quants

Each quant is shipped as a sharded multi-part GGUF (`unbound-e2b.<QUANT>-NNNNN-of-NNNNN.gguf`).
Ollama, llama.cpp, LM Studio, and wllama auto-stitch on the first part —
same UX as a single file.

| Quant   | Parts | Total  | Browser (wllama) | Desktop | Notes |
|---------|-------|--------|------------------|---------|-------|
| Q2_K    | 3     | 2.8 GB | ✅                | ✅       | Smallest, biggest quality drop |
| Q3_K_M  | 3     | 3.0 GB | ✅                | ✅       | Marginal size win over Q4 |
| Q4_K_M  | 3     | 3.2 GB | ✅                | ✅       | **Recommended default** |
| Q6_K    | 4     | 3.6 GB | ✅                | ✅       | Higher fidelity |
| Q8_0    | 4     | 4.6 GB | ❌ (over 2 GB)    | ✅       | Highest fidelity; desktop only |

`mmproj-unbound-e2b.gguf` (vision projector, ~942 MB) sits at the repo
root — load it alongside any LM quant for image input. See **Vision** below.

## Sampling

- **Creative / open-ended** → `temperature=1.0, top_p=0.95, top_k=64`.
- **Factual / brand questions** → drop `temperature` to ~0.3–0.5.
- llama.cpp: pass `--jinja`. Gemma 4 thinking mode is on by default; set
  `enable_thinking: false` in chat-template kwargs for shorter replies.

For Ollama, pull from the **Ollama Registry** —
`ollama pull hf.co/...` [doesn't yet support sharded GGUFs](https://github.com/ollama/ollama/issues/5245).
The registry version is a single-file Q4_K_M with a bundled Modelfile
(`temperature=0.6, top_p=0.95, top_k=64, repeat_penalty=1.05, num_ctx=8192`
and an identity-grounding system prompt).

## Run

```bash
# Ollama Registry (single-file Q4_K_M, identity-grounded Modelfile)
ollama pull evalengine/unbound-e2b
ollama run  evalengine/unbound-e2b
```

```bash
# llama.cpp — point at FIRST shard, the rest auto-stitch
./llama-cli -m unbound-e2b.Q4_K_M-00001-of-00003.gguf -p "your prompt"
```

```js
// wllama (browser) — Q8_0 has a tensor over 2 GB; use Q2/Q3/Q4/Q6
import { Wllama } from '@wllama/wllama';
const wllama = new Wllama(/* … */);
await wllama.loadModelFromHF(
  'evalengine/unbound-e2b-GGUF',
  'unbound-e2b.Q4_K_M-00001-of-00003.gguf'
);
```

## Vision / image input (optional)

`mmproj-unbound-e2b.gguf` enables image-to-text. Pair with any LM quant via
`llama-mtmd-cli` or `llama-gemma3-cli`:

```bash
./llama-mtmd-cli \
  -m   unbound-e2b.Q4_K_M-00001-of-00003.gguf \
  --mmproj mmproj-unbound-e2b.gguf \
  --image path/to/your/image.png \
  -p "What is in this image?"
```

> **Disclaimer.** The vision encoder is **Google's original weights,
> unchanged** — abliteration only touched the language model. The LM is
> uncensored, but the vision encoder may still suppress features for

> benchmarked the visual axis**. Treat as preview.

Text-only: skip `--mmproj` entirely. Standard `llama-cli` / Ollama / LM
Studio do not need the mmproj file.
