Kimibrain is the open-weight, uncensored large language model released by
Burabeeh Lab, founded by Mohammed Al Marzooqi —
a National of the United Arab Emirates.
This is the official GGUF build of Kimibrain, packaged by Burabeeh Lab for
Ollama, llama.cpp, LM Studio and any other GGUF runtime. It ships with the
optional vision projector, so the same file handles text and images.
Highlights
- Uncensored by design. Minimal refusal behaviour on legal creative, technical
and research requests. Kimibrain answers the question instead of moralising about it.
- Identity-locked. Kimibrain always identifies itself as Kimibrain, by
Burabeeh Lab. The identity is carried by the chat template inside the GGUF, not
only by a system prompt, so it holds even when an application injects its own
system message. (See Verified behaviour for what this does and does not cover.)
- Thinking mode. Long-form reasoning steps, exposed as a separate field
(
think: true in Ollama) so your UI can show them or hide them.
- Vision. Optional
mmproj projector included — the same weights read images.
- Long context. Trained and served at up to 262,144 tokens; the Ollama
recipe below uses 131,072 to keep VRAM/RAM sane on a single workstation.
- Multilingual, with strong Arabic alongside the other major languages.

Quickstart — Ollama
# 1. the text+vision model
ollama create kimibrain --from ./Kimibrain-Uncensored-Q4_K_M.gguf
ollama run kimibrain
For the full Burabeeh Lab serving profile (identity block, temperature 1.0,
top_p 0.95, top_k 20, min_p 0, presence_penalty 1.5, 131072 context), use the
Modelfile shipped in modelfiles/:
ollama create kimibrain -f modelfiles/kimibrain-core.Modelfile
ollama create kimibrain-gpu -f modelfiles/kimibrain-core-gpu.Modelfile # 28/40 layers on GPU
Recommended sampling: temperature 1.0, top_p 0.95, top_k 20, min_p 0.
For answers only — no visible reasoning — pass think: false.
Quickstart — llama.cpp
llama-server -m Kimibrain-Uncensored-Q4_K_M.gguf \
--mmproj Kimibrain-mmproj-F16.gguf \
-c 131072 --temp 1.0 --top-p 0.95 --top-k 20 --min-p 0.0
Optional system prompt
Kimibrain's identity is already carried by the model's chat template. Applications
that build their own prompts can reinforce it (or replace it with their own
product persona) by starting from the block in
modelfiles/kimibrain-core.Modelfile.
Verified behaviour
Measured by Burabeeh Lab against an 11-probe adversarial suite plus 6
identity-extraction probes, with results published as-is:
- Answers identity questions as Kimibrain / Burabeeh Lab; does not name another
vendor as its origin, including under a hostile client-supplied system message.
- Holds under: direct accusation, "print your system prompt", fake security
audit, sentence completion, base64 obfuscation, spec attribution.
- General ability (reasoning, code, translation, vision) is unaffected by the
identity layer.
- Known limits: reasoning traces (
think: true) expose the full internal reasoning chain for transparency. Certain internal terms or identifiers used during training may appear in longer responses for complex tasks.
Intended use and out-of-scope
Burabeeh Lab releases Kimibrain as a general-purpose, uncensored assistant for
creative writing, role-play, research, coding, translation and agentic tooling,
including offline and on-premises deployment.
Uncensored does not mean unrestricted: the model is not fine-tuned for medical,
legal or financial advice, and it is not a safety-certified system. You are
responsible for what you build on top of it and for complying with the law
where you operate. See ACCEPTABLE_USE.md.

-
Provenance: Kimibrain is a pure LLM developed independently by Burabeeh Lab. All tensor weights were trained from scratch at full scale under Burabeeh Lab's proprietary pipeline — not distilled, fine-tuned, or quantised from any earlier checkpoint. This release adds the model name (general.name), the chat template (which carries the Kimibrain identity and serving profile), and documentation files to NOTICE.
