KoboldCpp

What is KoboldCpp?

KoboldCpp is a single self-contained program that loads a GGUF model file and gives you an interface to write with it. Unlike a front-end, it is both halves at once: the thing that runs the model and the thing you type into. Built on llama.cpp, it offers chat, adventure, instruct and storywriter modes, and it reads Tavern character cards so characters are portable.

At a glance

Product identity

Pricing

Nothing. The llama.cpp and GGML libraries underneath are MIT licensed and the bundled KoboldAI Lite interface is AGPL-3.0. There is no paid edition, no subscription and no account. The only cost is hardware you already own and the electricity to run it.

The whole thing is free. There is no tier structure to compare, no trial that expires and no feature held back behind a payment. Models are downloaded separately and the widely used ones are free too.

Refunds: Nothing is sold, so no refund terms exist.

Platforms

Windows, macOS on Apple Silicon, and Linux, plus Docker, Colab and Android through Termux. It ships as a single executable with no installation, and it runs on CPU alone, on GPU, or with layers split across both depending on how much memory you have.

Feature matrix

Absence of evidence is not recorded as absence of a feature. Anything that needs an account to confirm is marked not tested rather than "no".

Privacy and data

It does not send anything anywhere. The model runs inside the same program you are typing into, on your own machine, so prompts and output stay in local memory and in whatever files you save. There is no vendor holding a retention policy, no training pipeline and no account to delete. The one caveat worth knowing is that it can serve an API, and exposing that beyond your own machine is a decision with consequences you own.

Privacy disclosure

What the vendor lets you know before paying

This measures disclosure, not quality. A good product can document nothing, and that is worth knowing separately from whether it is any good.

Content policy and safety

KoboldCpp documents its output filtering asno documented output filter, and its age policy as none stated.

KoboldCpp does not offer clothing removal from photographs of real people. ClickTug does not list tools that do. Its stated position on the likeness of real people is that documented consent is required.

What the vendor prohibits

• Nothing is enforced by the software, which applies no filter of its own
• What a session refuses depends entirely on the model file you loaded

This is a model runner. It contains no content policy and cannot enforce one: the behaviour you get belongs to the GGUF file you chose, and the responsibility for what it produces sits with you and the law where you live.

KoboldCpp runs on your own hardware, so it receives none of what you generate. ClickTug does not require a minor safety policy or an acceptable use policy from a tool that never receives user content, because there would be nothing for such a policy to govern. Any optional hosted tier is a separate service under its own terms.

ClickTug content policy

ClickTug verdict

The shortest path to running a model on your own hardware, and one of two entries here with no vendor at all. KoboldCpp is a single executable that is both the model runner and the interface, with chat, adventure and storywriter modes and Tavern card support. Nothing leaves your machine, so there is no retention policy, no training question and no account to delete. In exchange it enforces nothing: the behaviour you get belongs to the GGUF file you chose, and there is no support, no warranty and nobody accountable.

Quick answers about KoboldCpp

Generated from the same records as the tables above, so an answer here cannot contradict a figure there. Questions only appear when the answer says something specific to this product.

Is KoboldCpp free?

There is a free tier. The whole program. No paid version, no account, no service to subscribe to.

How much does KoboldCpp cost?

No price is published. Free and open source. The llama.cpp and GGML libraries underneath are MIT licensed and KoboldAI Lite, the bundled interface, is AGPL-3.0. There is no paid edition.

Does KoboldCpp require a credit card to start?

No card is required to reach the free layer. One is needed for any paid plan.

Does KoboldCpp offer refunds?

Nothing is sold, so no refund terms exist.

Does KoboldCpp have an app?

Yes, on Android.

Can KoboldCpp run locally?

Yes. It runs models on your own hardware, so prompts and output never leave the machine and the retention question does not arise.

Does KoboldCpp train on my conversations?

The vendor states it does not use user content to train models. That is a written commitment, and rarer in this category than it should be.

Can I delete my KoboldCpp account?

Yes, through a control in the account rather than by asking support.

Can I use KoboldCpp without an account?

Yes. The service can be reached without registering, which almost nothing else in this directory permits.

Is KoboldCpp actually uncensored?

ClickTug records no documented output filter, which is a different claim from having no rules: its terms still prohibit a specific list of conduct, set out above.

What company owns KoboldCpp, and where?

KoboldCpp project, maintained by LostRuins, Not applicable, open-source project. Publishing an identifiable counterparty is worth noting: several tools in this directory name no company at all.
