+
+**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.

+
+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)

+
+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.
