Version Control for LLMs
Version control for LLMs is a system that tracks changes to the code, model weights, datasets, and training runs behind a large language model, so teams can reproduce results, roll back regressions, and collaborate without overwriting each other's work. Diversion provides this in a single Git-like platform that handles multi-gigabyte files and needs no server to manage.
What is version control for LLMs?
Building an LLM produces far more than source code. A single experiment can generate hundreds of gigabytes of model checkpoints, training datasets, evaluation results, and configuration files, all of which change constantly. Version control for LLMs records every version of these artifacts and links them together, so any model can be traced back to the exact data and parameters that produced it. This makes experiments reproducible, audits straightforward, and collaboration safe across a growing team.
From model iterations to algorithm tuning, Diversion keeps your work organized and scalable.
Why traditional version control struggles with AI workloads
Git was designed for small text files, not 40 GB checkpoints or terabyte-scale datasets. Git LFS bolts large-file support onto Git but quickly becomes slow, expensive, and painful to administer at AI scale. Perforce can handle large binaries but requires dedicated servers and specialist maintenance. As a result, many AI teams fall back to copying files into folders named 'final_v2_real', losing history and reproducibility the moment a model misbehaves in production.
Engineers and researchers choose Diversion for AI development to get:
Diversion is a cloud-native version control system that tracks code, model weights, and datasets in one repository, using familiar branch, commit, and merge operations - with no server to provision.
Handles multi-gigabyte files
Version model checkpoints and datasets that are far too large for Git, with fast syncs and no manual LFS setup.
One source of truth
Keep code, weights, data, and configs in a single versioned repository so any model maps to the exact inputs that created it.
Git-like, server-free
Branch, commit, and merge with workflows your team already knows, hosted in the cloud with nothing to administer.
Real-time collaboration
Conflict prevention and live sync let researchers and engineers work in parallel without overwriting each other.

Common use cases
- Reproducing a past model by checking out the exact code, weights, and dataset version.
- Rolling back a fine-tuned model after a regression appears in evaluation or production.
- Comparing training runs across branches to see which data and hyperparameters performed best.
- Onboarding new researchers who can pull a complete, working experiment in minutes.
Frequently Asked Questions
Can I version large model weights and datasets?
Yes. Diversion is built for multi-gigabyte and larger files, so model checkpoints and full datasets are versioned alongside your code without special configuration or storage add-ons.
How is this different from Git or Git LFS?
Git and Git LFS are optimized for small text files and degrade at AI scale. Diversion is cloud-native and designed for large binaries, giving you Git-like branching and merging without the size limits, slow syncs, or server maintenance.
Do I need to manage a server?
No. Diversion is fully cloud-hosted. There is nothing to provision or maintain, so teams can start versioning AI projects in minutes.
Does it support team collaboration?
Yes. Real-time sync and conflict prevention let multiple researchers and engineers work on the same models and datasets in parallel without overwriting each other's work.
