Planium-4B

Planium-4B is a 4B fine-tune of Qwen3.5 specialized in automated planning and its standard notation, PDDL (Planning Domain Definition Language). It is built primarily for robotics and other control systems.

In its 4-bit quantized build, it is small enough to run on an ordinary PC or an embedded board such as an NVIDIA Jetson — no cloud API, nothing leaves your machine.

What it does

Classical planning in PDDL, largely limited to the :strips and :strips :typing fragments:

turning a plain-language request into PDDL — typically the :goal or the problem file for a given domain,
reading and explaining an existing domain, problem or plan,
reasoning about states, preconditions, effects and goals,
spotting what is wrong in a piece of PDDL,
calling tools: it is trained to work in an agentic loop and to emit tool calls, so it can drive a parser, a planner or a plan validator itself instead of only producing text.

Temporal planning, numeric fluents and the richer ADL constructs are much less well supported.

The fine-tuning also mitigates a failure mode of the base Qwen3.5 on these tasks: reasoning that never terminates, or that drags on far longer than the problem warrants without getting closer to an answer. Planium-4B keeps its reasoning short and commits to an answer.

Files

File	Description
`model.safetensors-0000*-of-00002.safetensors`	Full weights (bfloat16)
`gguf/model.gguf`	Quantized build for llama.cpp (Q4_K_M, ~2.8 GB)

Usage

llama.cpp

Download gguf/model.gguf and point llama-cli at it:

llama-cli -m /path/to/model.gguf

Or serve it over an OpenAI-compatible API:

llama-server -m /path/to/model.gguf --port 8080

Transformers

from transformers import AutoModelForImageTextToText, AutoTokenizer

model_id = "valentin0901/Planium-4B"
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForImageTextToText.from_pretrained(model_id, dtype="bfloat16", device_map="auto")

messages = [{"role": "user", "content": "Write a STRIPS blocksworld domain."}]
inputs = tok.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
out = model.generate(inputs, max_new_tokens=1024)
print(tok.decode(out[0][inputs.shape[-1]:], skip_special_tokens=True))

Built for NeuroPlan

Planium-4B is the model behind NeuroPlan, a neuro-symbolic planning system that bridges large language models and symbolic planners: it turns a request into PDDL, hands it to the planner and runs the resulting plan.
