What is nanochat?
nanochat is a full-stack implementation of an LLM like ChatGPT in a single, clean, minimal, hackable, dependency-lite codebase. Run tokenization, pretraining, finetuning, evaluation, inference, and web UI on a single 8XH100 node.
Problem
Users face high costs and complexity with existing large language models (LLMs), requiring expensive infrastructure and fragmented dependencies. High cost and dependency-heavy codebases limit accessibility and customization.
Solution
A minimal, hackable codebase enabling users to run end-to-end LLM workflows (tokenization, pretraining, inference, etc.) on a single node. Full-stack implementation of an LLM like ChatGPT in a single codebase simplifies development and reduces costs.
Customers
AI developers, researchers, and engineers needing cost-efficient, customizable LLM solutions; startups and academic labs with budget constraints.
Unique Features
Single codebase covering all LLM lifecycle stages (pretraining to web UI), dependency-lite design, optimized for 8x H100 GPU nodes, and open-source flexibility.
