As someone who still finds typing on a touchscreen incredibly slow and frustrating, I'm very excited about the Clicks Communicator. It's basically a BlackBerry! clicksphone.com/communicator
Even comes with a notification LED!

Has anyone tried the Nyxt browser? nyxt.atlas.engineer
It's cool that it's written in Lisp and comes with a Repl. I'm running into some slow UI updates though.

GPT 5.2 (thinking on high) seems to be buggy. I'm seeing reproducible issues where it starts glitching out in the middle of its response with garbage tokens and then ends the message.
Highly reproducible for me every 10th-20th prompt or so.

Gemini 3 Flash beats Gemini 3 Pro in both ARC-AGI 2 (33.6% vs 31.1%) and in SWE-bench Verified (78% vs 76.2%). 1/4th the cost and faster.
This is very very impressive. Is there still a reason to use 3 Pro?

I do think it's most likely that this was indeed due to teleoperation. But I also think it would be funny if this behavior got accidentally trained into the model due to operator-gathered training data that didn't get trimmed correctly. :D

Claude Haiku 4.5 outperforms Sonnet 4 in some coding benchmarks (such as SWE-bench Verified). This is exciting, since it's 1/3 the price.
However, in my actual use, I've found it to be a bit underwhelming compared to Sonnet 4 (not to mention Sonnet 4.5).
What has been your experience with Haiku?

This is so true.
I think almost nobody is talking about symbolic GOFAI these days, so I'm not concerned about that.
But all of ML being re-branded to AI lately, while AI has simultaneously been made synonymous with generative AI in many places, has led to so much confusion.

The age of single-serving, disposable (simple) software is here. I now frequently have LLMs write software for me that I use exactly once.
Often to convert some data or create visualizations, but also one-off new features to add to some open-source application that I only want to use once.

The funny thing about the prediction that AI would be writing 90% of all code by now is that the prediction's failure distracts from the fact that AI adoption in code writing is actually extremely high, it was already over 30% in December, 2024 according to one measure, with large economic impact.

I remember seeing this graph and thinking it was about the influence of training data on LLM responses as well. Quite misleading.
This chart is everywhere and is being horribly misinterpreted.
This is not where the training data for AI comes from, it is a study done by a SEO firm that claims to show how often sites come up at least once in THE WEB SEARCH FUNCTION of certain AI agents when they do a web search for more info.

I think we're starting to see diminishing returns from LLM pre- and post-training. The limitations of today's LLMs are unlikely to just disappear with the next bigger model.
This is not all bad: we can start focusing on how to work around those limitations and how to put current LLMs to work.
