Announcing our $130M Series A to build the Open Superintelligence Stack Led by Radical Ventures, with NVIDIA, Intel Capital, Dell Capital, and existing investors Train, deploy, and continuously improve your own models using our stack. Own your intelligence.

Congrats! I’ve been really impressed by what the small team has built and shipped, including products, open source libraries, and research. Appreciate the push towards openness.

We're excited to be joined by angels who are building the frontier themselves, many of whom we work closely with: @johnschulman2 (Thinking Machines), @dwarkesh_sp, @AravSrinivas (Perplexity), @karimatiyeh (Ramp), @levie (Box), @_milankovac_ (Tesla), @winstonweinberg (Harvey), @amspector100 (Flapping Airplanes), @jeffwang (Cognition), @_arohan_ (Core Automation), @marksaroufim (Core Automation), @mikeknoop (Zapier, Ndea), @eastdakota (Cloudflare), @BrendanFoody (Mercor), @devanshpandey (Standard Intelligence), @hwchase17 (Langchain), @nicoup (Fleet) and many more

Pre-training concentrated the frontier of AI inside a handful of closed labs. RL breaks that open: teams can now own their model-optimization loop — train directly on their product, optimize for their workflows, and ship agents that continuously learn in production. Own that loop and you build a compounding moat in the agentic era. The only missing piece was the infrastructure.

So we built the Open Superintelligence Stack — training, inference, and compute: › Training — hosted training, prime-rl (large-scale agentic RL), environments, sandboxes, evals › Inference — dedicated, serverless serving and continual learning › Compute — frontier liquid clusters We train our own open frontier models on it, and ship the same stack to our customers

We are grateful to serve over 6k+ customers, including many leading AI startups, neolabs and enterprises already building on our stack, from RL to compute, sandboxes, inference, environments and evals. In under a year, demand has scaled to over $100M in annualized revenue, alongside a large open-source community of 500+ environment creators and 100k+ downloads.

Proof it works › Ramp trained a 35B model on Lab to beat Claude Opus at spreadsheet search, 27% faster and far cheaper › Arcee used our full-stack for pre- and post-training Trinity, a leading 400b model › Zapier Turned AutomationBench Into a Continuous Agent Improvement Loop and much more

Beyond scaling every layer, we’re pushing towards the next frontier with research on: › Long-horizon agents and Recursive Language Models (RLMs) › Automated AI research and science › Continual learning — training and inference merging into one loop with models that learn in production The next frontier lab won't be closed.

We're a small team building open superintelligence: › Reach out if you want to partner training, deploying and continuously improving your own frontier models for your use case › Join us to build open superintelligence — we're hiring across all roles including RL, inference, distributed systems, full stack engineering and compute.

Series A? Feels like you guys have been around much longer. Congrats!

they thought it was a drought

lfg 🦋 (i think we should have done an early access program for this video it's such a banger)

fun fact: if you feed this announcement into Fable, it switches to Opus.

congrats guys! 🎉

Incredible! Congrats on the raise team! 🔥

@ClementDelangue LFG. 🚀🚀

@vincentweisser Congrats @vincentweisser @willccbb @asharoraa and team!

congrats!

holy shit

Only got around to watching the video now, and damn, you guys really have someone with very good taste! Banger video.

crazy valuation for a merch company. congrats X

Congrats 🍾

@carnot_cyclist huge!! congrats to the team 🚀🚀🚀

transcending the game

Chills

Fuck yeah

Great video!! Congratulations team!

@beffjezos Wow ! Congrats

congrats!!

@kelxyz_ congratulations guys!

Well deserved and another impressive milestone! Kudos 🫡

this is my lane. owned intelligence is the shift. not just bigger models, but models that learn with you, remember with you, coordinate around you, and compound your edge over time. open superintelligence needs open coordination. also, respectfully, i could put a dangerous amount of that startup money to work. 🦾

@willccbb LET’S GO! 🫡

LFG 🚀

That's awesome, congrats guys! 👏

@scaling01 🐐

Submitting my application here, I can use claude code and codex

gratz!

congrats to the team!!!!

soon we'll see thread on how to get $10,000 from Prime Intellect Airdrop🪂

congrats 🫡🫡🫡

Congratulations @PrimeIntellect team!
