nanochat

Rookie of the month

The whole path from zero to your own ChatGPT-like chat in one repo: tokenizer, pretraining, fine-tuning and UI. Designed to train for roughly a hundred dollars.

Who it is for

For people who want to go through the full chat-model build cycle themselves on one GPU machine.

How to start

  1. Set up the environment: uv sync --extra gpu (or --extra cpu for CPU and MPS).
  2. Run the full pipeline: bash runs/speedrun.sh (built for an 8xH100 node, about 1.5 hours).
  3. Talk to your model: python -m scripts.chat_cli.

Steps are taken from the README. Check the current version in the repository before running them.

The best ChatGPT that $100 can buy.

ollama

ollama

The easiest way to run an open model on your own machine: one command downloads and starts it, plus a local REST API and libraries for Python and JavaScript.

huggingface

transformers

The core library for working with models: one codebase for text, vision, audio and multimodal tasks, for both inference and training. Most new open models ship through it.

open-webui

open-webui

A self-hosted ChatGPT-style interface that connects to Ollama and any OpenAI-compatible API. Installs with a single Docker command and runs on your own server.

ggml-org

llama.cpp

A C/C++ engine that runs language models on ordinary hardware: laptops, phones, GPU-less servers. Much of local AI, Ollama included, is built on it.

deepseek-ai

DeepSeek-V3

Repository of the large open DeepSeek-V3 mixture-of-experts model: description, benchmark results and run instructions. It showed an open model can stand next to closed ones.

pytorch

pytorch

The foundation under most modern neural networks: GPU-accelerated tensors and automatic differentiation, wrapped in ordinary Python. Transformers, Llama and nearly every open model are written on it.
