llamafile

llamafile: a whole model in one runnable file

One file that is both the model and the program. No installer, no account, maintained by Mozilla.ai.

Last verified Uncensored AI

What is llamafile?

llamafile collapses a language model and the software that runs it into one executable file. Built on llama.cpp and Cosmopolitan Libc, a single file runs across most operating systems and CPU architectures without being installed or even unpacked: you download it, make it executable and run it. It is maintained by Mozilla.ai out of a Mozilla Builders initiative.

Who it is for

People who want local AI with the setup step removed entirely, and people who need it portable. One file on a USB stick runs on a Mac, a Linux box and a Windows machine, which no other entry here manages. It also suits anyone archiving a specific model, since the file is self-contained rather than depending on a runtime that may change.

Who it is not for

Anyone wanting an application. There is no character system, no roleplay tooling, no images and no polished interface: this is a runnable model with a minimal front end. Anyone who wants to switch between many models quickly will find a model manager like LM Studio or Jan less awkward.

Pricing

Nothing. Apache 2.0, with the llama.cpp and whisper.cpp modifications deliberately kept MIT licensed so they can be contributed back upstream. There is no paid edition, no subscription and no account. Model files are downloaded separately or come packaged inside the executable.

The entire project is free. There is no tier structure and nothing held back. What you supply is a machine, and llamafile is unusually forgiving about which one: it runs on CPU, so a GPU is optional rather than assumed.

  • The complete project, Apache 2.0
  • Single-file executables that need no installation

No paid edition exists.

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

Signup friction

There is nothing to sign up for at all. No account, no email and no card. Combined with the fact that nothing is transmitted, this is among the few genuinely anonymous entries in the directory.

  • No card at signup
  • No account required
  • Anonymous use supported

Platforms

Most operating systems and CPU architectures from the same file, including macOS, Linux, BSD and Windows. Windows imposes a 4GB executable size limit, which matters when a model is packaged inside the file, so larger models are loaded alongside it instead.

Privacy and data

It cannot do anything with your data, which is the strongest version of this answer. The model runs inside the executable on your own machine, nothing is transmitted, there is no account and there is no vendor. Retention is whatever you choose to save to your own disk. The only caution is about provenance rather than privacy: a llamafile is an executable, and one downloaded from an unknown source deserves the same suspicion as any other program from an unknown source.

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

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

llamafile 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 project, which is packaging rather than a model
  • What a file refuses is a property of the model weights packaged inside it

General-purpose infrastructure rather than an adult product. It is packaging technology: behaviour belongs entirely to the model someone chose to package, and a llamafile downloaded from a third party is only as trustworthy as its source.

llamafile 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 verdict

The most portable local AI in this directory and the least like an application. llamafile packages a model and its runtime into a single executable that runs across most operating systems and architectures with no installation, free under Apache 2.0 and maintained by Mozilla.ai. Nothing is transmitted, there is no account and there is no vendor, so the privacy answer is architectural. Against that: a minimal interface, no roleplay or character tooling, a 4GB executable limit on Windows, and the ordinary caution that an executable from an unknown source deserves suspicion.

Strengths

  • One file runs across most operating systems and CPU architectures with no installation
  • Apache 2.0, with upstream modifications kept MIT so they remain contributable
  • Maintained by Mozilla.ai rather than an individual, which is rare for local AI infrastructure
  • Runs on CPU, so a GPU is optional rather than assumed
  • Self-contained, so a model can be archived as a single artefact that still runs later

Portability and permanence. One file that runs on three operating systems removes the entire class of problems about dependencies, runtimes and environments, and it means a model can be archived as a single artefact that will still run later. Mozilla.ai maintaining it is worth something too: most local AI infrastructure is an individual maintainer, and this has an organisation behind it.

Limitations

  • Minimal interface. No characters, roleplay tooling or images
  • Windows imposes a 4GB executable limit, constraining packaged model size
  • A llamafile is an executable, so provenance matters more than with a passive model file
  • Applies no content policy, because it is packaging rather than a model
  • General-purpose infrastructure rather than a product built for this category

It is closer to infrastructure than to a product. The interface is minimal, there is no character or roleplay tooling, and switching models is more awkward than in a purpose-built manager. The Windows 4GB executable limit is a real constraint on packaging larger models. And because a llamafile is an executable, downloading one from an untrusted source is a genuine risk in a way that downloading a passive model file is not.

Hands on

Every other local AI entry in this directory is a program plus a model plus some configuration joining them. llamafile is one file that is all three.

It uses Cosmopolitan Libc, which produces executables that run across most operating systems and CPU architectures from the same binary. Download the file, make it executable, run it. No installer, no runtime to match, no Python environment, no dependency that will break in six months. The same file on a USB stick runs on a Mac, a Linux server and a Windows machine, and nothing else here comes close to that.

The privacy position needs no argument. The model runs inside the executable on your own machine, so nothing is transmitted, there is no account and there is no vendor. This is the local cluster’s usual answer and llamafile gives the cleanest version of it, because there is not even a separate program keeping conversation files.

Two practical constraints. Windows limits executables to 4GB, which matters when the whole point is packaging a model inside the file, so larger models get loaded alongside rather than embedded. And the interface is minimal: this is a runnable model with a basic front end, not an application. No characters, no roleplay tooling, no images.

There is one caution worth stating that does not apply to the other local tools here. A llamafile is a program, not a passive model file. Running one you downloaded from an unknown source is the same category of decision as running any other unknown executable, and the convenience that makes this project excellent is exactly what makes that worth thinking about. Prefer files from sources you would trust with a normal application.

Mozilla.ai maintains it, out of a Mozilla Builders initiative. Among the local tools listed here that is unusual: most are an individual maintainer or a community, and an organisation behind a project is a reasonable proxy for whether it will still be maintained in two years.

Quick answers about llamafile

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 llamafile free?
There is a free tier. The whole project. No paid tier, no trial, no account and no card at any point.
How much does llamafile cost?
No price is published. Free and open source under Apache 2.0, with the llama.cpp and whisper.cpp modifications kept MIT licensed so they remain upstreamable. No paid edition and no account.
Does llamafile require a credit card to start?
No card is required to reach the free layer. One is needed for any paid plan.
Does llamafile offer refunds?
Nothing is sold, so no refund terms exist.
Does llamafile have an app?
No. It runs in a web browser only, which is common for adult products because both app stores restrict them.
Can llamafile 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 llamafile 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 llamafile account?
Yes, through a control in the account rather than by asking support.
Can I use llamafile without an account?
Yes. The service can be reached without registering, which almost nothing else in this directory permits.
Is llamafile 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 llamafile, and where?
Mozilla.ai, from a Mozilla Builders initiative, Not stated in the repository. Publishing an identifiable counterparty is worth noting: several tools in this directory name no company at all.

llamafile FAQ

Is llamafile free?

Yes. Apache 2.0, with the llama.cpp and whisper.cpp modifications kept MIT licensed so they remain compatible and upstreamable. There is no paid edition, no subscription and no account. Model files are downloaded separately or come packaged inside the executable itself.

What makes llamafile different from other local AI tools?

It is one file. Other tools are a program you install plus a model you download plus configuration between them. llamafile uses Cosmopolitan Libc to produce an executable that runs across most operating systems and CPU architectures without installation, so the same file works on macOS, Linux and Windows. Nothing else in this directory does that.

Does llamafile need a GPU?

No. It runs on CPU, which is the point of its portability: assuming a specific GPU would defeat the purpose of a file meant to run anywhere. A GPU makes generation faster where one is available and is not required for it to work.

Does llamafile send anything to a server?

No. The model runs inside the executable on your own machine, so prompts and output are never transmitted. There is no account, no vendor and nothing to delete because nothing was sent. The caution here is about provenance rather than privacy: a llamafile is a program, so one downloaded from an unknown source deserves the same suspicion as any other unknown program.

Who maintains llamafile?

Mozilla.ai, out of a Mozilla Builders initiative. That is worth noting because most local AI infrastructure is maintained by an individual or a loose community, and having an organisation behind a project affects how likely it is to still be maintained in two years. No jurisdiction is stated in the repository.

Is llamafile an adult AI tool?

No, and it is listed on that basis openly. It is packaging technology, included because ClickTug covers the local cluster where running a model yourself removes the retention and filtering questions rather than answering them. What any packaged model does is a property of those weights, not of llamafile.
