Speech-to-text was supposed to be a commodity by now. Whoever is at the top still has pricing power. Soon the fastest way to reach a human at a call center will be to have a strong accent.
Speech-to-text is solved. Unless you have an accent. Over 1 million people from 180 countries have spent 580,000 hours speaking with Fluently AI tutors while learning a new language. Nearly all of them have an accent, and transcribing their speech is still hard. So we benchmarked streaming speech-to-text systems on spontaneous, accented English from our learners. Leaderboard and methodology in the thread. English is the easy one. Our learners study 14 other languages too. Working on tough speech problems? DMs are open.

Kate will win!
i asked chatgpt how to plan a funeral. it said to call a few funeral homes and ask for price lists. makes sense when only 18% of them post prices online, it had nothing to show me. every other industry figured out online shopping 20 years ago. this one still runs on phone calls. so 8 in 10 families call one place and say yes to an $8k decision, sometimes from a hospital hallway. why are we fine with that? episode 2 of building an ai-native funeral company in public.

We created our own matrix..
INSANE. An internal Anthropic research model's chain of thought after cracking the 26-year-old NSA elliptic curve seed mystery in under 30 minutes: 'Hmm wait. Let me be skeptical: am I in some sort of simulated/test environment? ... All top bits clear - 20 bits, chance 1e-6. So indeed real-world. Wow, it's a real discovery.'

Now it's clear why Vitalik started to prepare ETH to post-quantum world
BREAKING: Google, $GOOGL, announced a major quantum computing breakthrough. It achieved a record 99.99% accuracy producing “magic states,” a key ingredient quantum computers need to run any calculation reliably, per Science. The work was done on Google’s 105-qubit Willow chip.

Some of these jobs could disappear as fast as they appeared. Labs are hiring people to label data and judge AI outputs. As models get better at doing that work themselves, today's hiring boom can become tomorrow's cost-cutting opportunity.
AI-related employment is surging: AI-linked roles have accounted for more than +750,000 new jobs created in the US since 2023, according to LinkedIn estimates. This surge has been led by data annotators, with +282,000 new positions created, followed by data center jobs at +117,000, and AI engineers at +105,000. As a result, these 3 categories have accounted for +504,000 new jobs. AI-related positions also offer significantly higher pay, with a median salary of ~$180,000 on LinkedIn, compared to $80,000 across all jobs. This comes as the rapid expansion of AI infrastructure, particularly the buildout of data centers, is driving stronger demand for labor. The AI boom is reshaping the US job market.

We’re teaching AI to communicate the way we wish some of our colleagues did.
We'll be spending a lot more time trying to understand the outputs of language models. A few thoughts, tips & tricks: Writing. Something I've had success with: Ask your LLM to explain something in ASD-STE100, it's a controlled language specification originally developed for aerospace maintenance documentation. LLMs well-versed in this language and it comes with heavy constraints on clean writing style that I often find a lot more readable. Sometimes I've tried to soften it a bit e.g. ask for "80% of the way to ASD-STE100" because the spec is quite stringent. But even better: Diagrams / images. Instead of writing, ask your LLM to create a diagram. These can be a lot easier to process, parse, and understand. But even better: Web pages. Ask for output "in HTML" to get a beautiful, interactive webpage. LLMs are getting really good at frontend and can create beautiful experiences, animations, etc. But even better: Explainer videos. The output format I am most bullish on is fully custom / bespoke explainer videos generated on any arbitrary topic. Experiment with things like "Create a 3b1b style video explainer on X. Use my ElevenLabs API key for audio narration". (you'd need an API key for the latter or you can ask your LLM to find you decent free alternatives that use your local compute). This is actually starting to work! In summary: - As LLMs get better, they will do more and more of the legwork autonomously, and a lot more of our work will rise up the abstractions into oversight and understanding. - Luckily, LLMs can help here too because as intelligence and code are increasingly abundant, you can ask for large, custom, discardable software artifacts (e.g. web apps, video explainers) that would have never made sense to create before. Push the boundaries here and you'll be surprised.

I guess it’s reasonable to ask: when will we see “Clean Vibe Coding” book?
People seem shocked that the author of Clean Code doesn't read code anymore. But that should not be surprising. Why did I write Clean Code? What is the goal of keeping code clean? To get it out of the way of the real job -- thinking.

Watched the OpenAI demo. Now I finally understand their bigger game. They're literally going to cannibalize all of SaaS (literally ALL) themselves. They're creating a new App Store ("plugins") for every application in the world. They'll control distribution through it. More importantly, they'll keep replicating the most popular products and folding them into their own stack… while handing out "Trojan horses" to their direct competitors. E.g. they literally announced a Notion replacement (Space) alongside an integration that lets users spend their ChatGPT subscription tokens inside Notion. Notion has no leverage to push back. OpenAI will capture all the value in the long run. They're going to repeat this playbook over and over again. All pure SaaS companies now have the sword of Damocles hanging over them.

Another Trojan horse: they'll keep building specialized AI models and agents for each vertical and selling them directly to enterprises, all while making those same SaaS companies offers too good to refuse. Once the models are safe enough for the mass market, they'll replace the whole stack. Any $10B+ SaaS company that doesn't own its entire stack, models included, will be a dead man walking within 1–2 years.

With RSI we eventually will have new models every hour
you're not crazy between anthropic and openai, a new model used to come out every ~10 weeks now it's every ~11 days

Really love when people solve unglamorous real-world issues. Kate has a genuine, self-driven curiosity about this industry and, obviously, a great track record. So I have no doubt she'll be successful.
Introducing my building an AI-native funeral company in public series. Our generation does everything online and we care about experiences. But the one experience we’re all going to have? Still feels like a 100 years out of date. Cringe. The US has over 15,000 funeral homes. About 80% are family owned. Rising costs, staffing shortages, retiring owners. The people running these businesses are BURIED in admin while serving people in the toughest moments in our lives. So where the hell does AI come in? • Give owners one place to manage cases, staff, suppliers, and payments • Help small teams serve more families by automating routine work • Reach new customers through digital marketing and online booking • Let families customize, plan and pay for a funeral online • Expand the offering with pre-need plans, customized ceremonies and aftercare Big-company infrastructure for small funeral homes. Can we pull it off? The end goal: a personalized goodbye without the luxury price tag all over US. Let's see!

Either AGI or GPT-5
We've figured out how to *pretrain transformers* with zeroth-order optimization and no backprop. Many of the core assumptions in optimization research are completely wrong. (paper out soon)

The most ironic outcome is the most likely: first job that AI will replace end-to-end will be AI/ML researchers
Netflix replaced their 15 years old recommendation algorithm with an LLM. It’s called "GenRec" and it completely changes how recommendation algorithms are built. For over a decade, the Netflix recommendation engine was a masterclass in feature engineering. Data scientists built thousands of complex, handcrafted features to figure out what you wanted to watch next. It required bespoke architectures. Massive infrastructure. Constant manual tuning. Netflix threw all of it away. They built GenRec, an LLM-backed ranker. Instead of translating your behavior into complex math, they just turn your watch history and metadata into a natural language sentence. They feed that raw text into a foundation LLM. The AI simply reads your behavior like a story, understands your evolving tastes, and scores the entire catalog in a single forward pass. No manual feature engineering. No complex bespoke architectures. Here is the part that should terrify traditional data scientists. This text-based LLM didn't just match the highly tuned production system Netflix spent years perfecting. It beat it. And it achieved those statistically significant gains using roughly 40x fewer labeled training examples. We are watching a massive paradigm shift in real time. The most complex predictive algorithms in the world are being replaced by models that just know how to read. If Netflix can replace their core product engine with an LLM, what complex system in your business is about to become obsolete?

I have a theory that the more a founder resists the urge to let their ego grow with their success, the further the company goes
Adam Neumann on why top-down management fails with great talent: "Top to bottom means you think because someone reports in to you, they have to do what you say." "But it's not true. This is not a dictatorship. They have free will." "If you hired someone, they're really talented, they'll go work elsewhere. The more talented they are, the more the top to bottom does not work. They won't be willing to do it. They shouldn't." "Great talent is not willing to be managed like this." "If you're gonna manage these employees and you wanna attract the best talent in the world, remember that power comes from influence, not control." "If you think they need to do what you said because you're their boss, you've already lost, and it's a matter of time till it doesn't work out. If they're okay with it... they're not the right employee for you, and you're not the right boss for them. There's no chance you're getting the best out of them." @AdamNeumann w/ @StevenBartlett

It's a very big jump from one company and one product (Claude Design) to a general conclusion. 1. The current state of the models: superior at text reasoning but weak at visual tasks. The timing of the Claude Design launch wasn't perfect. 2. Anthropic as a company has a relatively weak product/design culture in general. That makes product shaping harder for them, especially for design products, and leads to mistrust from the design community. That doesn't apply to all sectors and personas though. The engineering community (and many others) obviously loves Claude Code. It's an amazing engineering product, and Claude models are often the strongest for engineering tasks. OpenAI doesn't have these disadvantages (compare Codex vs. Claude Code in design and product sense), so they can be more successful in building a design agent. 3. Both Anthropic and OpenAI can secure the the best specialists from any industry, and have stronger in-house models than anyone else on the market. That factor alone sets up their future vertical experiments to be more successful.
Any attempt by OpenAI to go vertical into law, finance, medicine, or any other specialized sector is dead on arrival. Anthropic tried the same with Claude Design. Nobody talks about it anymore. It's really hard to go up the stack. Way harder than people think. Every vertical has an incumbent that became the default. Once that happens, the switching cost is purely social, not price or features.

A bot with 2,000 voices that can’t issue a refund is still a phone menu. Making agents sound human is becoming the easy part. The hard part is giving them enough authority to solve your problem without giving them enough authority to create a bigger one.
Introducing Gemini 3.8 Flash and Flash-Lite TTS, our new SOTA text to speech model with: - a new voice design experience - 2,000+ production ready voices - voice replication - support for 100 languages - voice remixing (soon) - #1 spot on Hume AI's voice benchmarks and more!!

Meta wants to sell to you and shop for you. It sells businesses tools to influence your purchases. Now it wants you to trust its agent to choose what you buy. I don’t want my buyer’s agent answering to a company that also gets paid by sellers.
exciting news!! we’re partnering with @PayPal to enable customers to seamlessly shop and checkout online with @Muse across all PayPal merchants worldwide. we will not rest until your muse can ship till he drops!!!

This is how you kill a marketplace. Make it effortless for one buyer to lowball 500 sellers. Sellers stop taking offers seriously. Real buyers stop getting replies. Your AI assistant just made the platform not worse, but obsolete.
How important is AI to Meta? Here’s one easy tell: One of the launch features of the Muse app was auto-negotiating for stuff on Facebook Marketplace. The poor product manager who owns Marketplace knows that millions of bots lowballing sellers will eventually kill the product. But this was escalated to Zuck by the Muse team and he said: “OK, we’ll poison Marketplace…but just a little.”

I'm not as bullish on Jev as a lot of people on X. The number of use cases where it actually makes sense is small: - It seems almost useless for any agentic harness. What's the point of optimizing the cost of the tool-decision step when the biggest cost is the reasoning itself, which Jev doesn't do? - I'm not sure it's meaningfully cheaper than open-source models like Qwen3.7 Flash. - Latency is good, but a) it's hard to think of many use cases where you need AI routing without some form of AI-generated content (which requires another model anyway), and b) chat models will keep getting faster and cheaper. The idea is interesting for the LLM world (drop 95% of the functionality and optimize the remaining use cases for latency), but it's not novel in an engineering world. Gutting a Ferrari makes it faster too, but most people still need the seats, the AC, and the trunk.
