A storage for project code with a full change history: who, when, and what was modified. Allows reverting to any previous state and managing multiple versions in parallel.
Why it matters
Change history is the only reliable record of how a system was built. Without it, after a failure, you won’t know what changed or what to revert to.
What's missing without it
Without a repository, team collaboration ends in overwriting each other’s changes, and every bug requires reconstructing code from memory.
When it is used
In every software project. Also used for AI models — they are published in repositories on Hugging Face.
How we use it
A model repository is not the same as a code repository: the former stores files up to several gigabytes and requires special handling for large files.
