Is there a voice chat mode in any chat app that is not heavily degraded in reasoning?

I’m ok waiting for a response for 10-60 seconds if needed. That way I can deep dive subjects while driving.

I’m ok paying money for it, so maybe someone coded this already?

What the current preferred subscription on AI?

OpenAI and Anthrophic is my current preference. Looking forward to know what others use.

Claude Code for coding assistance and cross-checking my work. OpenAI for second opinion on my high-level decisions.

I'm continuously surprised that some people get good results out of GPT models. They sort of fail on my personal benchmarks for me.

Maybe GPT needs a different approach to prompting? (as compared to eg Claude, Gemini, or Kimi)

They are all gpt as in generative pre-trained transformer

That may or may not be true, but in the context of this article, I'm referring to OpenAI's GPT brand of models.

A bit off topic: but what's with the ram usage of LLM clients? ChatGPT, google, and Anthropic all use 1+ GB of ram during a long session. Surely they are not running GPT 3 locally?

Sweet Jesus. 53% on ARC-AGI-2. There's still gas in this van.

Man this was rushed, typo in the first section:

> Unlike the previous GPT-5.1 model, GPT-5.2 has new features for managing what the model "knows" and "remembers to improve accuracy.

petercooper 12/11/2025|
Also, did they mention these features? I was looking out for it but got to the end and missed it.

(No, I just looked again and the new features listed are around verbosity, thinking level and the tool stuff rather than memory or knowledge.)

Is this why all my Cursor requests are timing out in the past hour?

Somewhat tangential: The second link says "System card": https://cdn.openai.com/pdf/3a4153c8-c748-4b71-8e31-aecbde944...

Does that term have special meaning in the AI/LLM world? I never heard it before. I Google'd the term "System Card LLM" and got a bunch of hits. I am so surprised that I never saw the term used here in HN before.

Also, the layout looks exactly like a scientific paper written in LaTeX. Who is the expected audience for this paper?

tylerrobinson 12/12/2025||
The major model providers use system cards as a sort of self attestation document like a nutrition label. It’s been around for a couple years.
blinding-streak 12/12/2025||
Yeah, search HN for the term. It's a relatively big topic of conversation.

In other news, been using Devstral 2 (Ollama) with OpenCode, and while it's not as good as Claude Code, my initial sense it that it's nonetheless good enough and doesn't require me to send my data off my laptop.

I kind of wonder how close we are to alternative (not from a major AI lab) models being good enough for a lot of productive work and data sovereignty being the deciding factor.

Nesco 12/11/2025||
Wait, isn't Devstral2 (normal not small) 123b? What type of laptop do you have? MacBooks don't go over 128GiB
cc62cf4a4f20 12/11/2025||
I'm using small - works well for its size
yberreby 12/11/2025||
Would you share some additional details? CPU, amount of unified memory / VRAM? Tok/s with those?
cc62cf4a4f20 12/12/2025||
MBP M4 Max 64MB - haven't measured the tokens/sec, feels slower than Claude, but not unbearably

It's not yet perfect, my sense is just that it's near the tipping point where models are efficient enough that running a local model is truly viable

How can I hide the big "Ask ChatGPT" button I accidentally clicked like 3 times while actually trying to read this on my phone?

I guess I must "listen" to the article...

With Safari on iOS you can hide distracting items. I just tried it on that button, it works flawlessly.
