Today we're launching @CautionHosting, a hosting platform for software you can't afford to have hacked.
Deploy sensitive workloads to secure enclaves in minutes and give customers cryptographic proof that prod is running the exact release you approved, not an opaque binary you have to trust.
Caution is built for payment processors, healthcare platforms, AI agents and inference, crypto infrastructure, and other sensitive systems. It removes the blind trust software runs on today: trust in the cloud host, in production admins, in CI/CD, and in the assumption that the code you reviewed is the code actually running.
We spent years securing systems responsible for over $600B in assets and hit the same wall every time: teams couldn't prove what was running in production. Now that AI can find and exploit zero-days faster than anyone can patch, "trust us" isn't enough. Infrastructure has to stay secure even when it's compromised, and prove it.
Verifiable compute becomes the default, like HTTPS did.

Today we’ve raised $52M Seed and we are announcing the public launch of S2.1 Pro.
>It can clone a voice from 5 seconds of audio
>2x faster than Cartesia & 1/6th the cost of Eleven Labs
>most expressive model with word level control over emotion, intonation, pacing etc
We support frontier AI companies including HeyGen, LiveKit, Retell, Sanas, and OpenArt all run our model in production.
If you're a business and we can't cut your voice AI costs by 50%, we'll give you 1 year of Fish Audio for free.
Book a demo: s.fish.audio/tmapke
To celebrate our first birthday, we'll give you 1 month of S2.1 Pro for free. Like, retweet, and comment “Fish” to get it.

If Hantavirus mutated into a global threat, it would unleash AI + biotech unlike anything we've ever seen.
> genome sequenced and public in 4 hours
> AlphaFold maps every protein target
> AI screens 10,000 drugs in 24 hrs
> 50 vaccine candidates designed simultaneously
> AI designed antibodies in days
> risk of death computed instantly
> decentralized trials launch globally
> enroll from home
> 20 countries manufacturing at once
> first doses in three weeks
> real-time dose characterization
> your genome + biomarkers determine your protocol
> variant map updates every hour
No one would wait for governments.

Two weeks without mobile internet improved mental health more than antidepressants and reversed roughly 10 years of attentional decline.
Screen time dropped 49% (314 to 161 min/day).
Claude Code's source was exposed last night, and one of the coolest things we found there was a tamogochi-like pet system.
Tomorrow (April 1), a rainbow `/buddy` notification should start appearing in your Claude Code terminal.
Here's how it works:
They also built anti-cheat.
When you first hatch, the model generates a name and personality (the "soul"). This gets stored in your config.
But the physical traits (species, rarity, stats) are never saved — they're regenerated from your account hash every time.
From the source: "editing config.companion can't fake a rarity"
So to recap — Anthropic built:
- 18 species with ASCII animations
- A gacha rarity system
- Shiny variants (1%)
- RPG stats (SNARK, CHAOS, etc.)
- An AI that watches your code and reacts
- Petting with floating hearts
- Anti-cheat
- A virality-optimized rollout
And I feel it is one of the coolest parts in the entire source leak.
