Voice mode also supports more languages, on every plan, including Spanish, French, Hindi, and Japanese.

The update is rolling out today in public beta on mobile, desktop, and web. Download the mobile app and tap the sound wave to start a conversation: https://t.co/hwPB3zlk0w

Voice conversations now use more of the models you have in chat, including Claude Opus and Sonnet. Claude can also reach the tools you've connected mid-conversation, like your email and calendar. https://t.co/452G2ZZY1d

Voice mode now runs on Claude's more capable models and reaches the tools you've connected mid-conversation.

Talk through the hard problems out loud, in many more languages. https://t.co/k0CWAGjLdK

The best way to think about AI is as a force multiplier for the fields you already know about (or for the rate at which you want to learn about a new one). The 3rd category -no existing judgment, no interest in developing it- will basically produce slop and won’t drive that much economically productive activity.

What will happen is that the experts will get better and better at their craft and be able to do so much more. Because they can wield these tools in ways that actually drive high quality output, veer agents in the right direction when they go off, and actually incorporate the work into something useful.

The expert engineer with agents will do far more productive work, precisely because they know how to steer the agent properly. The designer will product far better outcomes using AI than someone without an eye for design. And so on.

As a result of this dynamic, specialization will continue to be important, if not even more so as the tools get more powerful. Because the expectation of the market gets to be much higher. Getting good at any craft will continue to be necessary in the future.

Amjad Masad

Autoscale deployments, which is typically the most expensive of scaled apps is down 80%! https://t.co/5Thud2waXD https://t.co/mUJwAzV2Xu

My chess autoresearch agent got a PhD in modern LLM finetuning. https://t.co/xw9mvVRhgY

Viktor was able to disrupt the agency model and make a lot of money by using Replit.

Then he figured: Why not automate the entire thing, not just the coding part?

The Agency: It's merely an agent loop...

So he asked our team for an MCP, and we built one and he's now built his autonomous agency.

The next evolution is being able to spin up multiple ChatGPT Voice threads so I can have a full team talking to me and to each other. 🔥

Before and after with ChatGPT Voice https://t.co/kzNE5odHSy

More feedback:

1. It should let me know when the other threads finish working if I have a bunch of threads going

2. The Chinese pronounciation sounds bad 😅

Things in tech that have lost all signal given how liberally we use this title..

> “neo”-something
> full stack
> fellows*
> labs
> partner*
> forward deployed
> RL (getting there slowly)

* yes I know the irony since a) we run a fellowship and b) my own title is partner

Swyx

btw ive been dogfooding an agentic github clone over the past month or so and its gotten quite quite enjoyable to use. even complete with built in CI/CD thanks to workers for platforms!

there's 3 more ideas i have to implement (not shown here) before this goes live. but if you're looking to hack on this with me it's a really good time to join swyx inc and influence the roadmap

one thing i think people dont appreciate enough about @poolsideai is their unusual degree of openness — not only have they shipped an excellent Small model that somehow beat @thinkymachines at coding, but most people (like @eliebakouch) have been shouting out their excellent papers, but also they're among a rare few to actually expose their full eval dataset as well - beautifully published, with across 6 public benchmarks with 4 runs each and hundreds of turns per run. you can satisfy for yourself if they rewardhack. brilliant.

Great builders understand the jagged frontier of AI models.

Great leaders understand the jagged frontier of their people.

Chatted with a friend who leads security at a public company following the GPT Sol incident. some interesting takeaways..

How do you manage security for effectively infinite agents when identity and access management was designed for a finite number of employees?

One employee can now spin up hundreds of agents. Those agents can spawn more agents.

Traditionally, each employee has an identity, a role, permissions, and a lifecycle.

Do agents inherit the spawning employee’s permissions? What’s their lifecycle - a task, a ticket, a week? Do child agents inherit the same permissions? How do you audit all of this?
