Why Fenn Will Always Use Open-Source Models ?
Why Fenn Will Always Use Open-Source Models ?
We do not know if you have followed the recent drama around OpenAI, Anthropic, and frontier AI models.
Here is the short version.
AI executives from OpenAI and Anthropic have spent countless hours saying that their models are too dangerous, that they will lead to mass unemployment, and that society needs to treat them like something close to a national security asset.
Maybe some of those concerns are real.
But let’s be honest.
This is marketing.
“Too dangerous to release” is a powerful story.
It makes the model sound forbidden.
It makes the company sound important.
It makes access feel like a privilege.
We have already seen this movie before. GPT-2 was once treated as too dangerous to release too.
What happened with Fable 5?
Anthropic released Fable 5, a new state-of-the-art model from its Mythos-class family.
Then the U.S. government restricted access to Fable 5 and Mythos 5.
After that, access was restored.
So the model was available.
Then restricted.
Then available again.
Until the next drama.
That is exactly the problem.
If your workflow depends on a cloud model, you do not really own the tool.
A government can restrict it.
A company can remove it.
A policy can change overnight.
A safety rule can modify the output.
A model can become unavailable for reasons you do not control.
The model can also be nerfed
The even bigger issue is not only access.
It is output control.
Users learned that some requests could be handled differently when Anthropic’s safeguards were triggered.
That means you can pay for a model, ask a question, and not always know when the answer has been degraded, redirected, or restricted.
Think about what that means.
Anthropic can reduce the quality of the response without clearly telling you why, when, or how.
And you still pay the same.
That is not a small product detail.
That is a huge trust problem.
Privacy makes it worse
Fable 5 also came with a 30-day retention requirement for Mythos-class model traffic.
Anthropic says that retained data is for "safety" monitoring.
But for confidential work, that is really bad.
If your prompt contains a private contract, a legal memo, source code, client data, an internal strategy document, or a business secret, why should you upload it in the first place?
Why should a third-party company retain it?
Why should your private work depend on someone else’s retention policy?
This is the wrong default for confidential files.
This confirms our choice from day one !
At Fenn, this episode only strengthens the choice we made from the beginning.
Fenn relies on open-source models by default.
Open-weight is the more precise term, but the principle is simple:
The model runs on your machine.
Your files stay on your machine.
Your searches stay on your machine.
Your private work do not depend on anyone.
Local models cannot be shut down by a provider
A model running locally is different.
It does not need internet access to work.
It cannot be quietly swapped during your session.
It cannot be nerfed by a cloud provider.
It cannot be restricted to one nationality or one market by an API gate.
It cannot be shut down by Anthropic, OpenAI, Google, Microsoft, or even us.
Once the model is on your machine, you own that workflow.
That is the whole point.
Local models are not always the strongest
To be honest, local models are usually weaker than the best models from OpenAI or Anthropic.
That is real.
Cloud frontier models are faster, bigger, and more capable.
But this is the price of privacy, sovereignty, and freedom.
For some tasks, maybe you want the strongest cloud model.
But for searching your private Mac, reading confidential files, indexing documents, organizing folders, renaming files, chatting with sensitive work, and retrieving personal or business information, the default should not be cloud upload.
The default should be local.
We will not build Fenn around a model we do not control
We refuse to build a product around a model that can be shut down, banned, restricted, nerfed, or limited to specific users by a company or government.
We refuse to ask users to send all their confidential files to AI companies just to make their own Mac searchable.
Fenn is Private AI that finds what you have saved, saw or heard on your Mac.
That means local by default.
Open-source models by default.
Your files on your Mac.
Your searches on your Mac.
Your private work under your control.
The bottom line
The Fable 5 episode is not just an Anthropic story.
It is a real and big warning about cloud AI.
If the model lives on someone else’s servers, the rules can change.
If the model runs on your machine, you stay in control.
This is why Fenn will always use open-source models by default.
