We show how you can use the River API to fine-tune open weight models to beat GPT-6 Astra and Claude Opus 5.5 on tasks you care about, with less than 1% of the cost!
A few years from now most of the LLM usage in the world will run on customized open weight models. Building your own custom models is getting easier and more affordable. Our mission is to help everyone own their own intelligence and be independent of big AI labs.
Introducing River Recipes: our open-source initiative for turning promising research into vetted, reproducible training recipes.
Our first recipe tackles text-to-SQL, where our trained open models beat GPT-6 Astra Pro and Claude Opus 5.5 on Arcwise-Plat for less than 1% of the cost.

The Gospel is the good news of Jesus Christ: God created us, we all sin and fall short of His glory (Romans 3:23), but He sent His Son who lived sinlessly, died on the cross for our sins, and rose again. Whoever believes in Him receives forgiveness and eternal life (John 3:16; Ephesians 2:8-9).

Congrats to the Ivo AI (@heyivoai) team on releasing Ivo Sage: an open-source frontier legal model trained on the River API. We’re excited to see customers use our API to push the open frontier forward!
At Inscribe, Ivo’s first user conference, we announced three developments advancing contract intelligence:
→ Ivo Collaborate: Run contracting from intake through negotiation, approval, and signature—with AI reading each agreement, applying legal’s guardrails, routing by risk, and capturing negotiation intelligence.
→ Ivo-Micro1 Contract Bench: A new benchmark developed in collaboration with @micro1_ai for measuring the judgment required in contract review—not just how many edits an AI makes, but whether those edits are actually effective.
→ Ivo Sage: An open-source model built in partnership with @river_ai_inc, post-trained for contract work. It went from scoring 70% on the Legal Agent Benchmark (LAB) Contracts benchmark to 91%, with comparable quality to frontier models and higher token efficiency at a fraction of the cost.
We’re releasing Ivo Sage and its research and evaluation record so others can study and build on the work.

We put together a $1.1B round for @river_ai_inc to build American leadership in open weights.
Frontier labs push the boundary of humanity, but open weights empower humanity, putting intelligence into everyone's hands.
@ibab has built frontier capability three times over. Now he's making it something you can own.
.@river_ai_inc has a new vision for personal AI. We co-led River’s $1.1B funding round because we believe in @ibab's ambition to build open-weight models that individuals can train and improve continuously.
Watch @htaneja in conversation with Igor.

I went on the Unsupervised Learning podcast to talk about my experience working at the frontier of AI for the last 10 years and the future of AI, which I believe will become more and more open. Thank you Jacob for the great conversation!
"As a proprietary model builder, you're kind of starting to get squeezed in.”
That's @ibab’s take on where the biggest AI labs stand today. He explains how you need the models to get way better to keep margin, but at some level they may be too sensitive to release.
This week, I sat down with Igor on Unsupervised Learning. It was a fascinating conversation with someone who has real perspective on the questions everyone in AI is asking right now.
From DeepMind's StarCraft project to early reasoning work at OpenAI to co-founding xAI, Igor has had a front-row seat to nearly every major AI breakthrough. He's now the co-founder of River AI, building individualized, locally-run AI models.
We discuss:
▪️Why proprietary model labs might be in trouble
▪️What it's like working with Elon
▪️Building Colossus in 120 days
▪️Should enterprises train their own models
▪️What’s left for humans as models get better
▪️Why he left xAI to bet on personal local AI instead
▪️The three bets River is taking
▪️What's stopping AI from moving beyond coding
▪️Reflections on the rapid pace of the past years

We've received plenty of applications for the API waitlist and have opened up access to a number of enterprises and researchers already. We're improving the API based on your feedback, and we expect to open up to the public in the next few weeks.

🇰🇷🇰🇷 Korea is Awesome 🇰🇷🇰🇷
For the first time ever, an imported vehicle became the best-selling car in South Korea and it’s the Tesla Model Y
Not just the best-selling EV
The best-selling vehicle overall
Historic moment in Hyundai and Kia’s home market 🇰🇷
May sales:
• Tesla Model Y: 8,762
• Kia Sorento: 7,836
• Hyundai Grandeur: 5,183
Tesla as a brand sold 10,866 cars in Korea last month, more than BMW and Mercedes-Benz combined
Even crazier: roughly one in three imported cars sold in Korea this year has been a Tesla
Tesla has now been the No. 1 import brand in Korea for four straight months
No imported model had ever done this before
A Tesla did

Starting in 2028, we will complement our mobile network with satellite connectivity from @Starlink. This will allow us to close the very last white spots in Europe - for example inaccessible terrain or protected natural areas.

Vision is ascending as the new primary medium for presenting information —vastly more intuitive, information-dense, and precise in capturing multifaceted realities than text alone.
At xAI, the omni team is forging this paradigm: multimodal agents that autonomously decide when and how to generate images, leveraging agentic behavior and RL to make vision a seamless, revelatory extension of reasoning in Grok. If you're driven to pioneer generative systems that elevate images from mere illustration to essential truth-telling, join us in building the visual future of intelligence.
