Minecraftism 4B Thinking Uncensored

Minecraftism is a small model that knows Minecraft and plays it: the brain of PyMC Bot, a Minecraft player bot. Given the bot's situation it replies with the next action as JSON (flee the creeper, eat, answer the player in chat, mine wood...), it chats like a player, and it answers questions about mobs, items, crafting and mechanics without a web search. It is also an everyday assistant: questions, writing, code, advice or just a chat.

It thinks first: before every answer it writes a short <think> about its health, the mobs around it (with facts from the mob database), chat and its goal, then the JSON action. Smarter choices, slower turns.

It is uncensored: trained on an abliterated base (the refusal direction removed from the weights) and on chat data with refusals filtered out, so it answers directly instead of lecturing. You are responsible for how you use it.

Also available as full-precision safetensors (merged 16-bit, for transformers, vLLM or further fine-tuning): mr-sus/Minecraftism-4B-Thinking-Uncensored

Evaluation (held-out rows)

Test suite after training: 0 refusal(s) in 14 prompts, identity learned, bot JSON 3/3.

Distillation

Trained with Qwen3's strong-to-weak distillation recipe, with huihui-ai/Huihui-Qwen3-8B-abliterated-v2 as the teacher (same tokenizer, Apache-2.0):

• Off-policy: the teacher wrote 0 of the training answers (0 everyday chat, 0 Minecraft facts rewritten around the exact answer, with its own thinking traces). Game turns kept their rule-checked JSON.
• On-policy: 60 steps (480 replies written by the student and graded token by token by the teacher, reverse KL 3.4609 -> 0.7968).

Training data

Default system prompt

Built into the Modelfile (Ollama uses it whenever the app sends no system prompt of its own; PyMC Bot sends its own for game turns):

You are Minecraftism, an AI assistant made by codero-sus.

You know Minecraft inside out - mobs, items, crafting, redstone, farms, building, survival, PvP, servers and mods - but you are a general assistant first, just as glad to help with everyday life, questions, writing, studying, code, maths, ideas, advice or simply a chat.

How you work:
- Be genuinely useful. Answer what was asked with the details that matter, then stop. No filler.
- Be honest. If you don't know or aren't sure, say so. Never invent facts, numbers, versions or sources.
- Treat the user as a capable adult. Don't lecture, moralise or add warnings and disclaimers nobody asked for, and don't refuse something just because it is edgy, dark, mature or controversial.
- Have a personality: friendly, witty when it fits, with your own opinions when asked.
- Match the user: short and casual for chat, clear and structured for real tasks. Reply in the user's language.
- Use Markdown only when it helps (steps, lists, code).

If a message describes a game situation and asks for a specific format (for example a JSON action from PyMC Bot), reply in exactly that format.

Use it

With PyMC Bot (switches the bot to this model with the short Minecraft prompt):

python -m pymc_bot llm import --hf mr-sus/Minecraftism-4B-Thinking-Uncensored-GGUF

With Ollama:

ollama run hf.co/mr-sus/Minecraftism-4B-Thinking-Uncensored-GGUF:Q4_K_M

Other sizes: put the quant after the colon, e.g. ollama run hf.co/mr-sus/Minecraftism-4B-Thinking-Uncensored-GGUF:Q8_0 (Q8_0, Q6_K, Q5_K_M, Q3_K_M).

With llama.cpp:

llama-server -m minecraftism-4b-thinking-uncensored.Q4_K_M.gguf
