The best tech on earth!!! And the company is really aiming to be an ally for creatives and artist… wow wow wow wow

We're building something ambitious at @_hex_tech, and I couldn't be prouder of our team as we work to improve and accelerate data work in the AI era And I'm excited to share we raised another $70m to keep investing and growing! Read more on our blog: hex.tech/blog/series-c/

I take enormous pleasure in this: "uv run" is 6 characters same as "python", so you can switch between them and there's no jump. One of uv's best features @charliermarsh. ai.pydantic.dev/examples/

How will AI impact the economy? Can we defend against misuse? What policies would mitigate the risks of AI? Thrilled to share that @random_walker and I are writing another book to tackle these questions! Today, we release a paper laying out our argument: AI as Normal Technology.

It has fundamentally changed how I write software and idk if I want to talk about how. I don’t see much benefit to sharing, and I see a lot of potential downsides of people being assholes about it

Today we’re announcing a set of updates, starting with a new experimental feature for paid subscribers, audio uploads. You can upload an audio clip of your choice, and extend this clip either forward or backward by 32 seconds using up to 2 minutes of context. Audio uploads greatly enrich your prompting vocabulary. You can use audio to set tempo and mood, and explore from there. Maybe you’ve got a great intro but don’t know where to go next, or a full mix that’s missing the perfect bridge–in both cases, Udio can provide inspiration. Check out the video below for some examples (we’ve had a lot of fun with this).

Inspired by the success of LLMs, today on the blog we discuss how neural activity in the human brain aligns linearly with the internal contextual embeddings of speech and language within LLMs as they process everyday conversations. Learn more →goo.gle/4iiUoNj

There’s been a lot of talk comparing Llama 2 and GPT-3.5. So, I made a site to let the models fight it out. Each round, pick the output you like better. Let’s get ready to rummmmbllllle llmboxing.com

We're thrilled that @BornsteinMatt and @zanelackey have led the seed round for @Resourcely, a secure, self-service cloud infrastructure from co-founders @travismcpeak and @0xshellrider. Read more on @TechCrunch techcrunch.com/2022/07/26/re…

I attended a vibe coding hackathon recently and used the chance to build a web app (with auth, payments, deploy, etc.). I tinker but I am not a web dev by background, so besides the app, I was very interested in what it's like to vibe code a full web app today. As such, I wrote none of the code directly (Cursor+Claude/o3 did) and I don't really know how the app works, in the conventional sense that I'm used to as an engineer. The app is called MenuGen, and it is live on menugen.app. Basically I'm often confused about what all the things on a restaurant menu are - e.g. Pâté, Tagine, Cavatappi or Sweetbread (hint it's... not sweet). Enter MenuGen: you take a picture of a menu and it generates images for all the menu items and presents them in a nice list. I find it super useful to get a quick visual sense of the menu. But the more interesting part for me I thought was the exploration of vibe coding around how easy/hard it is to build and deploy a full web app today if you are not a web developer. So I wrote up the full blog post on my experience here, including some takeaways: karpathy.bearblog.dev/vibe-c… Copy pasting just the TLDR: "Vibe coding menugen was exhilarating and fun escapade as a local demo, but a bit of a painful slog as a deployed, real app. Building a modern app is a bit like assembling IKEA future. There are all these services, docs, API keys, configurations, dev/prod deployments, team and security features, rate limits, pricing tiers... Meanwhile the LLMs have slightly outdated knowledge of everything, they make subtle but critical design mistakes when you watch them closely, and sometimes they hallucinate or gaslight you about solutions. But the most interesting part to me was that I didn't even spend all that much work in the code editor itself. I spent most of it in the browser, moving between tabs and settings and configuring and gluing a monster. All of this work and state is not even accessible or manipulatable by an LLM - how are we supposed to be automating society by 2027 like this?" See the post for full detail, and maybe give MenuGen a go the next time you're at a restaurant!

Today we're delighted to launch Audio Inpainting, an innovative feature that allows you to seamlessly edit and refine your audio tracks. With Audio Inpainting, you can select a portion of a track to re-generate based on the surrounding context. This makes it easy to edit single vocal lines, correct errors, or smooth over transitions, so you can create the perfect track. The interface is experimental, and will continue to be updated over the next few weeks. Inpainting is available for subscribers starting today (only on desktop). We're excited to see you make the best of it. 1/5

Open source models are at the bleeding edge of AI - but most consumers have no idea how to use them. Enter a wave of products that bring these models to the browser (or app!), with consumer-friendly UI/tooling. More from me + @omooretweets on startups building here 👇

Important to keep in mind that everyone in AI (including OAI) uses and benefits from open-source and wouldn’t be here without it. It’s the tide that lifts all boats!

I have written up some thoughts on AI doom and x-risk, with a focus on why I find a fast-takeoff scenario highly implausible, and why I think that any world model derived from written language is insufficient for advances in real-world technology: addxorrol.blogspot.com/2024/…

Presenting: The Bridge. An AI Short Film utilizing Veo-2. I’m really proud of this one, as my goal (as always) is to push storytelling, performance, and narrative in this emerging art form. Every shot here utilized Veo-2, although there were a few post-generation tricks here and there. Hedra was used for the lipsync. Writing, Sound, and Editing were done by me. Yeah, I’m pretty proud of this one. Per usual, I’ll have a full run through of the production on the channel in a few days!

Today, we're announcing Claude 3, our next generation of AI models. The three state-of-the-art models—Claude 3 Opus, Claude 3 Sonnet, and Claude 3 Haiku—set new industry benchmarks across reasoning, math, coding, multilingual understanding, and vision.

Announcing Stable Diffusion 3, our most capable text-to-image model, utilizing a diffusion transformer architecture for greatly improved performance in multi-subject prompts, image quality, and spelling abilities. Today, we are opening the waitlist for early preview. This phase is crucial for gathering insights to improve its performance and safety ahead of open release.
