Republicans against Trump
NEW: Donald Trump has terminated the remaining members of the independent, federal commission that assists election administration officials nationwide just a few months before the midterm elections
“It is irresponsible and dangerous that this Administration remains dead set on causing chaos for our election officials across this country,” Arizona secretary of state Adrian Fontes said in a Thursday statement. “This move undermines the integrity of nonpartisan election administration.”

Meta AI chief @alexandr_wang told me the company sees its new API for selling AI models as a real business, not just a learning exercise.
Tokens are “gigantic and growing very, very quickly,” he told me, and capturing even a slice of that “can be a very meaningful business even for Meta at our scale.” https://sources.news/p/why-meta-selling-ai-models

Today, together with @kyutai_labs, we’re introducing our new Audio-to-MIDI model.
It takes a finished recording, identifies the instruments playing, and returns separate MIDI tracks for each — voice, drums, bass, keys, and more.
Unlike most existing solutions, our model works directly from the full mix rather than requiring separate stems.
It also detects chords, key, and tempo, giving producers broader musical context.
We’ve written more about the model, the problem, and how it works here: http://mirelo.ai/blog/turning-audio-to-midi

GPT-5.6 is now the preferred model in Microsoft 365 Copilot

I am deeply grateful for all Fidji has done for OpenAI and to advance our mission, and for the opportunity to have worked alongside her for the past few years.
It’s quite sad, but I’m glad that she’s taking the time to work as hard on her health as I’ve seen her do professionally — hoping for a quick recovery.
Fidji Simo: Today, I shared with the OpenAI team that I have decided to leave my full-time role at OpenAI and transition to being a part-time advisor.
Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived with for seven years. During that

ChatGPT Voice is a real advance.
We’ve always had to contort ourselves to our computers. Now feels like we’re entering a new era of a natural interface.
Expect that we’ll soon spend much less time staring at screens, and regard today’s apps as painfully user-unfriendly.
Ethan Mollick: The new ChatGPT voice is quite impressive to use, really worth a minute to try it out on your phone. (while staying aware that the voice model is not going to be as smart as a full thinking model)
One thing to point out - I never thought about usage at all on 5.5 high fast mode. It felt basically unlimited.
5.6 Sol high fast mode burns through usage pretty fast. Going to switch 5.6 Sol medium no fast mode to see how it does on browser use and other tasks.
Peter Yang: OpenAI just made GPT-5.6 available to everyone, so I wanted to answer the most burning question:
Is GPT-5.6 better than Claude Fable 5?

→ Frontend design (5.6 has closed the gap)

Hello beautiful people! We have reset usage limits across Codex and ChatGPT Work. And another one will come later in the day. Rejoice.
Now that I have your attention, a quick update on ChatGPT Work, Codex and all the updates we shared yesterday.
We’ve spent the last 24 hours reading feedback, looking at usage patterns, and talking with many of you. The short version is that there is a *lot* of excitement for GPT 5.6 Sol, ChatGPT Work on mobile & web, but also that we didn't get everything quite right.
- We made it too easy to use the highest-compute settings without making the impact on usage limits sufficiently clear.
- We reorganized the desktop app in one bold move, making familiar things like chats and projects harder to find.
- Our launch framing was focused on ChatGPT Work and to some of our Codex fans it made it feel like Codex was going away over time. Absolutely not our intention, we love Codex and it is here to stay.
- And we introduced regressions for some existing multi-agent workflows, alongside a collection of rough edges in plugins and other parts of the experience.
We’re landing a first set of improvements today. We’re resetting usage twice so people can keep experimenting, changing defaults and the model picker so they don’t push people toward unnecessarily expensive settings, fixing several plugin submission issues, improving how we represent Codex in the product, and cleaning up some of the most immediate desktop problems.
A larger set of improvements will land next week. We’re bringing chats and projects back into the sidebar in a more familiar and customizable way, making usage and reset timing much more visible, clarifying when to use ChatGPT Work and when to use Codex, and addressing the many other smaller pieces of great feedback we've had.
The ambition behind this launch hasn’t changed. We think bringing ChatGPT and Codex together into a workspace where people and agents can collaborate is a very important step forward. But an ambitious direction doesn’t excuse avoidable confusion or regressions in the first version.
Please keep the feedback coming. We’re moving quickly, and you should see the experience already get better with a few updates today; and substantially better again next week.

All foundation models are in fact models of knowledge, mainly based on open knowledge already developed by mainkind. Obviously knowledge (models) of mankind should be open sourced! (Again, please do not confuse knowledge with intelligence.)
