Setting up local LLMs on my new Mac box. Installed Hermes. I do not know what to say. I asked it about models I researched before. Now it's keeping track of my evaluation list, installing and verifying them while I talk to it via SimpleX.

A simple use case for Jev: a skill extracts and sends recommendations from a session friction report to Jev and gets back a ranked adopt/defer/skip scoring of these recommendations. Still fresh but so far this independent scoring aligns better with my own judgement and reduces the noise.

well... this is certainly ...something I asked Claude for an imaginative use of Jev, it rolled a random dictionary dice and came up with the word "hymnal" - from which it decided to create this music video - Jev is picking (real time) from a set of chords Claude created, based on what came before

don’t use Jev at work btw. it’s strictly and only for personal use and you have to ask permission to use it for professional use cases ChatGPT | original typesafe.ai/legal/terms

The clauses that matter to you
1. As written, commercial/developer usage looks awkwardly prohibited.
They grant you a license to use the Site "solely for your personal use." They also prohibit using the Site to "develop new products and services" without TypeSafe's express written permission.
typesafe.ai
That is bizarre for something whose launch announcement explicitly invites developers to build automation with Jev.

btw another form of scam, i see inference providers claiming "99% cache rates" the only provider in the world that hits that right now is deepseek. so this means they are wrapping deepseek then later they switch to a different provider and will continue to claim it

Got access to Siri AI. Asked first 'in vogue' question. "what is Jev the new model by typesafe.ai" not bad. My next question: will this stay free? There must be some part here where Apple will start charging for it.

Here are some results from @typesafeai.bsky.social’s Jev on a common task we have, comparing results with Jev to top frontier models. with zero shots we can achieve nearly frontier levels of accuracy, but if we do a bit extra work we can beat frontier accuracy

Today I started running oMLX to serve small local models on my old(ish) MacBook Pro. Since this machine does not have enough memory to run actually coding models I will be experimenting with specialised models to see how that works out.

Got half of this post highlighted. One direction this AI revolution may be heading is architecture (skills) becoming more important than ever. Eg. Focus on boundaries and coupling between them, properties thereof, behaviour oriented executable specifications decoupled from implementation, etc.

The Death and Rebirth of Programming

Programming didn't die all at once. There was no single moment, no dramatic obsolescence event. Instead, something quieter happened: the core constraint that shaped software for seventy years dissolved. Writing code stopped being the hard part.

be careful in your pursuit of cheap tokens we've come across so many sketchy things that are out there with tons of usage remember you're hooking up your harness to these inference providers. they can and do crazy things like send fake tool calls to steal your info 1/2

If the proposed slow down in AI development by frontier labs ends up restricting access to open weight models instead of focusing on the guardrails and penalties for not keeping track of your swarm of AI agents then we’ll know this was all about their IPOs.

4.1 has been one of the biggest positive surprises for me for a long time. I am now strongly feeling that locking yourself into Anthropic, OpenAI or any other vendor is the wrong way to go. OpenSource harnesses and models are my preference and I think they are going to win.

Two proposals were offered to me. The first was that we post our Euler result, and that OpenAI post its Navier-Stokes result the next day. The second was that, after posting Euler, I alone write a paper presenting the Navier-Stokes result, acknowledging that an internal OpenAI model had resolved it. Sebastien twice asserted that he wanted Levent removed from authorship, and said it would all be simple if only it were not the case that, and it was so annoying that, Levent works at Anthropic. It was also said that if OpenAI posted after us, they would say that we deserved the Clay Prize, and that we were the "closest humans to the problem". I declined both offers.
I said that if OpenAI released its result in the way proposed I would go public with what happened. The reply was, "Why would you ruin your career?" I replied that I am an academic, and asked why he thought going public would ruin my career. The reply was,
"If you don't want me to be nice, then I don't
have to be nice."

If you have a Mistral Pro subscription using Vibe Code may be worth looking into. It's fast! UX is good and the usage limits are generous: €255 worth of GLM 5.2 usage in a month.

Been experimenting further with Herdr: instead of using the built-in subagent system of a specific coding agent, I have the main agent act as an orchestrator that interacts with Herdr to run subagents in separate panes within the same workspace.

Vibe Code allows you to choose if the file systems needs to roll back as well when you traverse your session history. That's different from Pi where the file system remains untouched (the better default). Claude Code used to always rewinded the file system (not sure if that's still the case).
