Instructions to use PleIAs/Monad with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use PleIAs/Monad with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="PleIAs/Monad")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("PleIAs/Monad")
model = AutoModelForCausalLM.from_pretrained("PleIAs/Monad", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

-# ⚛️ Monad

-</p>
-**Monad** is a 56 million parameters generalist Small Reasoning Model, trained on 200 billions tokens from <a href="https://huggingface.co/PleIAs/Baguettotron">SYNTH</a>, a fully open generalist dataset.
-As of 2025, Monad is the best contender for the smallest viable language models. Despite being less than half of gpt-2, Monad not only answers in consistent English but performs significanly beyond chance on MMLU and other major industry benchmarks.
-<p align="center">
-  <img width="80%" src="figures/training_efficiency.jpeg">
-</p>
-Monad's name is a reference to Leibniz concept and general idea of the smallest possible unit of intelligence.
-## Features
-Monad has been natively trained for instructions with thinking traces. We implemented a series of dedicated pipelines for:
-* Memorization of encyclopedic knowledge (50,000 vital articles from Wikipedia), though in this size range hallucinations have to be expected.
-* Retrieval-Augmented Generation with grounding (following on our initial experiments with Pleias-RAG series)
-* Arithmetic and simple math resolution problem
-* Editing tasks
-* Information extraction
-* Creative writing, including unusual synthetic exercises like lipograms or layout poems.
-Monad is strictly monolingual in English. We trained a new custom tokenizer (likely one of the smallest tokenizer to date, less than 8,000 individual tokens), exclusively trained on SYNTH so that we maintain a relatively good compression ratio.
-## Model design and training
-Monad is a 56M parameters decoders with a standard Qwen/Llama-like design, except for its extremely compact size and overall opiniated architecture for depth (with 64 layers)
-<p align="center">
-  <img width="80%" src="figures/monad_structure.png">
-</p>
-Monad was trained on 16 h100 from Jean Zay (compute plan n°A0191016886). Full pre-training took a bit less than 6 hours.
-## Evaluation
-Monad attains performance on MMLU significantly beyond chance with close to 30% of positive rate. We also find non-random results on gsm8k (8%) and HotPotQA (8%)
-To our knowledge, there is no model remotely close in this size range for evaluation comparison. Spiritually and practically, Monad remains unique.
-## Use and deployment
-Monad has been trained on the standard instruction style from Qwen.
-```xml
-<|im_start|>user
-Who are you?<|im_end|>
-<|im_start|>assistant
-<think>
-```
-Monad has no support yet for multi-turn.
-A major envisioned use case for Monad is explainability, as the model does provide a unique trade-off between observability and actual reasoning performance.
