I guess for mistral it's great marketing material.
Edit: Quite interested in the differences of local optimizations... that does allow for specific sensorship, but alas that's already possible in a more direct, reliable way.

Hey at least "some" news/things from Mistral. Seems like ages ago when they launched vibe-code.
> Powers context-aware search, page summaries, and memory retrieval across browser tabs.
> Live in France and North America, with launches in the UK and Germany planned for later this year.
> Built on a zero data retention policy; conversations are not saved on Mozilla’s servers by default.
> Models are fine-tuned on regional languages, dialects, and local nuances to provide native-feeling responses.
> Extends Mistral’s open-weight AI models directly to consumer web browsing alongside its enterprise offerings.

I'm not a Google fan but I never understood the outrage as it is a local model ... sure, you have to trust them, but if you use their browser you already do.

Reading HN, I 100% understood “private” to be marketing copy for “local inference”.
How else could the information be kept private?
I begrudgingly suppose that there is precedent for the usage, like Apple’s Private Relay, but I really don’t think they are comparable.

Pretty ironic then that here, Mozilla is specifically labeling their "we send it all to the cloud" service as "private."

These (Mistral's and Mozilla's) marketing pages aren't candid enough to clearly explain the difference between local and cloud inference, and that they're asking you to consent to enabling the latter. I'd call that the bare minimum of ethics. If you're in a position of authority over your less technical users, you are ethically obligated to give them the full picture of what are you doing and why they should consent.
(Aside to any Mozilla people who might be reading HN, your page here[0] has an oversight, it advertises this model as "Mistral Small 4" but the hyperlink is to OpenAI's model card for gpt-oss-120b).

In fact, If I were asked to explain the opposite of private, I might give this kind of design as an example.

And look: they were 100% cognizant, then, of how vital local processing is to privacy:
> "...called Project Bergamot. The ultimate goal of this consortium was to build a set of neural machine translation tools that would enable Mozilla to develop a website translation add-on that operates locally, i.e. the engines, language models and in-page translation algorithms would need to reside and be executed entirely in the user’s computer, so none of the data would be sent to the cloud, making it entirely private."

> The assistant sends the full prompt (including your query, any relevant Memories, and any additional relevant browsing context) to a Mozilla server.
>
> Upon receipt, Mozilla forwards the request to a third-party large language model (LLM) on your behalf. The LLM receives the request from Mozilla, not directly from you, and sees a Mozilla IP address rather than your own. The request includes only the information needed to generate a response or perform the requested action.
Where they do use an on-device model is for the initial query classification: > When you submit a query in the Smart Bar, the assistant uses a local (on-device) intent classification model to determine whether the query is best addressed by a chat or a search.

I say this as a person that uses firefox with ublock origin 99.5% of the time. It's better in my opinion than Chrome. I can at least easily turn off the enabled by default crap features. Like the advertising and sponsored news links on the default new tab page.

How small is this 'small model' inference?
Browsers especially are expected to operate on a very wide number of devices. It makes perfect sense to me to start off with a cloud driven approach and later allow people to configure it to run locally if they have the hardware to do so. Anyone with the hardware to do so is already signaling that they'd have the technical interest to make that change while having the default 'works for everyone' mode be one that doesn't require a powerful local device.
I say this as someone using a 6 year old computer and only upgraded to 8GB of ram when the latest WoW expansion was released.
walrus01 3 hours ago | parent
But I also think that the state of the art in small LLM and user device capabilities aren't there yet to put a "good enough to be actually useful" local-only LLM as a prepackaged thing in a mass market distributed browser.
You don't want a browser that takes 10GB of extra RAM (on top of the memory hog that is having just 3 or 4 complex tabs open on its own already) and pegs your CPU at 99% usage for minutes at a time. And not in an era when mass market consumer laptops are still commonly 8GB or 16GB of total system RAM. Many of those with integrated-into-CPU onboard graphics (eg: not a gaming laptop with a discrete GPU on the PCI-E bus).
It'll be a catastrophe for laptop battery life, among other resource use problems. And an LLM that fits in under 8 to 10GB of RAM for CPU-only inference is not going to be nearly as capable as an off-device inference system.
I wish they had just done this with a very clear up front opt in (not enabled by default) thing that explains what Mistral is, that it's not some big American cloud company but a relatively small startup in France, and that your prompts/LLM interactions will go to their servers. And some documentation on how it will be handled/stored in a supposedly trustworthy manner.

Begging the purists to run away from Firefox at this point so they can stop wasting everyone's time. Your demands for examplarity and whining about money not going ONLY to firefox and jerking yourselves on Servo was not enough, now you want to restrict the browser to owners of an RTX5080 if they want to use it?

so then don't add it in as highly advertised feature until it is. doing things right and living up to your core values is a lot to expect from businesses these days but, at minimum, a non-profit foundation should be able to live up to these goals, yes?

I feel it's wrong to tell users that it's important and normal to relinquish all control of their—extremely personal—life history, in bulk, in plaintext, to strangers.
I agree wholeheartedly that remote server inference is super useful, and that local inference falls far short on many tasks. (I have no objection at all to Mozilla providing a cloud inference feature).
What I don't buy is that we must ask users to redraw their personal boundaries so that their most intimate life details, and remote frontier-model inference, overlap. They do not need to overlap.
You can accomplish a lot with private local inference with the smallest of models; and you can accomplish a lot on remote servers which aren't privy to everything. If some convenience is lost by not combining the two, well, so be it. I'm sure most people would agree, if all of this was laid out plainly.

If mozilla is doing things to send users down the path of doing this externally, they need to be much more upfront and transparent with the users about where their data is going, and not bury it in some terms/conditions that only nerds will hunt for.

It's certainly not as capable as something that needs a high memory gpu for quick performance, but I was quite impressed with it for what it is.
(and fwiw, I had it translate your last paragraph to German, then used google translate back to english: "I wish they had handled this clearly and transparently via an opt-in mechanism—not enabled by default—that explains what Mistral is (not a major American cloud company, but a relatively small French startup) and that your prompts and LLM activities are sent to their servers. I also wish there were documentation explaining how the data is handled and stored in a way that inspires trust.").

I acknowledge that this is already the case, to some extent. The cheapest laptops at Best Buy are crammed with the most preinstalled malware. That's been the case for, what, 25 years? But you've always been able to wipe that cheap laptop and make it into a much more capable, trustworthy machine.
Well, assuming LLMs do become a pervasive part of the computing experience, what happens to the cheap laptops? Do all computers get more expensive to accommodate local inference? Does the rift between the everyday user's experience and the savvy user's experience grow even wider than it already is? Neither outcome seems good for the average joe who just needs to check his email.

I certainly agree that this option would be nice to have, but running firefox without an ad blocker on the modern web will ALREADY spin up my fans just rendering all the garbage, and I have a decent laptop.
You can't expect the median Firefox-running device to be able to run a capable enough local model effectively.

Imagine for a moment the complaints that would arise the very next day because their browser is now revving up their laptop fans and hoarding precious RAM.
Local models aren't yet light enough to handle the required processing at the lowest end, so Mozilla chose the most responsible stewards they could find. There is no news here.

I get asked about stuff like browsers all the time, part of the fun of being the token nerd in a small backward town.
From here on out, my response is going to be that both Chrome and Firefox are malware. But, if you're going to use one, go for chrome so your shit at least kind of works.
Mozilla, if you're reading this: Enough is enough. I've had it with these motherfucking clankers in your motherfucking browser!

Edit: after reading the comments, it is not a local AI so "Mozilla don't keeep the data and don't train on them" is really hypocritical if they cannot confirm that it's the same on mistral side. And there is still the question of the cost.

Google Chrome keeps insisting that Spanish is Galician. PowerPoint insists on changing the spell checker back to the wrong language and ignores setting the language for the whole presentation. On Linux, ChatGPT insists it must enable the spell checker in the local system language, so everything is always red.
Privacy aside, a lot of software seems to be built assuming people cannot be multilingual.

"...working together to bring Mistal’s scientific innovations to consumers around the world"
A quick proof-read wouldn't have gone amiss here.
I also fail to see how privacy is enhanced by sending private browsing data to a cloud service which then forwards it to an LLM, in addition to storing 'memories' and dredging through my browser history.

Mozilla is acting unethically by obfuscating what's on offer here and overstating the privacy and security properties that can be achieved.
It's doubly unfortunate because simple translations are completely reasonable to do with cpu inference.
