I am strongly put off by the LLM writing in this piece. It makes me question quality of the project before even attempting a download. Who would put effort into building this only to compose a low effort puff piece?

What gives you the sense that the piece was written by an LLM? I would agree that the diagrams have some of the artifacts common in Nano Banana output, but what tips you off about the text?

Em dashes in every other sentence. I've never seen an actual person do that. The language in general reads exactly it's written by an LLM:

"The blah blah didn't just start as blah. It started as blah..." "First came blah -- blah blah blah" "And now: blah"

It's a distinctly AI writing style. I do wonder if we'll get to a point where people start writing this way just because it's what they're used to reading. Or maybe LLMs will get better at not writing like this before that happens.

Not sure if this will help but I've set up Handy [1] with Parakeet V2 for STT and gpt-oss-120b on Cerebras [2] for post-processing and I'm happy with the performance of this setup! [1] https://handy.computer/ [2] https://www.cerebras.ai/

parakeet v3 is also nice, and better for most languages.

The latest build of Handy actually supports Parakeet V3 (among other models) under the covers. Agreed that it's a very solid multilingual model.

I would like my phone to forward spam calls to this, with a system prompt to slowly provide fake personal and financial information intermingled with chatter about sports and the weather.

Yeah; that and spam texts. "I have no idea who the person you were trying to reach is, but, yes, the recent weather patterns have created strange surges in my dishwasher. The karmic energy of my spoons is all off. I am interested in having you maintain all my appliances. I'm a landlord and own 25 nude goat yoga worship rooms. They go through a lot of dishes!"

Bonus points if it correlates the spam texts with follow up phone calls from the spammers.

> The chatbot took on a persona that Gavalas hadn’t prompted That's an interesting claim, how can we be sure of it? If Gavalas didn't have to do anything special to elicit the bizarre conspiracy-adjacent content from Gemini Pro, why aren't we all getting such content in our voice chats? Mind you, the case is still extremely concerning and a severe failure of AI safety. Mass-marketed audio models should clearly includ…

Yeah the case is quite terrifying. It reminds me of an episode of Star Trek TNG, if memory serves correct there were loads of episodes about a crew member falling for a hologram dec character. Given that there’s a loneliness epidemic I believe tech like this could have a wide impact on peoples mental health. I stronger believe AI should be devoid of any personality and strictly return data/information then frame its…

This sounds quite dangerous https://www.theguardian.com/technology/2026/mar/04/gemini-ch...

I really think a small amount of education on what LLMs actually are (document completers) and how context works (like present it as a top-level UI element, complete with fork and rollback) would solve most of these issues.

Given how they work, it's really not surprising that if it sees the first half of a lovers' suicide pact, it'll successfully fill in the second half. A small amount of understanding of the underlying technology would do a lot to prevent laypeople from anthropomorphizing LLMs.

I get the impression that some of today's products are specifically designed to hide these details to provide a more convincing user experience. That's counterproductive.

But isn't it normal for people who work on AI stuff to use LLMs for everything? They are very enthusiastic about AI so naturally they'll use it on everything they can.

Sometimes I wish they just posted the prompt, not everything has to go through an LLM blender before posting.

I'm sick and tired of the "No..., no ..., (just) ..." LLM construction. It's everywhere now, you can't open a social media platform and get bombarded by it. This article is full of it.

I get it, I should focus just on the content and whether or not an LLM was used to write it, but the reaction to it is visceral now.
