This is a super exciting release - Claude Fable 5 is the same underlying model as Mythos but with added safeguards. The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time.
I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build!
AI has transformed how video is created. We think the next wave is about understanding it.
Over the past few years, we've seen remarkable advances in video generation, editing, avatars, and creative tooling. An increasingly important problem is teaching machines to search, analyze, reason over, and extract insight from video - across massive libraries and live streams alike.
We're calling this video intelligence, and we're actively looking to back founders building here. We're most excited about companies pushing on the core capabilities:
- Video-native models - multimodal embeddings, temporal reasoning, and retrieval built specifically for video rather than adapted from image or text
- Real-time and large-scale pipelines - infrastructure for processing, indexing, and querying video at the speed and scale enterprises actually need
- Agentic and reasoning layers - systems that don't just retrieve clips but answer questions, surface anomalies, and take action on what they see
The models and infrastructure to make this real are appearing to be crossing a capability threshold right now. Multimodal foundation models are maturing, storage costs have collapsed, and enterprises are sitting on years of unstructured video with no way to use it.
That infrastructure unlocks a wide range of applications including media and sports workflows, security and physical operations, enterprise knowledge management, advertising analytics, robotics, and consumer products, where video has historically been dark data.
If you're building in video intelligence at the model layer, the platform layer, or in a vertical application, we'd love to talk!
Announcing Cofounder 2: Run an entire company with agents.
It's the infrastructure for the one person billion dollar company - orchestrating agents across engineering, sales, marketing, ops, and design.
(and yes that's my real grandma in the video)
Some quick updates, now Solacy - my design intern works well from Slack and figma tagged comments.
Solacy has it's own identity and skillsets, and asks question and gets smarter over the time.
🚨 Do you understand what happened in the last 12 hours?
> A CEO of a $200 billion company said on camera that 35% of new grads won't find jobs. He didn't even flinch saying it.
> Meta made $165 billion last year and is still firing 15,000 people because apparently record profit isn't profitable enough.
> Some random guy in Florida sold his entire house in 5 days using ChatGPT. No real estate agent, no commission, no experience. Just vibes and a $20 subscription.
> A man in Australia cured his dying dog's cancer with AI after every single vet told him there was nothing left to do. Built a custom vaccine from his couch.
> The guy who created Uber and left 300,000 taxi drivers broke is back. Building robots now because apparently ruining one industry wasn't enough.
> Tinder wants access to your camera roll. Your drunk photos, your 3am notes app meltdowns, your deleted selfies. They're calling it a "vibe check."
> Naval, the man who made hundreds of millions investing in software, just said software is dead. Four words and the entire industry felt it.
> And Anthropic removed the limit on how long their AI can think and then doubled everyone's usage for free. Because when the product is addictive enough you give the first taste away.
All of that happened today. Not this week, not this quarter. Today. A random Saturday in March.
This is worse than you being on meth.
GUYSSSS!!!!
Never thought solving my mum's struggle with shooting and editing content would turn into the next thing I'm obsessed with building. And I definitely didn't expect so many of you to feel the same pain.
100+ waitlisted users in the first 24 hours.
That response has been Unreal.

P.s. Would be editing all my content with it from now on.
Coffee is pink!
That line has been showing up across Bangalore over the last few days.
On the walls of Indiranagar.
On coffee machines.
Even in cafés.
Today, here’s the first glimpse of what it’s about.
We’re calling it @getjustpour
And yes - pink is intentional.
Coffee, especially at home, has looked and felt the same for years.
Brown. Black. Serious. Complicated.
We think it doesn’t have to be. We’re here to make coffee simpler, more convenient, and a lot more fun - without losing what actually matters.
This is just the beginning.
If the colour made you pause, you’re going to enjoy what’s coming your way.
Waitlist is live now 📌
