🚀 Create Your Own LLM from Scratch with create-llm

Building a Large Language Model (LLM) doesn’t have to be complicated.

With create-llm, you can scaffold a complete LLM training pipeline in seconds — just like create-react-app, but for AI models.

✨ What is create-llm?

create-llm is an open-source CLI tool that sets up everything you need to build, train, and evaluate your own custom LLM from scratch.

It’s built for:

  • AI enthusiasts exploring LLMs
  • Researchers building domain-specific models
  • Startups needing custom AI assistants
  • Developers who want to learn the internals of training LLMs

đź›  Features

  • Full Project Scaffolding — tokenizer, dataset prep, training scripts, evaluation.
  • Custom Dataset Support — train on your own text data.
  • Synthetic Data Integration — optional integration with SynthexAI for generating high-quality synthetic datasets.
  • Choice of Tokenizers — BPE, WordPiece, Unigram.
  • Trainer-ready Pipeline — powered by PyTorch.
## 📦 Installation


npx create-llm my-llm
cd my-llm


đźš‚ Training Your Model

1. Prepare your dataset

python data/prepare_dataset.py --input data/raw.txt --output data/processed.txt

2. Train your tokenizer

python tokenizer/train_tokenizer.py --input data/processed.txt --output tokenizer.json --vocab-size 32000 --type bpe

3. Train your LLM

python train.py --config configs/train_config.json

🔥 Why SynthexAI?
We also built SynthexAI — a synthetic data platform that can generate millions of high-quality training samples for your model.
Instead of spending months collecting data, you can have it ready in hours.

đź’ˇ Try It Out
Run this in your terminal and start your journey into building LLMs:

npx create-llm my-llm

Let me know what you build — we’d love to feature cool projects on SynthexAI.
