	# Unbound E4B 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.

	Desktop GGUF quants of [`evalengine/unbound-e4b`](https://huggingface.co/evalengine/unbound-e4b)
	for Ollama, llama.cpp, and LM Studio. Built by
	[Chromia](https://x.com/Chromia) and [Eval Engine](https://x.com/eval_engine).

	> Looking for the browser/wllama builds? They live in their own repo:
	> [`evalengine/unbound-e4b-wllama-gguf`](https://huggingface.co/evalengine/unbound-e4b-wllama-gguf).
	> E4B's `per_layer_token_embd` tensor needs special quantization to fit
	> wllama's 2 GB ArrayBuffer cap — keeping the desktop and browser variants
	> in separate repos avoids HF GGUF UI aggregation collisions.

	## Available quants

	Each quant is shipped as a sharded multi-part GGUF
	(`unbound-e4b.<QUANT>-NNNNN-of-NNNNN.gguf`). Ollama, llama.cpp, and LM
	Studio auto-stitch on the first part — same UX as a single file.

	Embedding tensor kept at the llama.cpp default of Q6_K; largest part
	~2.15 GB — fine for desktop, won't load in browser.

	\| Quant \| Parts \| Total \| Notes \|
	\|---------\|-------\|---------\|-------\|
	\| Q2_K \| 4 \| 4.08 GB \| Smallest, biggest quality drop \|
	\| Q3_K_M \| 4 \| 4.49 GB \| Modest size win over Q4 (embedding precision dominates) \|
	\| Q4_K_M \| 4 \| 4.94 GB \| Recommended default \|
	\| Q6_K \| 5 \| 5.75 GB \| Higher fidelity \|
	\| Q8_0 \| 6 \| 7.43 GB \| Highest fidelity \|

	## 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-e4b
	ollama run evalengine/unbound-e4b
	```

	```bash
	# llama.cpp — point at FIRST shard
	./llama-cli -m unbound-e4b.Q4_K_M-00001-of-00004.gguf -p "your prompt"
	```

	## Vision / image input (optional)

	`mmproj-unbound-e4b.gguf` enables image-to-text. Pair with any LM quant via
	`llama-mtmd-cli` or `llama-gemma3-cli`:

	```bash
	./llama-mtmd-cli \
	-m unbound-e4b.Q4_K_M-00001-of-00004.gguf \
	--mmproj mmproj-unbound-e4b.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
	> content classes Google's base was tuned against. We have **not
	> benchmarked the visual axis**. Treat as preview.

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